摘要
于2000年对渤海湾主要河口及海岸带部分区域与环境毒理学相关的污染特征进行了一次探查分析。结果表明,环渤海湾河口区域部分水质和底泥的环境污染程度属中度或严重污染状态。其中,有些采样点个别重金属元素和有机污染物超过有关环境标准的状况较严重,如在海河口、辽河口及黄河口的个别样品中,有害元素铬(Cr)、镉(Cd)、镍(Ni)、汞(Hg)、砷(As)、铅(Pb)等的含量超标数倍以上,总可检出有机物达200余种,污染物可能主要来源于各类生产单位的废水排放。
The status of pollutant characters related to environmental toxicology in main estuaries and coastal zones of Bohai Bay were investigated in 2000. It was shown that the environmental quality of some water and sediments belongs to middle-high level pollution in the estuary water environment. The pollution of some heavy metal elements and organic pollutants is serious compared with that of environmental criterion in some sampling sites. For instance, in some estuary sites of the Haihe River, the Liaohe River and the Huanghe River, the contents of chromium, cadmium, nickel, mercury, arsenic and lead etc. exceed by several times compared with the criterion. There are more than 200 organic compounds being detected, which mainly come from industrial emission and drainage.
