The levels of HCH and DDT were determined in 355 samples of eight main varieties of food , taken from five provinces and cities. The results show that the positive rate of HCH is 69%, of which 99. 44 % is in accord with the National Standards of Food Hygiene of China. As to DDT, the two rates are 42 % and 100 % respectively. The daily intakes of HCH and DDT are 0. 22 mg/ kg.bw and 0. 54 mg/kg. bw respectively, which are far below their corresponding ADIs.Compared with those in 1970s, the OCS residues have decreased significantly. Therefore the monitored varieties of food are safe to people's health展开更多
