摘要:
对镇江市金山湖18个采样点的水体As、Pb、Cu、Zn、Cr以及Cd元素含量进行为期1年的监测，并通过单因子以及内罗梅综合指数，对金山湖水体重金属风险进行综合评价。结果表明：（1）金山湖18个采样点水体As、Pb、Cu、Zn、Cr以及Cd元素含量平均值分别为6.02、2.15、3.45、6.42、1.57 和1.05 μg/L。6种重金属平均值均小于地表水环境质量标准的三类标准。此外，金山湖水体中As元素含量小于太湖水体，但高于其他湖泊；Pb、Zn元素含量小于文献报道的其他湖泊水体。Cu与Cd元素则介于文献报道的其他湖泊水体重金属含量的之间。方差分析结果表明，Cu和Cd元素含量在4个季节具有显著的差异（P＜0.01），而其余重金属元素含量在4个季节无显著差异，表明季节对金山湖水体Cu和Cd元素影响较大，而其他元素含量受季节影响较小。（2）对金山湖水体重金属进行单因子评价结果表明，金山湖水体18个采样点As、Pb、Cu、Zn、Cr以及Cd元素的单因子指数值均在0.7以下，表明水体尚未受到以上6种金属元素的影响，总体均表现为清洁状态。（3）内梅罗综合指数值表现为As＞Pb＞Cr＞Cd＞Zn＞Cu。从空间角度来看，18个采样点的内梅罗综合指数值均小于0.7，表明金山湖水质较为优良，基本不受重金属污染的影响，这与单因子评价结果一致。以上调查及评价结果可为金山湖水体重金属的防治提供基础资料和数据支撑。
Abstract:
The contents of As, Pb, Cu, Zn, Cr and Cd in 18 sampling sites of Jinshan Lake in Zhenjiang City were monitored for one year, and the risk of heavy metals in Jinshan Lake was evaluated comprehensively by single factor index and Nemerow composite index.The results showed that:（1) The average contents of As, Pb, Cu, Zn, Cr and Cd in 18 sampling sites of Jinshan Lake were 6.02, 2.15, 3.45, 6.42, 1.57 and 1.05 ug/L, respectively.The average values of six heavy metals were all lower than the Class three of surface water environmental quality standards.In addition, the content of As in Jinshan Lake was lower than that in Taihu Lake, but higher than that in other lakes; the content of Pb and Zn in Jinshan Lake was lower than that in other lakes reported in literature.The contents of Cu and Cd were between those of other lakes reported in the literature.The results of variance analysis showed that the contents of Cu and Cd had significant difference in the four seasons（P < 0.01), while the contents of other heavy metals had no significant difference in the four seasons, indicating that the season had a greater impact on the contents of Cu and Cd in Jinshan Lake waters, while the other elements were less affected by the seasons.(2) The single factor evaluation results of heavy metals in Jinshan Lake water showed that the single factor index values of As, Pb, Cu, Zn, Cr and Cd in 18 sampling sites were all below 0.7, indicating that the water body had not been affected by the above six metal elements, and the water body was generally in a clean state.(3) The value of Nemerow composite index was As＞Pb＞Cr＞Cd＞Zn＞Cu.From the spatial point of view, the Nemerow composite index values of 18 sampling points were less than 0.7, which indicated that the water quality of Jinshan Lake was better and was not affected by heavy metal pollution, which was consistent with the results of single factor evaluation.The above investigation and evaluation results could provide basic information and data support for the prevention and control of heavy metals in Jinshan Lake.
