摘要

摘要:
为揭示湖北网湖沉积物重金属污染特征，采用空间插值法、主成分分析法和地累积指数对其污染特征、来源识别及生态风险状况进行分析。结果表明：5种重金属的平均浓度从高到低依次为Zn>Cr>Cu>Pb>Cd，且浓度均超过湖北省土壤背景值；Pearson相关性分析表明，Zn与Cd、Pb浓度呈正相关（P<0.05)，Cu与Zn、Cr浓度呈负相关（P<0.05)。主成分分析发现，主成分1由Pb、Cd、Zn构成，主要来源于河流运输和农业活动影响；主成分2由Cr和Cu构成，主要来源于矿物风化等自然背景和工业活动及水产养殖等人类活动污染影响。地累积指数结果显示，网湖沉积物中重金属处于低风险状态，但Cd和Cu达到中度污染，为主要污染物，应予以关注。

Abstract:
To reveal the characteristics of heavy metal pollution in the sediments of Wanghu Lake in Hubei Province, the methods of spatial interpolation, principal component analysis, and geo-accumulation index were used to investigate the pollution features, source identification, and ecological risk status of heavy metal pollution. The results showed that the average concentration of five heavy metals decreased in the order of Zn>Cr>Cu>Pb>Cd, and all of them exceeded Hubei soil background values. Pearson correlation analysis revealed a positive correlation (P<0.05) between Zn and Cd, Zn and Pb, and a negative correlation (P<0.05) between Cu and Zn, Cu and Cr. Principal component analysis revealed that principal component 1 was consisted of Pb, Cd, and Zn, which were primarily influenced by river transportation and agricultural activities; principal component 2 was consisted of Cr and Cu, which were mainly affected by natural background such as mineral weathering and pollution from human activities such as industrial activities and aquaculture. The geo-accumulation index results suggested that heavy metals in Wanghu Lake were in a low risk condition, although Cd and Cu reached moderate pollution and were the major pollutants that should be monitored.
