| 摘 要： | 根据对环渤海湾诸河口实地采集的12个水样进行的重金属、砷、总氮和总磷含量分析，发现环渤海湾诸河口水污染严重，多超过地表水V类标准，主要污染物质为Hg、N和P，其他污染物含量均在地表水H类标准以内。其中海河口处的Hg含量在20年间增加了10倍左右。诸河口水体中N和P含量均达到水体富营养化危险负荷，可见陆源污染是渤海湾富营养化日趋严重、赤潮日趋增多的主要原因。 |

| Abstract: | Twelve water samples collected in the estuaries around Bohai Bay from field investigation have been analyzed for their concentrations of heavy metals, arsenic, TN and TP. It shows that the estuaries around Bohai Bay have serious water pollution, most of them are exceeded Standard V of the Environmental Quality Standard for Surface Water and the main pollutants are Hg, N and P the concentrations of the other pollutants are all below Standard II of the Environmental Quality Standard for Surface Water. Among them, the Hg concentration in Haihe estuary is increased to 10 times as that of 20 years ago. The concentrations of N and P in estuaries are all reached to the dangerous loads of eutrophication in waters, which indicates terrestrial pollution is the main reason for the growing eutrophication and red tide in Bohai Bay. |
