提要：本文对上海地区使用的部分中药饮片(共41个品种,包括生品和炮制品计有288个样品)的有机氯农药(BHC,DDT)进行了残留分析,采用气相色谱法,ECD检测器测定,结果表明：所测样品的农药残留量均超过国家对粮食制订的限量标准(≤0.2g/g)。中药经炒和炒炭后,农残量有降低趋势,一些需添加敷料的蜜饯和酒炒炮制品,其农残量大于生品。 Abstract: This article analyzes residues of organochlorine pesticides (BHC, DDT) of some Chinese herbal medicines (a total of 41 varieties, including raw and processed products) used in Shanghai, using gas chromatography and ECD detection. The determination of the device showed that the pesticide residues in the measured samples exceeded the national standard for food production (≤ 0.2g/g). After fried and charcoal-fertilized by Chinese medicine, the amount of residual pesticides has a tendency to decrease. Some candied fruit and wine products that need to be added with dressings have more pesticide residues than raw ones.
