This review on the analysis of pesticides covers the period of December 1981to December 1984. Again, we relied heavily on the excellent coverage in the two main abstracting journals, Chemical Abstracts and Analytical Abstracts. We also covered the main repository of information on pesticide analyses, Journal of the Official Association of Analytical Chemists (J.Assoc. Off. Anal. Chem.) and the Journal of Agricultural and Food Chemistry (J.Agric. Food Chem.). Although there seemed to be no dramatic breakthrough to report, the following analytical techniques appeared to have made significant advances in the analysis of pesticides: capillary gas chromatography (GC); GC coupled with mass spectrometry (MS) for the identification of pesticide residues, metabolites, and contaminants (e. dioxins); high-performance liquid chromatography (HPL& with reversed and other bonded phases and electrochemical detectors; high-performance thin-layer chromatography (HPTLC) and quantitation by automated densitometry. Although an occasional report on paper chromatography, usually from a developing nation, may be found in the international literature, TLC has mostly displaced the older technique, paper chromatography. A few reports on the use of immunoassay for pesticide analysis of specific compounds have appeared in the literature and are reported in this article. As we have observed in previous reviews, the sensitivity of most methods has not gone beyond the picogram level, although capillary GC-electron capture (EC) is capable of detecting femtogram quantities. We emphasize again, that many r e p o in ~ the literature devote much space to cleanup procedures and sample preparation. The rule seems to persist that a clean sample gives the best results! This review is devoted mostly to the analysis of pesticide residues and standards but not pesticide formulations. Compounds which in themselves cannot be classified as esticides, but nevertheless exhibit similar chromatographic l&ehavior,are covered in this chapter and include polychlorinated biphenyls (PCBs), phthalate esters, chlorinated dibenzodioxins, and furans. We found many reports on the analyses in a variety of matrices of organochlorine, organophosphorus, carbamate, and synthetic pyrethroid pesticides. As in previous years, the first part of the review deals with general topics of pesticide analysis, followed by the coverage of specific classes of pesticides. For the sake of clarity, we have broken down the references according to specific topics, while endeavoring to cite papers from readily available journals, or if important enough and reported in more obscure journals, we have also given the corresponding citation from the abstract journal. GENERAL Basic principles and practices for the analysis of pesticides (6A), as well as improved cost-effective approaches to residue analysis (I3A), have been discussed in two recent publications. Chromatographic techniques for the analysis of hazardous impurities in pesticides have been described (3A). Collaborative studies help to control the systematic error of analytical methods (IIA), like GC (8A). Simplified methods for the quantitative analysis of pesticide residues have been summarized (24A). The behavior of pesticides in the aquatic environment (23A) and the analysis of pesticide residues in an agricultural settin have been reviewed (I4A, 22A). The separation ancf purification of pesticide metabolites (17A) and their identification by soft ionization MS technique (IOA) have been the subject of two papers. The nature, identity, and properties of nonextractable soil and plant 0003-2700/85/0357-1R$06.50/0

pesticide residues have been discussed (12A), raising the important problem of their analyses and the challenge to the pesticide analytical chemist. Advances in pesticide residue analysis in food have been reviewed in two recent publications (20A, 25A). The application of MS in the regulatory analysis of pesticides and industrial chemicals in food and feed commodities has been reviewed (4A),and HPLC has been compared with GC in food analysis (21A). Residue methods for the analysis of contaminants, among them pesticides, in milk and milk products have been reviewed (2A). Rapid screening methods for pesticide residues and mycotoxins in food have been discussed in a recent paper (7A). A number of review papers have dealt with the analysis of aromatic amines (9A), organochlorine compounds (9A, 15A), polychlorinated dioxins and furans (18A), and carbamates (IA, 19A). An empirical pattern-recognition scheme has been proposed for the interpretation of chromatograms of complex mixtures, provided that the experimental results are highly reproducible (16A).

BOOKS AND REVIEWS A number of recent books or new editions of previously published books on the chemistry of pesticides have appeared during this period: the second edition of a book on organic plant protective agents and pesticides (1OB);the third edition of the International Pesticide Directory (12B); on the metabolism and mode of action of pesticides (8B);Vol. 2 of the Pesticide Analytical Manual by the Food and Drug Administration (7B) which continues to be an invaluable guide to the pesticide analyst; the 7th edition of Pharmacological and Chemical Synonyms (13B); Volume 3 of CIPAC methods for pesticide formulation analyses, containing the latest methods for pesticides distributed internationally (9B). A number of useful review articles covering the analytical methods and chemistry of pesticides are recommended reference material for the practicing pesticide chemist: chromatography of pesticides (6B);analytical methods for drugs, pesticides, and industrial chemicals (4B); bound pesticide residues in soil and plants (11B); pesticides in food (21B). Several books which have been published during this reporting period are on the topic of environmental chemistry, including pesticides (lB, 14B). A three-volume treatise on the analysis of pesticides in water, published recently, covers the literature through 1977 (3B). The 8th edition of Approved Methods by the American Association of Cereal Chemists might be useful for the chemist wishing to analyze fumigant residues in cereals (2B). Specific classes of pesticides have been covered in recent books and reviews: the metabolism and analysis of pyrethrins and pyrethroid insecticides ( 1 7B, 23B); the chemistry of orchlorinated dioxins (18B); ganophosphorus pesticides (5B); the metabolism of fungicides (19B); 5th edition of the useful Herbicide Handbook (20B); and a series of review articles on the triazine, substituted urea, and phenoxyalkyl acid herbicides (16B, I5B, 3B). SAMPLING AND CLEANUP General. Quality control by collaborative studies remains an important endeavor in order to establish the ultimate accuracy of samples for pesticide analyses performed in different laboratories (40C, 46C, 47C). An interlaboratory study has been performed to validate an official EPA method for base/neutral, acid, and pesticide priority pollutants (38C).

residue limits in crops (41C). General approaches for the identification of pesticide residues in foods of unknown origin were reviewed (37C). The stability of standard solutions of pesticides under different storage conditions was studied, and caution must be exercised in the case of several pesticides which degrade at ambient temperatures and are affected by light (15C). Analytical problems in the commercial development of plant protective agents (pesticides) have been reviewed (18C). Synthetic nitro musk fragrances have been shown to be potential contaminants using the recommended AOAC-multiresidue methods for cleanup and GC analysis ( 5 2 0 Research on automatic cleanup of samples prior to pesticide analysis continues and may eventually lead to commercial instrumentation (13C, 14C, 17C). Sample preparation for organic trace analysis, including that of pesticides, has been reviewed leading to recommendations for the practicing analyst ( 2 0 . The adsorptive properties of Tenax for the preconcentration of chlorinated pesticides from water and air has been investigated and found useful (IC). Gel permeation chromatography on Bio Beads SX-3 proved to be a universal cleanup method for many pesticides from fruits and vegetables (11C). Using macroporous organic sorbents (e.g., Separon SE) for the cleanup of phenoxy herbicides from water might result in high “blank” values in subsequent analyses due to trapping of analytes (36C). The chromatographic behavior of several classes of esticides (carbamates, phenylureas, etc.) has been studied gy HPLC with a silica gel column and a ternary mobile solvent system ( 3 5 0 Steam distillation for many pesticides, except toxaphene and methoxychlor, has resulted in better than 75% recovery from soil and plant tissues (32C). A patented micro cleanup and concentration apparatus consists of an LC column and filament concentrator (42C). A rapid procedure has been described for the extraction of pesticide residues from fabric

Cleanup of Environmental Samples. The US. Geological Survey has conducted a pilot study to investigate if ita water reference standard program for inorganic constituent can be expanded to include pesticides (1OC). The use of Amberlite XAD resins for aminocarb and metabolites from water, followed by GC, has been found to result in high extraction efficiency (23C). Preconcentration of organophos horus (19C) and chlorinated (4C) pesticides from water c o u d be achieved by the adsorption on graphitized carbon black. Pesticide Sam les from air have been concentrated on several resins: mberlite XAD for chlorinated, including fumigants (3C, 51 C); Tenax-GC for chlorinated (3C) and fenitrothion and aminocarb (21C); XE-340 for chlorinated ( 5 0 0 ; silanized silica gel for chlorinated ( 4 5 0 Phosphine methods have been evaluated with seven types of detector tubes (22C). Although methanol and acetone were found to be the most frequently used solvents for the extraction of pesticides from soil, a theoretical approach based on the known molecular properties of solvents and compounds should lead to a more efficient process (6C). Two methods for the isolation of “dislodgeable” foliar residues of sulprofos, permethrin, and methomyl were compared, and the method which does not use a surfactant is preferred as being the more rapid one (48C). Isolation from Fats and Oil. The analysis of PCB’s in industrial oils has been studied and recommended procedures were developed (43C). Sweep-codistillation cleanup procedures for organochlorine pesticide residues, PCB’s, and pentachlorophenol from animal fat have been described (26,33C). Less volatile pesticides (carbaryl, parathion, and aldrin) have been isolated from fat using a simultaneous steam distillation and extraction apparatus ( 9 0 Different methods for the isolation of pesticides from fat and lipids have been the subject of further refinement and innovation: PCB’s in fish (3OC);.lipophilicorganochlorine pesticides in fat (39C); gel permeatlon chromatography (29C); for milk and oil seeds (27C); the optimization of alumina adsorbent (12C). Nonfatty Products. The multiresidue method for pesticides in nonfatty foods has been further improved (28c). The multiresidue method has been successfullyapplied to the analysis of quinomethioate in apples and oranges (20C). The same method has been applied to the analysis of pesticide residues in kiwifruit, apples and berries. (160. The extraction

efficiency of various solvents for pesticide residues in plants demonstrated that methanol was generally the most effective solvent (49C). Method for the analysis of residues of organophosphorus compounds (OP compounds), ethylenebiddithiocarbamates) (EBDC), Fusarium toxins, and total Br in barley, malt, and hops have been developed (44C). Specific Compounds. Water samples containing chlorophenols (not pesticides in the strictest sense) have been enriched prior to GC/MS on Sep-PAK CISreversed-phase adsorbents (34C) and on XAD resin and activated carbon (5C). Steam distillation for the recovery of phenols from soil has been evaluated (31C). Two adsorbents, XAD-2 and Florisil, have been evaluated and found highly efficient for the sampling of 2,3,7,8-tetrachlorodibenzodioxin (TCDD) (7C). Abscisic acid and indolyl-3-acetic acid have been separated by a three-phase extraction and dialysis technique (25C); another purification method for abscisic acid involved an initial extraction with buffered (pH 8) methanol and then hexane, extraction into ether at pH 3, and final purification on Sep-PAK CIS(24C). GAS CHROMATOGRAPHY (GC) Capillary GC. The advanta es of capillary vs. packedcolumn gas chromatography is t[e increased resolution and shorter analysis time (500). Comparison of retention ratio data for pesticides separated on packed columns and capillary columns has been made (150). Relative retention times of 194 pesticides have been determined on a 15-m long capillary SE-30 column (350). Sample preparation of biological and environmental samples for capillary GC has been reviewed (330). Pesticide residues in foods which were difficult to analyze by packed-column GC were determined by capillary GC using a split/splitless inlet system and electron capture (EC) detector (120). Multidetection of pesticides analyzed by capillary GC was achieved by parallel N- and S-specific detectors (130). Using two capillary GC columns in parallel was found to be suitable for the analysis of PCB’s and chlorinated pesticides found in the same sample (380). Similarly, combining two capillary columns and connecting them to a selective flame photometric detector and EC detector, the authors screened over 100 halogenated and OP-pesticides (440). On-column injection of samples analyzed by capillary GC-, combined with MS gave higher sample transfer and greater sensitivity than the splitless injection system (470). Other applications and innovations involving capillary GC which have been used for pesticide analysis are as follows: capillary GC/MS computer identification of pesticide metabolites and confirmation of pesticide residues (180); fused silica on-column injection of chlorinated pesticides with an ultra-lowvolume rotary valve (190); automated pesticide residue analyses of food by fused-silica capillary column GC (160, 430); 50-hm (i-d.) capillary GC for fast GC of chlorinated pesticides detected by EC (390); the use of a polar glass capillary column using polyethylene glycol adipate as stationary phase for a large number of pesticides (340). Specific examples of the application of capillary GC which have been reported are as follows: toxaphene, identified by electron impact chemical ionization (C.I.) MS (370); ethylenethiourea and propylenethiourea in hops, beer, and grapes (320); separation of PCB’s and EPA’s non-priority pollutants on wall-coated fused-silica open tubular columns (290,200). Retention indexes for chlorinated benzenes and biphenyls have been determined for programmed temperature capillary column GC (310). A useful technique for the automated development of an optimum temperature program for capillary GC has been reported (420). Detectors for GC. Selective detection for haloforms and herbicides in water has been discussed, including EC, MS (sin le ion), and flame photometric detectors (60). Further mocfification of the Hall electrolytic conductivity detector (140) and an interlaboratory study of the Hall detector for halogen-containingcompounds (PCB and pesticides) has been completed (90). False positive halogen responses by the Hall detedor of eggplant extracts were found to be long-chain fatty acids (70). During the ast 2 years, several new GC detectors have been developed a n i evaluated: a high-temperature DC EC (400); a detector made of boron nitride which can be used alternatively in the photoionization and electron capture modes

A computer program in BASIC has been written to combine data from an EC and a flame photometric detector (410). GC/Mass Spectrometry. GC coupled to MS continues to he a favored techniaue for the absolute identification of pesticide residues and metabolites as attested by a number of recent publications: negative ion C. I. MS (450); the evaluation of an automatic method for the detection of chlorinated pesticides by a cornhination of GC/MS under the control of an DS55 data system (36D).Positive and negative ion data, simultaneously obtained under C. I. conditions, and coupled with a fused silica capillary GC-column, has been found useful in the identification of pesticides which are on the list of EPA priority pollutants (5D). The confidence limits for the detection of 2,3,7,8-TCDD by isotope dilution GC MS have been discussed in a recent review (28D). A new C/MS methodology has been found to he suitable for the analysis of insect pheromones (170).

HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC) Detectors and Columns. HPLC continues to find a useful place aa an analytid tool for the separation and determination of pesticide residues. One of the shortcomings of this technique has been the lack of specific detectors, so that the few reporb of new HPLC detectors applicable to pesticide analysis are doubly welcome. The commercially available photoconductivity detector has been evaluated for a number of pesticides below ppm (2IE)and has been applied to the analysis in fruits and vegetables of the fungicides captan, folpet, and captafol at the ppb level (22E).Thirty-five pesticides and metabolites have been successfullyanalyzed by HPLC using a fluorescence detector (13E). Quenched and sensitized phosphorescence of polychlorinated naphthalenes and biphenyls has been utilized for the detection of these com ounds separated hy liquid chromatography (IOE). RadiolaLled "C organochlorine pesticidea have been simultaneously detected after HPLC with a UV detector and a radioactivity flow detector (160. An impmved interface between a liquid chromatograph and an electron capture detector promises to offer specific detection capability for organochlorine compounds (6E). Organothiophosphate insecticides have been detected after HPLC hy on-line photo1 sis and electrochemical detection (SEI. Jignificant advances have been made on interfacing HPLC with MS and applying this technique to pesticide problem: a report on the modification of the Vespl desolvation chamber on a Finnigan 4500 MS (I9E); the design of a gas-nebulized direct liquid introduction interface (IO;a postcolumn buffer addition for the thermospray device suitable for HPLC and MS spectra of carbamate and urea herbicides W E ) ; the comhination micro-HPLC and MS for on-line analysis of phenylurea herbicides (24E). A special Pt-packed short precolumn connected to a Clereversed column was capable of separating aniline from phenylurea herbicides in water ( I I E ) . Phenols and substituted henols resent in water were fmt pasaed through cyclobexyl E ndeco ! ase column, eluted with methanol, and separated by HPLC on Sepralyte C8 (7E). Several reversed-phase columns have been evaluated for the analysis of plant hormones ( I S E ) . Parathion and metabolites in h l d serum have been directly analyzed by injecting serum samples on to a microcolumn, LiChrosorh RP-8 and using water or aqueous methanol as mobile phases (24E). Applications. HPLC haa found wide use for the solution of numerous pesticide analytical problem. HPLC of pesticide residues in environmental samples has been reviewed (4E). Retention data of 560 drugs and insecticides from reversedphase HPLC have been published (5E). Airborne pesticides, after concentration on Tenax and desorption, were analyzed by HPLC and detected by W or electrochemid detector (for phenols) @E). Oxamyl and ita oximino metabolite have been analyzed by HPLC on a Zorhax ODS column after cleanup through a Sep-PAK (17E).A simplified HPLC method for glyphosate in fruits and vegetables has been developed and is based on postcolumn fluorogenic labeling (15E). Dithiocarbamates have been analyzed by HPLC on two different types of bonded phases and by the interaction of tetraalkylammonium salts (IZE). The experimental insecticide, nifluridide, from water has been analyzed hy HPLC on a LiChrasorh RP-I8 reversed-phase column after concentration on a Sep-PAK CIScartridge (23E). EPAs priority pollutants have been analyzed by HPLC on ODs-bonded phases (SO. HPLC has been used to calculate quantitative structure-activity relationships for herbicides based on the hydrophobicity of these compounds (3E). ANALYTICAL CHEMISTRY. VOL. 57. NO. 5, APRIL 1985

THIN-LAYER CHROMATOGRAPHY (TLC) Although most advances in pesticide analysis have taken place during the past 2 to 4 years in the fields of GC and HPLC, thin-layer chromatography (TLC) has retained its status as a valid and simple method for qualitative and, in the view of some, even quantitative method of analysis for pesticide residues and metabolites. It appears that many papers on this subject originate from researchers in less developed countries, which is plausible due to the lack of sophisticated instrumentation and the shortage of repair facilities in these countries. A review paper on the application of two-dimensional TLC to the analysis of environmental pollutants, inorganics, and pesticides covers the literature through early 1982 ( 2 2 9 . A novel technique for the analysis of organophosphate (OP) insecticides and their metabolites combines TLC and MS without the elution of substances from polyamide-TL plate by the direct introduction of the separated substances into the ion source of the MS (2F). Several papers report on the TLC of acetylcholinesterase-inhibitinginsecticides, as follows: OP compounds are visualized on the plates with cholinesterbe reagent and a suitable substrate, e.g., indoxyl acetate or acetylthiocholine (13F), and quantified by reflectance scanning; screening for OP and organochlorine compounds in animal tissues (1OF); OP compounds in vegetables (11F);OP and carbamates in fruit and vegetables (21F);and OP residues in toxicological investigations (20F). Several carbamates have been separated on thin layers of silica gel coated with 1% zinc acetate (16F). A newly developed spray reagent for organochlorine compounds on TL is 3,3’,5,5’-tetramethylbenzidineat a detection limit of 0.2 pg (SF). Thionophosphoric esters and decomposition products can be visualized and semiquantified with the 12-azidereagent (IF). Herbicides which inhibit the Hill reaction (photosynthesis) can be visualized on TLC plates by a spray of chloro last homogenate and 2,6-dichloroindophenol and exposure o?the plates to white light (7F). The resolving power of solvents for TLC of triazines was found to be related to the lipophilicity of the solvent (6F).A structure and TLC mobility relationship for tebuthiuron and related compounds has been established (15F). Indole-3-aceticacid decomposes rapidly on silica gel plates, and caution must be exercised when using this chromatographic technique for IAA (SF). Direct reflectance densitometry and decrease in fluorescence were used for TLC of herbicides on silica-gel layers precoated with a fluorescence indicator (4F). Organic acids have been separated on TLC using CaSO, plates; this technique may be suitable for acid pesticides (3F). High-performance TLC (HPTLC) has been used for the analysis of organotin compounds (SF). According to the authors (18F),they have been able to analyze toxaphene uantitatively by using a commercial extinction registering levice with integrator. Paraquat in toxicological investigations has been determined by TLC on silica-gel lates and visualized with Dragendorffs reagent (19F). A fielftest has been developed for the analysis of PCB’s by TLC and a quantitative evaluation by densitometry later in the laboratory (17F). Biphenyl residues in citrus and urea, carbamate, and anilide herbicides have been analyzed quantitatively by TLC and densitometry (14F,12F). MISCELLANEOUS TECHNIQUES Analytical techniques for pesticides are not exclusively based on chromatographic methods. This section is a review of other significant methods which have been described in the literature during this reporting period. A commercial automatic analyzer, Automatic Modules for Industrial Control Analysis (AMICA), produced in Switzerland, has been tested for the analysis of herbicides (1G);the unit consists of a liquid processor, a spectrophotometer, and an autosampler. A method is described for the calculation of pesticide partition between sediment and water at levels below the sensitivity of most methods (8G). Fluorine-containing pesticides have been analyzed by fluorine-19 Fourier transform NMR (17G). Toxic contaminants of technical-grade organo hosphorus insecticides have NMR 79G). Triple auadruDole mass been determined with 31P spectrometry has been applied to the andysk at f6mtogram levels of TCDD (20G). 4R

A number of pesticides have been examined on paper support surfaces for room temperature phosphorescence, which, it is claimed, mi ht be a suitable method for quantitative analysis (22G). Jimilar results were observed by the enhancement of luminescence of certain pesticides by the utilization of heavy atoms (13G). A bioluminescence assay for some aldeh de-containing insect pheromones utilizes the luciferase-catd zed oxidation of long-chain aldehydes in the presence of reiuced FMN (18G). The sulfur-containing insecticides methomyl and aldicarb and others containing nitro groups have been analyzed by differential pulsed voltammetry (polarography) (21G, 2G). Trichlorobiphenyl has been analyzed by adsorptive stripping voltammetry (15G). Capillary isotachophoresis has been utilized to quantify the level of asulam in soil (IIG). For the analysis of PCBs in the field, portable monitors have been developed, based on the principles of photoionization and IR spectroscopy (4G). Several analytical techniques recently reported are based on biological principles and reactions. For example, OP compounds in an aquatic environment were analyzed by an acetylcholinesterase assay using tritiated acetylcholine and extracting the released [SH]aceticacid with an organic solvent (IOG). Immunoassay continues to interest a number of investigators as to its applicability to pesticide analysis: 2,4-D by radioimmunoassay (14G);diclofop-methylby enzyme- and fluoroimmunoassay (19G);abscisic acid by a combination HPLC and radioimmunoassay (12G). Two reports on the use of immobilized cholinesterase electrodes demonstrate the feasibility of this technique in the analysis of OP and carbamate insecticides in the aquatic environment (7G, 16G). By use of an enzyme preparation of aryl hydrocarbon hydroxylase, it was possible to screen for compounds like dioxins, dibenzofurans, and PCB’s, which are known enzyme inducers (6G). By use of the organism Chlorella sorokiniana, a bioassay for atragine residues in soil was developed (5G). Most pesticide analysts are reluctant to reuse spent solvents in the extraction of pesticide residues from crops and other matrice$. A modified condenser has now been developed with which it was possible to reconstitute solvents, which when reused, showed no appreciable differences in results compared with those from fresh solvents (3G). CHLORINATED PESTICIDES General. The separation of chlorinated pesticides on columns of silica gel of varying degrees of porosity has been investigated (12H). Studies have shown that freezing of plant samples from the time of collection until final analysis assures optimum recovery (14H). In order to account for the interference of PCBs in the GC of DDT and related compounds in marine samples, chromatograms from an in-line KOH microreactor and a regular GC column are compared by means of a microprocessor (6H).Chlorinated pesticides have been determined in urine by neutron activation analysis (33H). Analysis of Human and Anihal Tissues and Fluids. Analytical methods and results for chlorinated pesticides in human milk continue to be reported (SH,32H, 41H). Modified cleanup methods for the GC of chlorinated pesticides in bovine milk have been developed (IH, 39H, 43H). Chlorinated compounds and phenols in tissues and body fluids of the rat have been analyzed by capillary GC (38H). GC methods have been used to determine organochlorine compounds in human liver samples (24H) and semen (40H, 44H). Twenty-one oranic industrial chemicals and pesticides were added to human %lood and extracts analyzed by GC; recoveries for hexachlorocyclopentadiene, mirex, and trans-nonachlor were unsatisfactory (4H). A collaborative study has been completed on a rapid GC-screening procedure for pesticides and PCB’s in fish (15H). Organochlorine pesticides, PCBs, and volatile halogenated hydrocarbons in fish from the upper Rhine and Lake Constance were analyzed by GC (2H). Environmental Samples. Organochlorine compodnds in wastewater were analyzed by capillary GC/MS (18H). Organochlorine compounds in river sediment were determined by capillary GC (45H). Chlorophenols in aqueous model solutions have been separated on TLC (42H). Analysis of Foods and Feeds. A simple fingerprinting technique for screening organochlorine residues in foods consists of pressing cut vegetables against o-tolidine-im-

Multiresidue analysis of organochlorine, organophosphorus, and synthetic pyrethroid pesticides in grain has been performed by GC and HPLC (323. Sample preparation of oil seeds and ve etable oil refinery byproducts, prior to pesticide analysis, has%een reported (37H, 47H). Pentachlorophenol. The widespread use of pentachlorophenol as a wood preservative and the possible health concern due to possible exposure have led to the development of a number of analytical methods and studies: the analysis of PCP in hardwood chips as the acetate by GC (17H);GC of the meth 1ester of the formulation and extract from treated ; of the methyl ester on QF-1 stationary timber (5danalysis phase or neopentyl glycol succinate (plus H3P04)for direct determination (28H); a simple spectrophotometric determination for water samples (1IH);the determination of pentachlorophenol in workers’ urine by HPLC after hydrolysis (13H) and in drinking water and urine by HPLC and electrochemical detection ( 3 0 ; and finally, the detection and determination in cultivated mushrooms as the methyl ester by GC (31H). Speoific Pesticides. The effect of water concentration in various organic solvents on the extractibility of dieldrin and methomyl residues has been investi ated (46H). ChIordane components in fish have been idended by capillary GC/MS (36H). Aldrin and dieldrin in soil were determined by mass fragmentography using heptachlor epoxide as internal standard (25H). Aldrin and endrin have been analyzed in sewage sludge by gas-liquid chromatography (GLC) (19H). The environmentalanalysis of toxaphene has been reviewed, and it was concluded that capillary GC with e3Ni electron capture detection in conjunction with MS is a suitabIe method (3423.Another approach to the analysis of toxaphene in water was taken by selecting and measuring representative peaks from a GC chromatogram and preparing individual calibration curves against “concentration of toxaphene” (26H). Toxaphene and chlordane in fish samples were determined by capillary GC coupled to negative chemical ionization (CI) MS (2.w.

ORGANOPHOSPHORUS PESTICIDES General. Two methods have been compared for the analysis of azinphos-methyl, anticholinesterase (in vitro) and HPLC; it was found that the enzymic method was faster but that several metabolites could be assayed by HPLC simultaneously (221). Another comparison was effected between GC/MS and HPLC/MS for the analysis of another OP comanalogue; the conclusion was pound, coumaphos and its (0) that LC MS interface is more efficient (361). A study was reporte on the use of HPLC for the analysis of parathion, chlorpyrifos, and chlorpyrifos-methyl from rat tissues (331). A field method has been developed which will indicate above-tolerance residues of parathion on citrus fruit (281). Urinary metabolites of OP insecticide, dialkyl phosphorodithioates, can be extracted with great efficiency from aqueous medium by the equimolar addition of tetraphenylarsonium cation (101). Several studies have been reported on optimum conditions for the analysis of OP compounds by GC: the effect of column temperature (131); the effect of sample concentration and

Another GC method for ethylene dibromide in citrus fruits (5 ppb) involved steam distillation from benzene-water (15) and cleanup of the dried benzene distillate by addition of silica gel impregnated with fuming H2S04( 5 N . A portable gas chromatograph operated a t ambient temperature and fitted with a photoionization detector was used to determine amounts of ethylenee dibromide above 19 ppb in air (4N). A method was developed for determination of phosphine residues in wheat based on reaction of PH3 with AgNO, in aqueous solution to form a yellow chromophore that was measured by spectrometry at 400 nm ( I O N ) . Blood and tissues from a person who had ingested aluminum phosphide was analyzed for phosphine by headspace GC on a column of Porapak Q with N-P detection (2N).

INDUSTRIAL CHEMICALS RELATED TO PESTICIDES A large number of papers were published on the analysis of various samples for polychlorinated biphenyls (PCBs), usually in the presence of organochlorine (OC) pesticides. Recent advances in analyses of PCBs in environmental and biological media (31Q) and PCB structure-activity relationships (37Q) were reviewed. All 209 mono-, di-, tri-, tetra-, penta-, hexa-, and heptachlorobiphenylswere synthesized and their spectrometric and chromatographic properties reported (23Q). A BASIC computer routine was presented for calculation of PCB concentrations using the individual peak-weight percent method and GC on a 5% OV-101 column (246). A laboratory data base for computer-assisted isomer-specific determinations of PCBs used a retention index system with n-alkyl trichloroacetates as marker compounds (39Q). Six technical Aroclors were separated into individual chlorobiphenyls that were identified by fused silica gel capillary column GC/MS (47Q). GC/high-resolution MS and MS/MS were compared for detection of PCBs and tetrachlorodibenzofuran (48Q). Time-pro rammed limited mass scan GC/MS for PCB analysis invofved selection of discrete portions of the mass range, adjusted automatically during chromatography to match elution times, to monitor the presence of characteristic groups of ions (509). Cyclodiene insecticides were determined in the presence of PCBs by photoisomerization reactions (28Q). Perchlorination to decachlorobiphenylwith SOzCl in the presence of AlCl allowed rapid determination of PeBs by EC-GC (46Q). bC pesticides and PCBs were cleaned up prior to GC analysis by gel permeation chromatography with the mobile phase methylene chloride-cyclohexane (43Q), by chromatography of fat samples on columns of silica gel (45Q),and on columns of silica gel containing 10% water (on-line method for extraction and isolation from meat and fish) (44Q). An analytical method for the determination of PCBs in motor and transformer oils, developed by the NBS in the certification of a standard reference material, involved preparative scale HPLC to remove interferences and high-resolution capillary GC on a nonpolar wall coated open tube with EC or Hall electrolytic conductivity detectors (29Q). The analysis of PCBs in oil was evaluated by an NBSIASTM round robin study involving 11oils and 19 laboratorles (3Q). Several GC methods for PCBs in oil were compared (14Q). Transformer oils were screened for PCBs by nondisperse

X-ray fluorescence spectrometric analysis of chlorine (17Q). Capillary EC-GC determined PCBs in electrical insulating liquids after dilution and Florisil column cleanup (40Q). The following additional determinations of PCBs, most by EC-GC after extraction and adsorption column cleanup, were described PCBs and DDE in human body fluids and infant formula (196);PCBs and OC pesticides in bovine serum (4Q) with an interlaboratory study (5Q);in sediment by pyrolysis GC(MS (20Q) and capillary column GC (276); in marine sediment by GC/negative CI-MS (15Q);field measurement of PCBs in soil and sediment using a portable gas chromatograph (42Q);isolation by steam distillation from fatty foods also containing OC pesticides (18Q);in herring meat and liver (1Q);in human milk and butter by capillary GC (38Q);in monkey milk and tissues (21Q);in industrial and municipal wastewaters also containing OC pesticides (22Q);in air samples with collection on polyurethane foam (25Q);in pigments (2Q); in biotic and abiotic marine compartments (9Q);in sewage sludges using packed and capillary column GC and MS (11Q); and in peregrine falcon eggs (30Q). Several agricultural chemicals were examined for contamination by polychlorinated dibenzo-p-dioxins (PCDDs) and related compounds by GC/MS (7Q). All possible PCDD isomers containing four or more C1 substituents were prepared by micropyrolysis of chlorophenates and their capillary GC/MS properties were studied (6Q). Concentration of solutions of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) by combined refluxing + nitrogen evaporation, vacuum evaporation, and nitrogen evaporation were compared; substantial losses were obtained only by evaporation to dryness under nitrogen (26Q). PCDD residues were determined in biological samples by C18-HPLC-UV(235 nm) using polycyclic aromatic hydrocarbons as calibration standards (36Q). Fish and deer samples were analyzed for TCDD by GC at low ppt levels (12Q). Soil and vapor samples were analyzed for TCDD by GC/MS (16Q). PCDDs and dibenzofurans were identified in human samples by capillary GC/MS (34Q). TCDD was determined at ppt levels in wastewater by extraction, cleanup on silica and alumina columns, and GC/MS (32Q, 51Q). 2,3,7,8-Tetrachlorodibenzo-p-dioxin and -tetrachlorodibenzofuran were determined in a soot sample from a transformer explosion by GC/MS after extraction and cleanup by carbon-celite, silica gel, and Zorbax ODS and SIL HPLC columns (41Q). TCDD in sugar (1ppt) was determined by GC high-resolution MS (49Q). dhthalate esters were separated from PCBs and OC pesticides on dual alumina and silica gel columns as part of an EC-GC analysis of environmental samples (35Q). Phthalate esters were determined in sediment at 1-5 ppb by GC/SIMMS (33Q). Polychlorinated naphthalenes (PCNs) in the presence of PCBs were determined in sediment by steam extraction to separate OC compounds from the matrix, hydrodechlorination of PCNs (but not PCBs) by in situ generation of “nickel boride” by treatment of NiCl, with NaBH4 in 2-propanol, and measurement of naphthalene content of the mixture on a capillary GC column (13Q). Polychlorinated terphenyls were analyzed in environmental samples by capillary GC/MS, silica gel HPLC-UV (207 nm), silica gel TLC, and perchlorination/GC (8Q). Polybrominated biphenyl residues were determined in animal tissue by GC after extraction with CHCl3-methanol(2:1) for liver and CH2C1, for adipose tissue (log). LITERATURE CITED 0ENERAL

INTRODUCTION This review covers analytical techniques applicable to the examination of coatings and coatings raw materials, substrates upon which coatings are placed, etc., since the last review in 1983 (14). The compiled references were extracted after searching Chemical Abstracts, Analytical Abstracts, World Surface Coatings Abstracts, and the Journal of Coatings Technology. The contents are divided into 18 categories for ready access to the reader. Readers are advised to survey the entire review for the analysis of specific paints, coatings, or related materials may be found in each section. The five most highly referenced categories are Chemical and Electrochemical, Gas Chromatography, Nuclear Magnetic Resonance Spectroscopy, Surface, and Thermal Analysis. New or unique applications to estab!ished analytical techniques also appear throughout this remew. Several general review articles have appeared dealing with the use of analytical techniques for the examination of coatings (1,21,22,23).General analytical papers were also published on more narrow aspects of coatings technology, including emulsion paints (28,311, realistic paint testing (23),and fire retardant coatings (17). The role of ASTM in coatings research and development was the subject of a recent publication (36). Analysis of inks also received special attention (29) as 0003-2700/ 85/0357-15R$06.50/0

did general polymer analysis as detailed in a comprehensive book on this subject (16). The increasing role of the coatings analyst in dealing with customer complaints was the subject of a presentation (15)which cited four examples of how unique analytical approaches are frequently required to reach a resolution to a problem. The examination of coatings for forensic applications has found continued interest during this period (24,30,32)as has the analysis of fine art for conservation purposes (35). Special studies also appeared, including methods of latex cleaning prior to analysis (241, paint solubility testing (36), and a mathematical treatment of methods for calculating the flash point of liquids (34). The American Society for Testing and Materials (ASTM) has continued to provide methods for the examination of coatings. Methods relative to the determination of flash point received special attention, including the use of the Setaflash Tester (9,131, the use of a flash-no flash equilibrium method (ll),and the more traditional Tag cup apparatus (3, 7). ASTM procedures have also dealt with the examination of diatomaceous silica (6) and liquid paint driers (5). Standard practices have also appeared for the testing of specific coatings types, for example, wood furniture lacquers (81, lac resins (2), and clear and pigmented lacquers ( 4 ) were completed during this period. Ultraviolet cured coatings are a new area of @ 1985 American Chemical Society
