摘要
为了分析鄱阳湖悬浮物重金属的潜在生态危害,实地采集水样分析了悬浮物重金属的含量及污染特征。根据分析成果,采用Hakanson潜在生态危害指数法评价了鄱阳湖悬浮物重金属污染程度。分析评价结果表明:鄱阳湖南湖区的悬浮物重金属潜在生态危害大于北湖区;具有潜在生态危害的主要重金属是Cd和Cu;鄱阳湖大部分区域已达中度以上危害程度,轻度危害水平区域只占1/8;悬浮物重金属的赋存含量不仅与其赋存方式有关,与元素本身也有关联性。
In order to analyze potential ecological risk of heavy metals in suspended solids in Poyang Lake, in - situ water was sampled and heavy metal contents in suspended solids as well as their pollutant characteristics were analyzed. Based on the analyzed results, heavy metal pollution of Poyang Lake is assessed by Hakanson ecological risk index. The analysis results show that the heavy metal pollution in suspended solids in southern area of the Poyang Lake is heavier than that in northern area of the lake ; the main potential heavy metals are Cd and Cu; the most area of the lake is moderately polluted, only 1/8 area is lightly polluted. The heavy metal contents in suspended solids are not only related with their occurrence mode, but also related with metal elements themselves.
