电镀厂周边农田土壤重金属污染特征及综合评价

摘要：本文对某电镀厂南北两侧农田土壤进行采样分析，结合现场调查，查明重金属污染原因。由于企业内部管理缺失，在雨季地表径流作用下，重金属从电镀厂大门、沟渠等迁移至农田。其间通过单因子污染指数评价和潜在生态危害指数评价，对污染区域进行分级，为后续监测提供依据，也为污染土壤的风险管理奠定基础。

Abstract： This paper conducts sampling analysis on the soil of farmland in the south and north sides of a certain electroplating plant， combined with on-site investigation， to identify the causes of heavy metal pollution. Due to a lack of internal management within the enterprise， heavy metals migrate from electroplating plant gates， ditches， etc. to farmland under the influence of surface runoff during the rainy season. During this period， the polluted areas are graded through single factor pollution index evaluation and potential ecological hazard index evaluation， providing a basis for subsequent monitoring and laying a foundation for risk management of contaminated soil.
