“长株潭”地区湘江底泥重金属含量调查研究

摘要

The investigation on heavy metal current content of the sediment of Xiangjiang River in Changzhutan area was conducted by analysis of its heavy metals such as zinc , copper, cadmium, chromium, lead, mercury, and manganese .The content of heavy metals in sediment samples was compared with that of soil environmental quality standards , sewage discharged into the city sewer water quality standards and sanitary standard for drinking water in order to find the pollution severity of the heavy metals in Xiangjiang River in Changzhutan section .According to the survey results, three suggestions were that the reduction of waste water containing heavy metals in Xiangjiang River Changzhutan section was collected , relevant departments should pay close attention to changes in the content of heavy metals , and the content of heavy metals in river sediment surface should be repaired .%通过调查分析湘江“长株潭”段表层底泥的锌、铜、镉、铬、铅、汞、锰等重金属含量，将底泥样品中重金属的含量分别与土壤环境质量标准、污水排入城市下水道水质标准、以及生活饮用水卫生标准中重金属含量进行比较，从而发现重金属在湘江“长株潭”段的污染严重程度。根据调查结果分析，对湘江“长株潭”段底泥重金属污染问题提出减排含重金属废水，有关部门应关注底泥重金属含量变化，和修复河床表层重金属含量高的底泥等建议。
