Description:
A Soil-plant-water microcosm was used to develop a data base for pesticide transport and metabolism and to determine the effects of varying environmental conditions and/or components on chemical movement in a terrestrial ecosystem. The system was used in a comparative transport study with lindane, fonofos, parathion, phorate, DDT, and carbofuran. The results demonstrated the importance of chemical structure, water solubility, and soil type in predicting comparative chemical behavior. The system was also employed in studies of the effects of crop abundance on chemical movement and the interactions between agricultural chemicals that can affect chemical movement. Studies were also conducted on the effects of plant type, plant nutrition, soil microorganisms, chemical interactions on pesticide transport, and metabolism. These studies emphasize the importance of ecosystem interactions in determining chemical transport through ecosystems and into food chains.
