RESEARCH 811 Organohalide formation on chlorination of algal extracellular products. Jan K. Wachter and Julian B. An delman* Organohalide-forming potential of algal ECP, derived from a number of algal strains, is determined and com pared under varied environmental con ditions. 818 X-ray analysis of airborne particu lates collected by an Andersen sam pler. Compound and elemental distri butions vs. particle size of laboratory particulates. Masaaki Iwatsuki, Sujith Ε Tillekeratne, Tsugio Fukasawa, and Tsutomu Fukasawa* This method allows X-ray diffraction and fluorescence analyses of soluble and insoluble constituents in the partic ulates sampled. 823 Comparison of a chemiluminescent and a tunable diode laser absorption technique for the measurement of ni trogen oxide, nitrogen dioxide, and nitric acid. James G. Walega,* Donald H. Stedman, Richard E. Shetter, Gervase I. Mackay, Toshio Iguchi, and Harold I. Schiff Comparison of these analytical meth ods supports the widespread use of chemiluminescence for measuring NO in ambient air. 827 Fogwater collector design and char acterization. Daniel J. Jacob, RueenFang T. Wang, and Richard C. Flagan* The rotating arm collector preserves the physical and chemical integrity of the sample at all stages of collection. 834 Evaporation rate of spills of hydro carbons and petroleum mixtures. Warren Stiver and Donald Mackay* A method is developed that uses readily obtainable experimental data for calculating the rates at which oil spills evaporate.
840 Aspects of the polycyclic aromatic hydrocarbon geochemistry of recent sediments in the Georges Bank re gion. Paul D. Boehm* and John W. Farrington PAH concentrations are directly re lated to the total organic carbon (TOC) and the silt/clay content of the sedi ments.
873 Composition and origins of aerosol at a forested mountain in Soviet Georgia. Thomas G. Dzubay,* Robert K. Stevens, and Phillip L. Haagenson The major component of fine particles in the Caucasus is ammonium sulfate from distant sources, but manganese-rich spheres from a smelter also are present.
846 Hydrocarbon and azaarene markers of coal transport to aquatic sedi ments. Robert C. Barrick,* Edward T. Furlong, and Roy Carpenter Molecular markers are used to distin guish significant natural and anthropo genic coal input from other regional fossil sources, such as street runoff and fuel oils.
883 Role of the free metal ion species in soluble nickel removal by activated sludge. Jeppe S. Nielsen,* Steve E. Hrudey, and Frederick F. Cantwell Nickel uptake from typical municipal sewage is directly proportional to free Ni 2+ ion concentration, rather than to total soluble nickel concentration.
855 Rapid conversion of S0 2 (g) to sulfate in a fog bank. Delbert J. Eatough,* R i c h a r d J. A r t h u r , N o r m a n L. Eatough, Max W Hill, Nolan F. Mangelson, Bruce E. Richter, Lee D. Hansen, and John A. Cooper Daytime conversion in the plume of an oil-fired power plant averages 3% S0 2 (g)/h compared with 30% conver sion when the plume is in a fog bank.
NOTES
860 Photoreductive dissolution of colloi dal iron oxides in natural waters. Τ. David Waite* and François M. M. Morel The light-enhanced dissolution of colloid iron oxides under conditions typical of natural waters is investigated, and the major controlling factors are examined. 869 Hydrocarbons in waters adjacent to an oil exploratory site in the western North Atlantic Ocean. Gunter Gassmann and Roger Pocklington* High-resolution GC gives results different from the recommended fluorescence method when the anthropogenic signal is small relative to the natural background of hydrocarbons.
887 Trace element partitioning during the retorting of some Australian oil shales. Leslie S. Dale* and John J. Fardy Comparison of elemental mobilities demonstrates the variability in the degree of partitioning for each of the samples during retorting. 890 Reduction of low molecular weight halocarbons in the vapor phase above concentrated humic acid solutions. Jill Y. Callaway, Kasi V. Gabbita, and Vincent L. Vilker* Humic acid is found to decrease the air-water distribution coefficient of chloroform and trichloroethane. CORRESPONDENCE 894 Comment on "Mass transfer of volatile organic contaminants from aqueous solution to the atmosphere during surface aeration." Paul V. Roberts 894 Correction for "Field compatible calibration procedure for peroxyacetyl nitrate." Michael W. Holdren *To whom correspondence should be addressed. This issue contains no papers for which there is supplementary material in microform.
