The targets of this international cooperative study is to make clear the characteristics of the health risk situations in Japan, India and Malaysia due to the environmental deterioration, the environmental monitoring practice and the health risk evaluation studies.In the last year of the three-years project, foreign cooperative investigators, Prof. Sharma and Prof. Aziz visited Japan at the same period from India and Malaysia respectively, to discuss on the application of the Fugasity model for the environmental fate analysis of DOT under the common and country specific situations. The Physiologically-based pharmacokinetic model was also discussed on Pb and DDT to relatethe dietary exposure of these pollutants with their accumulation on the human organ and tissues. In Japan, Lead in gasoline and agrochemical DDT were banned already in early 1970's. However the leaded gasoline has just regulated in India and Malaysia, and DDT is still used in India. The cooperative risk study will contribute very much for quantitative examination of the environmental risk management policies and their effectiveness.
