- Abstract:
- The concentrations of soil heavy metals in water-level-fluctuating zone are directly associated with water safety and human health. In this study, the concentrations of Cu, Cr, Ni and Zn in water-level-fluctuating zone soils of the Three Gorges Reservoir (TGR) area were determined, and their influencing factors and characteristics of distribution were studied. The results showed that the total concentrations of Cu, Zn, Cr and Ni in the water-level-fluctuating zone soil of Xiaojiang river in the TGR area were 28.69 mg/kg, 126.03 mg/kg, 57.20 mg/kg and 27.91 mg/kg. Correlation analysis showed that Ni, Cr, Cu were significantly affected by soil properties. There were significantly positive or positive relations between organic matter, coarse cosmid, cosmid and total Ni, total Cr, total Cu. There were positive relations between silt and total Cr, total Cu. There were negative relations between sand and total Ni, total Cr, and total Cu. Stepwise regression analysis showed that Cr, Ni are mainly affected by coarse cosmid content. Cu is mainly affected by sand content. ANOVA showed that there were significant differences of total concentrations of soil heavy metals in each section of the water-level-fluctuating zone, where the concentrations of soil heavy metals increased gradually from the upper stream to the middle and decreased in the downstream. There was no significant difference in their distributions at different altitudes.
