Analysis of Heavy Metal Pollution Sources in Different Farmland Soils
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.
