| 摘 要： | 根据胶州湾海水和表层沉积物样品中重金属含量的分析，探讨了胶州湾的污染现状和发展趋势。将海水和表层沉积物中的重金属含量与该区周边岩石的重金属含量及国家环境标准对比研究表明，胶州湾海水中Cu和Cd含量符合国家一类海水标准，Pb的污染最为严重。胶州湾东部表层沉积物中的Cd、Hg、Pb的含量均超过一类沉积物的国家标准。其主要污染区位于大港至李村河口一带，污染源主要来自陆源污染物，并由河流排出入海所致。胶州湾中部的重金属含量低于国家标准，说明环境状况良好。 |

| Abstract: | Based on the analysis of contents of heavy metals in sea water and the surface sediment samples, the authors studied the current state and development tendency of the heavy metal contamination in the Jiaozhou Bay. Compared the heavy metal contents of seawater and surface sediment with the values of the tate environmental standards. Cu and Cd contents in the sea water of Jiaozhou Bay accorded with the first-class standard, but Pb runs much beyond the standard. In the surface sediment samples from the east of the bay ,the contents of Cd, Hg and Pb were much higher than the the state first-class standard, and the area from Dagang to Licun estuary was the main contaminated region. The contaminant metals mainly comes from terrigenous materials, which were carried into the sea by rivers. In the central part of the Jiaozhou Bay the environment conditions were good, because the heavy metal concents were lower than the state standards. |
