In this study Sydney rock oysters (S. glomerata) from six major sea ports of NSW, Australia were used as bioindicators to assess the distribution and levels of trace element accumulation in the ports. Substantial enrichment of Cu, Pb and Zn in the oysters of the sea ports were detected when compared to their background samples and the US Environmental Protection Agency (USEPA) provisional tolerable intake standard. Enrichment of As, Al, Fe, Mn, Br, Sr were also found in the oysters at the port areas. The bioconcentration ratios of the trace elements illustrated significant Fe, Cu, Zn, As, Mn, Al, Pb and Cr accumulation in S. glomerate. The biota sediment accumulation factor suggested Cu, Mn and Zn accumulation at two of the ports (Port Yamba and Botany), indicating availability of these metals in the oysters as strong metal accumulators. In addition, integrated metal contamination illustrated notable Fe, Zn, Cu and Al contamination at port environment, whereas cluster analysis portrayed interconnection between the contaminants and the study sites.
在这项研究中，澳大利亚新南威尔士州六个主要海港的悉尼岩蚝 (S. glomerata) 被用作生物标志物，以评估港口中微量元素积累的分布和水平。与背景样本和美国环境保护署 (USEPA) 的暂定可耐受摄入量标准相比，发现海港口的牡蛎中 Cu、Pb 和 Zn 大量富集。在港口地区的牡蛎中也发现了 As、Al、Fe、Mn、Br、Sr 的富集。微量元素的生物浓缩比表明 S. glomerata 中存在显著的 Fe、Cu、Zn、As、Mn、Al、Pb 和 Cr 积累。生物群-沉积物积累因子表明两个港口（Yamba 港和 Botany 港）的 Cu、Mn 和 Zn 积累，表明这些金属在牡蛎中作为强金属积累者是可用的。此外，综合金属污染表明港口环境中存在显著的 Fe、Zn、Cu 和 Al 污染，而聚类分析则表明污染物与研究地点之间存在关联。
