| description | This paper made the research on the heavy metal pollution situations in three areas of contaminated sites in Weinan city, including reactor, pollution source and administrative area. The results show that the contaminated sites are polluted at different levels, mainly Hg and As. The evaluation results of nemerow indexes demonstrate that the comprehensive pollution index of soil in reactor area is polluted seriously, the comprehensive pollution index of soil in pollution source area belongs to mild pollution and middle pollution and the comprehensive pollution index of soil in the administrative area belongs to clean pollution. The potential ecological risk of polluted site was evaluated by ecological hazard index method. The results show that the total potential ecological harm of soil in reactor belongs to strong grade. The potential ecological harm of Hg is strong, the potential ecological harm of Cd belongs to the medium level, As of 80% point belongs to the strong level, and As of 20% of the points belongs to the middle level. The potential ecological hazards of Hg and Cd are moderate. The potential ecological risk of Hg is strong, the potential ecological risk of Cd belongs to the middle level and the rest heavy metals are in the safety range. Moreover, the total potential ecological harm of soil is in the safety margin. |
