Summary:This study takes the soil around a plastic metal factory in Jiaxing as the research object, and measures the wind direction under the northwest wind in the autumn. The Hg, Cd, As, Ni in the soil samples at different horizontal distances and depths (0-30cm) The contents of seven elements of Pb, Cu and Cr were evaluated by the geoaccumulation index method, the Nemero pollution comprehensive index method and the potential ecological risk index evaluation method. The number of samples with severe pollution levels calculated by the Nemero pollution comprehensive index method accounted for 85.71% of the total. Using the potential ecological risk index evaluation method, it is concluded that the single ecological risk of Cd and Cr is very strong and above, and the samples account for 100% of the total sample. The soil accumulation index method was used to analyze the pollution of heavy metals: Cd>Hg>Ni>Cu>As, Cr>Pb. The results show that the ecological risk assessment results under the combined action of various heavy metals are not optimistic, and the potential ecological risks are extremely heavy.
