项目摘要

Chemical contamination caused by man-made organochlorine compounds such as PCBs, DDTs, HCHs, CHLs, and HCB were investigated in environmental samples collected in Poland. The resuls showed that relatively high concentrations of PCBs were present in soils from industrialized areas such as coal mining and chemical factories located in southern Poland, and coastal sediments collected at near shipyards in northern Poland. It is estimated that PCBs were used as chemical agents for machinery of coal mincs and an ingredient for paint for ships. Additionally, relativery high concentrations of PCBs and DDTs were found in soils from a former Soviet army base located in northwest Poland. These compouns were also present in sediment samples from lakes and ponds located in north, northwest and south Poland. The results showed that man-made organochlorines are ubiquitous environmental pollutants in the Polish environment.In order to make clear the presence of unidentified organohalogen compouns, contribution percentage of indentified (known) organohalogen compounds in extractable organic halogen (EOX) were determined in the Polish environmental samples. The order of concentrations of EOX was EOCI>EOB_1>EOI.The concentrations of EOX in harbor porpoise (Phocoena phocoena) were higher than those in the fish they eat. It is suggested that the EOX present in marine mammals is accumulated through the marine food chain of the Baltic Sea. The greater part of EOCI detected in sediment and biological samples was occupied by unidentified compouns. It is necessary to analyze individual compounds in EOX residue in Polish environment in order to investigate their sources and to evaluate the effects to wildlife and the people living in Poland.It is concluded that many halogenated compouns are spread over the Polish environment and that chemical pollution is occurring on the coastal areas of the Bay of Gdansk and the Baltic Sea.

由PCB，DDTS，HCHS，CHLS和HCB等人造有机氯化合物引起的化学污染，在波兰收集的环境样品中进行了研究。重新升压显示，来自工业化地区的土壤中存在相对较高的PCB，例如位于波兰南部的煤矿开采和化学工厂，以及在波兰北部造船厂附近收集的沿海沉积物。据估计，PCB被用作煤炭煤炭机械的化学剂，也是用于船舶油漆的成分。此外，在位于波兰西北部的前苏联陆军基地的土壤中发现了相对的高浓度PCB和DDT。这些组合也存在于来自北部，西北和南波兰的湖泊和池塘的沉积物样品中。结果表明，人造的有机氯是波兰环境中普遍存在的环境污染物。为了清楚地表明存在未识别的有机脂蛋白组合，在波兰中确定了可提取的有机卤素（EOX）中含水（已知的）有机体化合物的贡献百分比。环境样品。 EOX的浓度顺序为EOCI> eob_1> eoi。港口海豚（Phocoena Phocoena）中的EOX浓度高于他们吃的鱼中的EOX。有人认为，海洋哺乳动物中存在的EOX通过波罗的海的海洋食物链积累。在沉积物中检测到的EOCI的大部分和生物样品被未识别的组合占据。有必要分析波兰环境中EOX残留物中的各个化合物，以调查其来源并评估对野生动植物的影响，以及居住在波兰的人们。它得出的结论是，许多卤代组合都分布在波兰环境中，并且该化学污染发生在格丹斯克湾和波罗的海湾的沿海地区。
