Impact/Purpose:
Natural and xenobiotic organic chemicals present in soil, water, and the atmosphere may be taken up by plants. There are several incentives to develop models describing the rates of transport, transformation, and accumulation of chemicals in plants and thus concentrations in plant tissues. It is likely that vegetation plays a significant role in determining the environmental fate of chemicals.
Description:
Natural and xenobiotic organic chemicals present in soil, water, and the atmosphere may be taken up by plants. Three-compartment mass balance model of a plant is developed to quantify the uptake of organic chemicals from soil and the atmosphere. The compartments are as follows: root, stem, and foliage. The model is applied to the uptake of Bromacil by the soybean from hydroponic solution, yielding results which compare favorably with experimental data. The intent is to provide a method by which chemical concentrations in various plant tissues can be estimated from information on chemical properties, concentrations in soil and air, and plant physiology. pplications and data requirements for validation are discussed.
