There are over 200 industrial waste land treatment sites in the United States, and a larger number of land treatment sites for municipal wastewater and sludge (Loehr and Malina, 1986). Land disposal of wastes has increased during the past decade and is projected to continue to increase in the future (Loehr and Malina, 1986). The study of organic chemicals in the soil environment has been dominated by agricultural chemicals (e.g., insecticides, nematicides and herbicides) and specific compounds that persist in the soil (e.g., PCB's, PBB's etc.). Therefore the document discusses methodologies utilizing simple properties of chemicals--half-life (T(sub 1/2)), log octanolwater partition coefficient (log K(sub ow)) and Henry's Law constant (Hc)--are developed to screen organic chemicals for potential plant uptake.
