Selected trace elements (As, Cr, Zn, Cu, Cd, Co, Pb and Ni) in 76 surface sediment samples collected from the rivers and the intertidal zone of Jiaozhou Bay (JZB) were evaluated to assess their environmental background values in the JZB catchment. Overall, the sediment quality in the area meets the China Marine Sediment Quality criteria. The background values (ranges) of the elements As, Cr, Zn, Cu, Cd, Co, Pb and Ni were, respectively, 8.28 (4.10-12.46), 67.96 (38.40-97.52), 56.80 (16.42-196.51), 19.13 (5.71-64.06), 0.10 (0.02-0.42), 6.51 (2.08-20.40), 17.97 (12.26-55.84) and 20.69 (10.43-30.95)mg/kg. The background values of most of the trace elements were lower than those in Chinese soil, the upper continental crust, global shales and global preindustrial sediments. The results may assist in defining future coastal and river management measures specifically targeted at monitoring trace element contamination in the JZB catchment.
对从胶州湾（JZB）河流和潮间带采集的76个表层沉积物样本中的选定微量元素（砷、铬、锌、铜、镉、钴、铅和镍）进行了评估，以确定它们在JZB集水区的环境背景值。总体而言，该区域的沉积物质量符合中国海洋沉积物质量标准。元素砷、铬、锌、铜、镉、钴、铅和镍的背景值（范围）分别为8.28（4.10 - 12.46）、67.96（38.40 - 97.52）、56.80（16.42 - 196.51）、19.13（5.71 - 64.06）、0.10（0.02 - 0.42）、6.51（2.08 - 20.40）、17.97（12.26 - 55.84）和20.69（10.43 - 30.95）mg/kg。大多数微量元素的背景值低于中国土壤、上地壳、全球页岩和全球工业化前沉积物中的背景值。这些结果可能有助于确定未来专门针对监测JZB集水区微量元素污染的沿海和河流管理措施。
