Environmental Fate Constants for Additional 27 Organic Chemicals underConsideration for EPA's Hazardous Waste Identification Projects

摘要

Under Section 301 of the Resource Conservation and Recovery Act (RCRA), U.S.Environmental Protection Agency (EPA) Office of Solid Waste is in the process of identifying chemicals to be considered in projects called the Hazardous Waste Identification Projects. A previous publication (3PA/600/R-93/132) addressed 189 organics in these projects. The environmental fate constants and chemical hydrolysis of an additional 27 organic chemicals are addressed in the report. Sorption coefficients are presented in terms of the octanol/water partition coefficient and the organic-carbon normalized sediment/water partition coefficient. The ionization constant is given when the process affects sorption in the environmental pH range. Additionally, values for aqueous solubility, Henry's law constant, vapor pressure, and diffusivity are reported.
