Determination of the vapor pressure, aqueous solubility, and octanol/water partition coefficient of on a new importance during the past decade. These physical properties are being used by health and environmental scientists to study the fate and transport of potentially toxic materials in the environment and in biological organisms.

Volatilization of pesticides from water,edge of the potential for volatilization is useful both for estimating persistence at the target site and for assessing possible contamination of adjacent nontarget areas. In this work we address the volatilization rate of pesticides from water bodies.

Soil degradation studies,The April 22, 1981 draft of the Environmental Protection Agency Guidelines (U.S. Environmental Protection Agency 1981) emphasizes metabolism aspects of soil studies. The intent is to identify breakdown products that might accumulate in soil. A single soil is recommended; it must represent the soil at intended application sites.

Comparison of biodegradation rates in laboratory screening studies with rates in natural waters,do not accurately simulate natural aquatic environments, where chemical concentrations are low (. and a variety of nutrient conditions and microbial species exist. As a result, legitimate questions have been raised about the reliability of biodegradability screening tests, and the ability of such te
