毕节地区土法炼锌废弃场地风险评估

Risk Assessment on Abandoned Traditional Smelting Zinc Sites in Bijie Prefecture

为加强贵州省重金属污染的防治,对毕节地区土法炼锌废弃场地进行了风险评估。结果表明,赫章县三岔河流域上游妈姑镇的黑泥和天桥村炼锌废渣和废弃场地,及六冲河流域上游的野马川镇的尖山村炼锌废渣和废弃场地是毕节地区重金属污染的主要污染源,镉、铅、锌在土法炼锌区及周边农村社区存在很高的人体健康和环境污染风险。

The risk assessment of abandoned traditional smelting zinc sites in Bijie prefecture was carried out to strengthen control of heavy metal pollution.The results showed that the waste residue and abandoned area from Heini,Tianqiao and Jianshan abandoned traditional smelting zinc sites are the main sources of heavy metal pollution in Bijie prefecture,and there is a risk of cadmium,lead and zinc to harm human health and pollute environment in the abandoned traditional smelting zinc sites and surrounding rural communities of the abandoned traditional smelting zinc sites.
