通过对胶州湾潮间带29个表层沉积物样品中Al和Cu、Pb、Zn、Cr、Cd、As等重金属含量的分析，评价了胶州湾潮间带表层沉积物中Al和Cu、Pb、Zn、Cr、Cd、As的污染程度。结果表明，该地区沉积物的总体质量已明显受到微量金属污染的影响。地积累指数和富集因子值表明，该地区基本未发生Cr、Cu污染，仅个别站点受到As污染，部分地区受到Cd、Pb、Zn污染。主成分分析表明，铜，铅，锌，镉来自人为输入和铬，砷，铜，锌受自然风化过程的影响。Cu和Zn可能来自自然和人为来源。JZB东北部的污染高于海湾的其他区域。
The major (Al) and trace metal (Cu, Pb, Zn, Cr, Cd, and As) concentrations in 29 surface sediment samples from the intertidal Jiaozhou Bay (JZB) are evaluated to assess the contamination level. The results show that the overall sediment quality in the area has been obviously impacted by trace metal contamination. The geoaccumulation index and the enrichment factor values indicate that no Cr or Cu contamination has occurred on the whole, only a few stations have been polluted by As, and some areas have been polluted by Cd, Pb, and Zn. Principal component analysis suggests that the Cu, Pb, Zn, and Cd are derived from anthropogenic inputs and that Cr, As, Cu, and Zn are influenced by natural weathering processes. Cu and Zn may originate from both natural and anthropogenic sources. The contamination in the northeastern JZB is higher than that in other areas of the bay.
