摘要

The magnitude and fate of some pesticide chemicals in Korean foods were studied with particular reference to oil-bearing crops and related products. Application of the chemicals was made under conditions of actual agricultural practice. Analytical methodologies included nuclear activation, gas chromatographic, spectrophotometric and radiotracer techniques. Residues of benzene hexachloride, heptachlor, heptachlor epoxide, aldrin, dieldrin, endrin and DDT found in refined vegetable oil samples were below or within the tolerance limits set by international organizations and as such, these are unlikely to present any toxicological hazard to the consumer. Also, residues of the herbicides nitrogen, alachlor and butachlor applied to oil-bearing crops were not detected in the seeds. Studies on exp 14 C-BHC residues in rice revealed that polishing and washing play an important role in removing a considerable portion of the residue. Data on the arsenic-containing neoasozine residues suggest that the products consumed by the human (grain and oil) contained residues below the tolerance limit and are unlikely to present any toxicological hazard to the consumer. On the other hand, relatively high arsenic concentrations (2.2 mg/kg) were found in the cake (serving as animal feed) and should be carefully evaluated in the light of toxicological data.
