Abstract
In Japan the insecticide DDT had been used since 1946. In 1971, its use for agriculture and household pest control was banned because of the increased health effect and environmental contamination, and was fully banned in 1981 in production, sales and usage for every purpose. The actual use was stopped substantially in early 70's, however DDT and its metabolite DDE have been detected in environmental media, foods and human tissues and organs as well through the environmental monitoring and epidemiological survey. In this study, the Fugacity model is developed to evaluate the dynamic performances of DDT and DDE in both Japanese and Indian environment, where the agricultural use was banned in 1994, and the dietary exposure to DDT is evaluated for the reference Japanese and Indians for the past half century to compare the dynamic characteristics in the environment and dietary exposures.
