本文报道了珀斯南部沿海沃茨沉积物和贻贝中有机污染物的调查结果。有机磷和有机氯农药，多氯联苯，脂肪族和多环芳烃和有机锡化合物进行了分析，表层（顶部20毫米）沉积物从175个网站和贻贝组织从35个网站超过500平方公里的面积。记录的农药、多氯联苯和脂肪烃的可检测浓度约为1000 ppm。5%的沉积物和10%的贻贝。污染一般局限于航运设施和码头内或紧邻这些设施和码头的地区。相比之下，污染的沉积物和贻贝与多环芳烃和有机锡化合物，特别是三丁基锡，是广泛的整个研究区域。污染程度最高的地区是港口和船只停泊区以及科伯恩湾东侧的沿着。与澳大利亚和海外类似研究的结果相比，这些沃茨的沉积物和贻贝一般没有受到杀虫剂、多氯联苯或碳氢化合物的严重污染。相比之下，沉积物和贻贝中三丁基锡的浓度升高是澳大利亚记录的最高浓度之一，再加上已知的这种化合物对海洋动物的毒性，引起了人们的严重关切。在新腹足类，Thais orbita，从研究领域收集的高频率的性畸变强调了这一问题。
The results of a survey of organic pollutants in the marine sediments and the common mussel, Mytilus edulis, from the southern metropolitan coastal waters off Perth are presented. Organophosphorus and organochlorine pesticides, polychlorinated biphenyls, aliphatic and polycyclic aromatic hydrocarbons and organotin compounds were analysed in surficial (top 20 mm) sediments from 175 sites and in mussel tissue from 35 sites over an area of 500 km2. Detectable concentrations of pesticides, polychlorinated biphenyls and aliphatic hydrocarbons were recorded at approx. 5% of the sediment sites and 10% of the mussel sites. Contamination was generally confined to areas within or immediately adjacent to shipping facilities and marinas. By contrast, contamination of sediments and mussels with polycyclic aromatic hydrocarbons and organotin compounds, particularly tributyltin, was widespread throughout the study area. Areas of highest contamination occurred in harbours and boat mooring areas and along the eastern side of Cockburn Sound. Comparisons with the results of similar Australian and overseas studies indicate that, in general, sediments and mussels from these waters are not significantly contaminated with pesticides, polychlorinated biphenyls or hydrocarbons. In contrast, elevated concentrations of tributyltin in the sediments and mussels are amongst the highest recorded in Australia and, coupled with the known toxicity of this compound to marine animals, are cause for major concern. The high frequency of imposex in the neogastropod, Thais orbita, collected from the study area underlines this concern.
