| Research Abstract |
The total health risk evaluation framework was developed for the reference Japanese, due to the exposure to the environmental micro-pollutants, by integrating the dynamic performance/fate evaluation model, the external exposure evaluation model through dietary and respiratory pathways considering the food/feed import, and the health risk evaluation model. The framework was applied to the global scale radioactive fallouts, the lead and benzene in gasoline, the agrochemical DDT and other pollutants.
Dynamic performances of fallout radionuclides (Sr-90 and Cs-137) were evaluated for their cancer induction risks of the reference Japanese, to show quantitatively that the risk has been reduced since early 1970's, that the sr-90 related leukemia induction risk is larger than the Cs137 related risk, and that the risk is larger for the elder Japanese because of the lifetime accumulation of continuous exposure effect.
Lead and benzene once contained in gasoline, and widely used DDT were evaluated for their health risk to the Japanese. The health risk due to the exposure through respiratory and dietary pathways was evaluated and the effect of the risk reduction options was compared.
