摘要
本研究对吴兴区农田土壤重金属污染现状和来源进行了调查,明确了其空间分布特征并确定了其在区域尺度上的主要来源.通过测定每个土壤样品中重金属的浓度,以及土壤中重金属的空间分布和PMF来源分析,本文分别对吴兴区不同农田土壤重金属的分布进行了探讨,揭示了土壤重金属的主要来源.结果表明,研究区内土壤重金属大部分呈轻度污染.然而,一些区域的土壤中镉和铬的含量达到中度至重度污染水平.本研究为下一步的土壤修复提供了方法依据.
Abstract
A survey was conducted on the current situation and sources of heavy metal pollution in farmland soil in Wuxing District,clarifying the spatial distribution characteristics and determining its main sources at the regional scale.By measuring the concentration of heavy metals in each soil sample,and analyzing the spatial distribution and PMF sources of heavy metals in soil,the distribution of heavy metals in different farmland soils in Wuxing District was explored,revealing the main sources of soil heavy metals.The results indicate that most of the soil heavy metals in the study area are mildly polluted.However,in some regions,soil cadmium and chromium levels have reached moderate to severe pollution levels.This study provides a methodological basis for the next step of soil remediation.
