对1990-1994年波兰采集的59个土壤样品中DDTs、HCHs、CHLs、HCBz和多氯联苯(PCBs)等有机氯农药的浓度进行了测定，以了解这些化合物的污染规模、空间分布和来源。使用 HRGC-ECD (63Ni) 和 HRGC-LRMS 进行有机氯的鉴定和定量。所有土壤样品均受到 DDT、PCB 和 HCH 污染，而少数样品中不存在 HCBz 和 CHL。滴滴涕在波兰土壤中以有机氯残留为主，而其他杀虫剂的浓度则低两个数量级。 DDT 的百分比组成（约 60% 的 p,p'-DDT）表明 DDT 在波兰土壤中的代谢非常缓慢。波兰六氯环己烷的空间分布与滴滴涕的分布相似，而六氯苯和六氯苯的空间分布则相当均匀。前苏联陆军基地土壤中的多氯联苯浓度是城市土壤的10倍，是耕地和森林土壤的100倍。
The concentrations of organochlorine pesticides such as DDTs, HCHs, CHLs, HCBz and polychlorinated biphenyls (PCBs) were determined in 59 soil samples collected in Poland in 1990-1994 to understand the scale of contamination, spatial distribution and sources of these compounds. Identification and quantification of organochlorines were carried out using HRGC-ECD (63Ni) and HRGC-LRMS. All soil samples were contaminated by DDTs, PCBs and HCHs, while HCBz and CHLs were absent in a few samples. DDTs dominated as organochlorine residues in Polish soil and on the concentration of other insecticides was two orders of magnitude lower. Percentage composition of DDTs (about 60% of p,p'-DDT) indicates a very slow metabolism of DDT in Polish soils. Spatial distribution of HCHs in Poland is similar to distribution of DDTs, while HCBz and CHLs are rather evenly distributed. PCBs concentrations in soil of the Former Soviet Union Army Base are 10 times higher then in urban soils, and 100 times higher then in cultivated and forests soils.
