烟台港倾倒区表层沉积物重金属的富集特征及风险评价
Enrichment and risk assessment of heavy metals in surface sediments of Yantai Port Ocean Dumping Site
摘要
Abstract
Based on the monitoring data of Yantai Port Ocean Dumping Site from 2001 to 2011, the contents and distribution of heavy metals in surface sediments were analyzed, and the enrichment degree and potential ecological risk were assessed using Igeo and ERI. It was found that the concentrations of heavy metals in the surface sediments were relatively low and the spatial distribution varied slightly. Compared with the background values of the Yellow Sea, cadmium and copper appeared a certain extent accumulation. ERI assessment indicated that the ecological risk of year 2011 was slight and the annul variation trend was 2008>2006>2009>2011>2001. Additionally, cad-mium and mercury were key factors of the potential ecological risk in the dumping site.关键词
