ESTIMATION OF 1992-1993 DIETARY-INTAKE OF ORGANOCHLORINE AND ORGANOPHOSPHORUS PESTICIDES IN FUKUOKA, JAPAN

To estimate Japanese daily intakes of organochlorine pesticides such a s hexachlorocyclohexanes (HCHs), 1,1,1-trichloro-2,2-bis-(4-chlorophen yl)-ethane (DDTs), dieldrin (aldrin), heptachlor-epoxide (heptachlor), and hexachlorobenzenes (HCBs) from foods, fish, fish products, meat, eggs, milk, and milk products were analyzed as major sources of these pesticides in the diet, Estimated daily intakes (EDIs) per person were 0.56 mu g for total HCH, 0.20 mu g for gamma-HCH, 0.09 mu g for dield rin, 1.42 mu g for total DDT, and 0.15 mu g for HCB, Similarly, daily intakes of organophosphorus pesticides such as malathion and chlorpyri fos-methyl were estimated by analyzing wheat and wheat products as maj or contributing foods, EDIs of malathion and chlorpyrifos-methyl were 0.22 and 0.24 mu g, respectively, Daily intakes of total HCH, dieldrin , and total DDT in fiscal year 1992-1993 decreased 29, 44, and 40%, re spectively, but gamma-HCH intake increased 167%, in comparison with re sults of total diet studies for fiscal years 1980-1984. It was also sh own that increase in gamma-HCH intake was due to recent increase in co nsumption of imported meat and meat products. Malathion intake did not change significantly, This method, which estimates EDIs based on conc entrations of pollutants in main foods and statistical data of food co nsumption from the Japanese National Nutrition Survey, is considered t o be sufficiently accurate for use as a simplified total diet study.
