To investigate the heavy metals pollution degree of in the soil around an electroplating factory and evaluate the health risk caused by contaminated soil. Based on soil in the vicinity of an Electroplating factory in JiaXing, soil in different horizontal distance and depth below wind direction direction of research region were sampled, and the heavy metal content were measured. The heavy metal pollution status was analyzed by using index of Geoaccumulation and health risk assessment. The results showed that the average index of Geoaccumulation (Igeo) of the 7 heavy metal (Cr, As, Pb, Ni, Cu, Zn, Cd) in the region was higher than 5, and it was at the extremely serious pollution level. The content of As in the middle part soil (1020 cm) reaches the maximum of 2109. 25mg/kg, As pollution is relatively serious, and the average value exceeds the limit by 119.39 times. Cd is the least contaminate, but still reaches a medium-pollution. EDI non-carcinogenic exposure to As was greatest in children when ingestion of oral food. Conclusion Health risk assessment indicates of As intake by oral food has far exceeded the warning value, and there exist a high Risk of cancer, while Ni has a potential Risk of cancer. Therefore, we should pay great attention to these two heavy metal. and prevention and treatment of the polluted soil.
