摘要：

A qualitative and quantitative study was carried out on DDT residue and its metabolites in commercially produced sun dried fresh water fish species of Dhaka city markets. Soxhlet method for extraction, Forisil Column Chromatographic method for clean-up and Gas Chromatograph with Electron Captured Detector (GC-ECD) for analysis were used in the present study. The results are alarming indicating that all the samples tested were found to be contaminated with DDT (Dichloro Diphenyl Trichloroethane) residue and its metabolites DDE (Dichlorodiphenylethane) and DDD (DichloroDiphenyl Dichloroethance). The concentration of total DDT in these fish samples ranged from 93.84 to11880.5 mu g kg(-1). The concentration of total DDT in all the fish samples were within the permissible MRL level recommended by FAO/ IAEA/ WHO, except only one sample. As DDT is a long persistent and bioaccumulative substance in the environment, intake of significant amount of this slow poison with our diet is a matter of health concern.
