根据2003年对胶州湾东部和青岛前海2008年奥运赛场海域表层沉积物中重金属、有机碳和硫化物的调查结果表明:研究区的重金属(As除外)高含量主要分布在团岛污水处理厂,大港出口北侧至李村河口沿岸一带。作者通过与胶州湾周围岩体、地层和松散沉积物中重金属的平均含量比较以及重金属与环境因子有机碳、硫化物的相关分析,证明了研究区的重金属污染主要来自于工业和生活污水的排放,并且重金属与硫化物的物源不尽相同。作者发现由于胶州湾的潮流作用模式使胶州湾东部排入的污染物向西扩散的可能性削弱,是胶州湾东部污染严重的一个自然因素。同时由于胶州湾东部的部分污染物经由沦口水道搬运到青岛前海的退潮三角洲区域而出现局部高值区,其中沉积物中的Cr和Cu已有超标现象,应引起重视。
According to the survey of surface sediments of Jiaozhou Bay and Qingdao adjacent coastal sea where is racing sailboat field of 2008 Olympic, including heavy metals organic carbon and sulfide. It shows that the high value (except As) mainly distributes these areas: Tuandao Sewage Disposal Company, the north of port to the bay out of Licun River. By comparing with surround rocks, strata and sediment, and the correlation with organic cardon and sulfide, the heavy metals (except As) are mainly from three industrial wastes and living sewage, and the sources are not the same with sulfide. The author found the tidal mode of Jiaozhou Bay weakens the possibility that the pollutant discarged from the eastern Jiaozhou Bay diffusing to west, which is the key natua factor to cause the had pollution in eastern bay. At the same time, the pollutants of Jiaozhou Bay are being carried to ebb tide delta of Qingdao adjacent coastal sea passed by Cangkou Channel and appearing comparative high value area, Cr and Cu appeared over run national marine sediment first standard, it mnst be paid attention.
