Abstract
Total human intake in various exposure situation derived from consumption of alternatives of chlordane is calculated by using of multi-media environmental fate model. The magnitudeof ingested chemicals is converted into risk considering the ADI value of chemicals concerned. Alternative chemicals are evaluated in terms of risk potential, cost of them, benefit of life time extension of the wooden house. Major results obtained are as follows:
(1) Any alternative chemicals have low risk compared to chlordane from exposure analysis in tesed real environment.
(2) Tetrachlorvinphos and tripropyl isocyanurate are superior to chlordane from the view point of risk exposed to residents and workers but others are not by virtue of indoor exposure analysis. Residents pay more to meet their need for anti-termite treatment. Workers and residents receive more health risk from phoxim pyridaphenthion compared to that from chlordane.
(3) Multi-criteria analysis shows that tripropyl isocyanurate, tetrachlorvinphos and phoximare superior to others in terms of human risk, cost and benefit. Some criteria which are includedin MPD (Minimum Premarketing set of Data) are found to be inclined torwards a risk-emphasized evaluation.
