Distribution Characteristics and Ecological Risk Assessment of Heavy Metals in Soil Around Aquaculture Farms
Based on the soil around the chicken farm,pig farm and cattle farm,content analysis,correlation analysis and ecological risk as-sessment of 8 kinds of heavy metals were analyzed.Results showed that:the content of heavy metal in soil around the farm was Mn>Zn>Cr>Pb>Cu>As>Cd>Hg.The heavy metal pollution of the soil around the chicken farm needed to be paid enough attention.The soil around the cattle farm needed to pay attention to the pollution of Hg.There was a significant correlation between the heavy metals,indicating that they might come from the same pollution sources.The potential ecological risk of heavy metals in the soil around the farm was:Hg>Cd>As>Pb>Cu>Zn>Cr>Mn.The soil around the farm was in the middle potential ecological risk,so it is necessary to pay enough attention to the risk of heavy metals in the soil.
