摘要
根据《土壤环境质量标准》和《农用污泥中污染物控制标准》,采用单因子评价方法,对辽河流域河流底泥中重金属含量进行分析和评价。结果表明,整体上辽河流域河流底泥重金属污染较轻,部分水系河流底泥重金属含量较高,8项重金属元素在不同水系河流底泥中都存在部分元素超标现象。
According to Soil Environment Quality Standard and Control Standard for Pollutants in Agricultural Used Sludge,using single factor evaluation method,heavy metal contents in Liaohe River basin sediments were analyzed and evaluated.The results show that Liaohe River is less polluted on the whole,but still high in the heavy metal contents in some parts of the river sediment,and eight heavy metal elements all exceed in river sediments in different river systems.
