The investigation and analysis of soil heavy metal pollution around one of the battery manufacturer in Tai’an | 泰安市某蓄电池生产企业周围土壤重金属污染现状调查与分析

صينى. 随着经济的迅猛发展和人们对电动车的需求，铅蓄电池生产企业越来越多。铅蓄电池的生产可能造成周围土壤的重金属污染。土壤受重金属污染后，不仅会退化土壤肥力，使农作物产量下降，而且可能通过食物链的传递危害人类健康。因此，土壤重金属污染问题受到越来越多的重视。泰安市世华电缆电池有限公司以生产铅酸蓄电池及零部件为主，为了解世华电缆电池有限公司周围土壤重金属污染情况，以该公司周围一定距离土壤样品为研究对象，在野外采样和实验室分析的基础上，评价企业周围土壤受Cu、Zn、Pb三种重金属的污染程度。结果表明，该公司周围环境中部分土壤样品中Cu、Zn、Pb含量与土壤环境背景值相比有显著提高（P0.05），但周边土壤中三种主要重金属的污染均未超过国家土壤环境质量二级标准，污染等级为清洁，公司对周围土壤重金属污染影响较小。

Lead battery production may cause the soil heavy metal pollution. Soil by heavy metal pollution, will not only cause the degradation of soil fertility, make the crop yields down, but also do harm to human health through the food chain transfer. Therefore, soil heavy metal pollution has been paid more and more attention. Tai’an shihua cable battery limited company mainly produce lead-acid batteries and spare parts. In order to understand of heavy metal pollution around Taian shihua cable battery limited company, the soil samples were collected around the company at uariable distances, on the base of field sampling and laboratory room analysis, evaluation of the soil Cu, Zn, Pb pollution was made. The results show that some soil sampies of the company Cu, Zn, Pb concentrations exceed background values of soil environment of Shandong Province, but the three main heavy metals Cu, Zn, Pb contamination around the soil did not exceed the national environmental quality standards, pollution levels for clean, the company have little influence on the surrounding soil heavy metal pollution.
