水环境受到重金属污染的影响。以中国东部浅水湖泊为研究对象，探讨了环境因素和人类活动对沉积物中重金属分布和风险的影响。采用电感耦合等离子体发射光谱法测定了沉积物中Cd、Cr、Cu、Ni、Pb、Se和Zn的含量。Igeo法显示，湖泊沉积物中Cr、Cu、Pb和Zn均为中度污染，EF法显示Cd和Se在湖泊中明显富集。除高邮湖、洪湖、鄱阳湖和微山湖外，其余大部分湖泊的重金属含量均处于中等风险水平。RI法显示洞庭湖和鄱阳湖存在极高的风险。镉被发现比其他金属造成更高的风险水平。重金属含量与总碳、总氮、总磷、总硫含量呈显著正相关。国内生产总值很好地反映了人类活动。区域生产总值、一、二次产业生产总值与Cu、Pb浓度均存在显著相关关系，说明人类活动对不同重金属污染的影响不同。国内生产总值指数被认为是湖泊重金属污染背后的驱动力。
The aquatic environment is affected by heavy metal pollution. This study was conducted to test the hypothesis that environmental factors and anthropogenic activities influence the distributions and the risks posed by heavy metals in surface sediments in shallow lakes in eastern China, which is an area affected by rapid urbanization, industrialization, and population growth. Total Cd, Cr, Cu, Ni, Pb, Se, and Zn concentrations in sediment samples were determined using inductively coupled plasma optical emission spectrometry. TheIgeoshowed that sediments in the lakes were moderately polluted with Cr, Cu, Pb, and Zn, and the EF method showed that Cd and Se were significantly enriched in lakes. The heavy metals were found to pose moderate risks in most of the lakes, except for Gaoyou Lake, Honghu Lake, Poyang Lake, and Weishan Lake. The RI method indicated that very high risks were posed in Dongting Lake and Poyang Lake. Cd was found to pose much higher levels of risk than the other metals. Significant correlations were found between the heavy metal concentrations and the total carbon, nitrogen, phosphorus, and sulfur concentrations. The gross domestic product represented anthropogenic activities well. The gross domestic product of an area and the gross domestic products of primary and secondary industries in an area all had significant relationships with the concentrations of Cu and Pb, indicating that anthropogenic activities have different impacts on pollution with different heavy metals. The gross domestic product index was found to be a driving force behind the pollution of lakes with heavy metals.
