波兰虽早已禁用有机氯类农药,但生药中仍有污染情况。1969年用气相层析分析测得薄荷叶中的DDT残留量为0.12～1.56ppm,12个样品,平均为0.68ppm;甘菊中DDT残留量为0.19～2.75 ppm,14个样品平均为0.59ppm;又从各地收集的19个缬草样品,没有1个不含DDT及其代谢产物,但其含量均未超过1ppm。生药中农残量污染程度因地区环境不同而有差别。实验证明,栽培生药的农残量较野生品为低。1971年甘菊头状花序中的农残量测定结果为:野生的20个甘菊样品中DDT残留量平均为0.27ppm,其中2个样品较高
Although Poland has banned organochlorine pesticides for a long time, there are still pollution in crude drugs. In 1969, the residues of DDT in peppermint leaf were 0.12-1.56ppm by GC analysis, the average was 0.68ppm in 12 samples. The DDT residues in chamomile were 0.19-2.75ppm, and the average of 14 samples was 0.59ppm. Nineteen valerian samples collected from different locations did not contain DDT and its metabolites, but none of them contained more than 1 ppm. Pesticide residual pesticide pollution levels vary by region and environment. Experiments show that pesticide cultivation of crude drugs than wild products is low. In 1971, the pesticide residues in chamomile flower heads were measured as follows: the average residues of DDT in the wild 20 chamomile samples were 0.27 ppm, of which 2 samples were higher
