【Abstract】 Objective To investigate the status of organochlorine pesticides contamination in foodstuffs and human breast fat tissues in Shanghai and Yixing city. Concentrations of some organochlorine pesticides and their metabolites were determined in a wide variety of foodstuffs and human breast fat tissues by the method of GC-ECD. DDT and its metabolites were predominant among organochlorines,and these residues were found in 85% of the foodstuffs analyzed. HCHs,HCB and CHLs were detected in 64%,59% and 53% of the samples,respectively. Concentrations of HCHs,HCB and CHLs in foodstuffs were generally low; in contrast,very high concentrations of DDTs and HCHs were detected in human breast fat tissues from Shanghai,with the maximum values as high as 19μg DDT/g lipid weight and 17μg HCH/g,respectively. [Conclusion] The residue of organochlorine pesticides such as DDTs,HCHs,HCB and CHLs could still be detected in foodstuffs and human breast fat tissues collected from Shanghai and Yixing city though the levels were much lower than before.更多还原
