Thirteen sites in Deception Bay, Queensland, Australia were sampled three times over a period of 7 months and assessed for contamination by a range of heavy metals, primarily As, Cd, Cr, Cu, Pb and Hg. Fraction analysis, enrichment factors and Principal Components Analysis-Absolute Principal Component Scores (PCA-APCS) analysis were conducted in order to identify the potential bioavailability of these elements of concern and their sources. Hg and Te were identified as the elements of highest enrichment in Deception Bay while marine sediments, shipping and antifouling agents were identified as the sources of the Weak Acid Extractable Metals (WE-M), with antifouling agents showing long residence time for mercury contamination. This has significant implications for the future of monitoring and regulation of heavy metal contamination within Deception Bay.
在澳大利亚昆士兰州的迪钦贝湾，13 个地点在 7 个月的时间里被采集了 3 次，以评估一系列重金属（主要是砷、镉、铬、铜、铅和汞）的污染情况。为了确定这些关注元素及其来源的潜在生物可利用性，进行了分馏分析、富集因子和主成分分析-绝对主成分得分（PCA-APCS）分析。汞和碲被确定为迪钦贝湾中富集程度最高的元素，而海洋沉积物、航运和防污剂被确定为弱酸可提取金属（WE-M）的来源，防污剂显示出汞污染的长时间停留时间。这对未来监测和监管迪钦贝湾重金属污染具有重要意义。
