Prasad, S S

This study examines how pesticide characteristics such as water solubility, molecular weight, bioconcentration, volatility, and soil absorption affect soil-to-water mobility, water-to-air dissipation, and water-to-biota accumulation when present in the environmental medium of preferred residence. The study concludes that chemicals that have low water solubilities tend to adsorb to soil, those that have low vapor pressures tend to dissipate slowly from water, and those that have relatively high octanol-to-water partition coefficients or low water solubility have a high potential for bioconcentration. Based on these findings, researchers should be able to predict the mobility of pesticides belonging to a particular category or family of compounds with unknown physicochemical properties and recommend ways to restore the environment. 13 refs., 13 figs., 4 tabs.
