Pesticide detection. Field-portable kits are designed to use “new and advanced” technologies to detect pesticides and herbicides in water, soil, and food. Accurate readings can be given in 45 min, at about 10% of the cost of conventional systems. Ohmicron 107
measures compounds by highperformance liquid chromatography and generates electron ionization spectra for herbicides and pesticides. Finnigan MAT 116 Fast toxic gas assessment. SCENTOGUN uses a photoionization detector for instant assessment of toxic gases in air. Detection of 0.12000 ppm is possible. Response occurs in < 2 s. Data can be transferred to personal computers. Sentex Sensing Technology 121
TFID detectors. Thermioniclflame ionization detectors contain GCtype detectors for sampling gas streams that contain phosphorus, nitrogen, halogens, and oxygenates. Detector Engineering & Technology
SOFTWARE Environmental fate. Environmental Fate Database can be used on PCs or on VAX/VMS computers. It contains more than 200,000 records that cover 15,000 organic compounds, metals, and polymers that are subject to EPA regulation or are of industrial significance. Technical Database Services 136

Mercury in air. The 10.523 on-line/ off-line mercury analyzer measures mercury in air at ultratrace levels by collecting it on a gold amalgam and analyzing by atomic fluorescence. Questron 124
Remote air sampler. Summa passivated 6-L canister uses EPA methodology (TO-14) to sample air for volatile organic compounds. It is used at remote sites and needs no power or pump to sample at 2-500 cm3/min. Samples are kept stable for future GC-MS analysis. Andersen Instruments 110
Fugitive emissions monitoring. OVA 108 organic vapor analyzer is designed for fugitive emissions monitoring; it can read 1-10,Ooo ppm. It meets specifications of EPA Reference Method 21. Foxboro 126
VOC Sampling. Automatic VOC composite sampler is used for volatile organic compounds in liquids. It offers a choice of nine methods and can collect 100 mL of samples at 0.21 mL/sample. Associated Design and Manufacturing 113
Right-to-know. Free E S b T series on community right-to-know consists of three articles on pollution, air toxics, and communication with the public on risk. American Chemical Society 127
H,S alarm. MiniH,S 2000 alarm is used to detect toxic hydrogen sulfide in the workplace. It fits comfortably in one hand, in a pocket, or on a belt. It gives an alarm when H,S reaches a preset level and can measure on a 0-300-ppm scale. MSA 115
High-level nuclear waste. “Resource Kit” tells how copper containers would prevent high-level nuclear waste from leaking into groundwater for as long as 1 million years, and could be used at the proposed Yucca Mountain, NV, repository, Copper Development Association 130
STANDARDS Organic quality control. Certified reference materials are available for mixtures of haloethanes, volatile organic carbons, and other such compounds for use in analyzing groundwater, wastewater, and drinking water. Ultra Scientific 141
