根据文献报道及收检样品检测结果,中药材农药污染有以下特点:1、农药残留具有普遍性;2、种植药材中农药残留量较高,野生药材中仅痕量检出;3、中成药中农药残留量一般较低;4、同一地区的同种药材、同一药材的不同部位农药残留量也有较大差异;5、不易发生急性中毒事件,但慢性积蓄不可忽视;6、有机磷和氨基甲酸酯类农药检出率较低,残留量也低;7、药材炮制前后农药残留量无显著差异。中药材农药残留研究主要有两个方面:农药残留量测定和低残留绿色中药材生产研究。
According to the reports in the literature and the samples collected, the pesticide contamination of Chinese herbal medicines has the following characteristics: 1. Residues of pesticides are universal; 2. Residues of pesticides in planted herbs are high; only traces are detected in wild herbs; 3. Chinese patent medicines The pesticide residues in pesticides are generally low; 4. The pesticide residues in different parts of the same herb and the same medicinal material in the same area also have great differences; 5. It is not prone to acute poisoning events, but chronic accumulation can not be ignored; 6. Organic phosphorus and amino The detection rate of formic acid pesticides was low, and the residual amount was also low; 7. There was no significant difference in the pesticide residue before and after processing. There are two main aspects of pesticide residues in Chinese herbal medicines: the determination of pesticide residues and the research on the production of low residual green Chinese herbs.
