机体组织中有机氯农药的残留,是食物被污染的反映。Kraybill 认为由各种环境污染所引起体内的有机氯农药残留中,来自食物的约占85%,这与 Mrak 的实际观测(88.3%)近似,这一论点在食物污染较少的爱斯基摩人的体脂测定中,得到支持。有机氯的亲脂性使其进入机体后,均匀地分布于体脂,其浓度比肝脏可高达10倍,当 DDT 或六六六进入机体后,体脂中的含量可有数倍或数十倍的增加,但在体脂中农药残留大量增加时,并不易发现相应的临床症状,故体脂含量可看作食物污染的一个重要指标。
Organochlorine pesticide residues in tissues are a reflection of food contamination. Kraybill believes that about 85% of the organochlorine pesticide residues in the body caused by various environmental pollutants come from food, which is similar to the actual observation of Mrak (88.3%). This argument is valid in Eskimos bodies with less food contamination Lipid determination, get support. Organic lipophilic lipophilic into the body, evenly distributed in body fat, its concentration than the liver can be up to 10 times, when DDT or BHC into the body, the body fat content can be several times or several times However, when there is a large increase of pesticide residues in body fat, it is not easy to find the corresponding clinical symptoms. Therefore, the body fat content can be regarded as an important indicator of food contamination.
