粤北地区铅锌矿采选业土壤污染特征研究

A Study on Soil Pollution Characteristics of Lead-zinc Mine Mining Industry in Northern Guangdong Province

摘针对粤北地区铅锌矿采选业的生产工艺、产污环节及对土壤及地下水污染来源的相关分析,并经过典型铅锌矿采选企业采样分析,明确威胁矿区及周边土壤和居民的污染物及迁移特性,从最佳环境管理技术及土壤保护与综合治理两方面提出建业,为粤北地区铅锌矿采选业的风险管控、土壤保护与综合治理提供参考依据。

First of all, production technology, pollution-producing links and sources of soil and groundwater pollution in lead-zinc mining industry in northern Guangdong Province are analyzed. Secondly, through a sampling analysis on typical lead-zinc mining enterprises, pollutants threatening mining areas, surrounding soil and residents and their migration characteristics are clarified. Thirdly, suggestions are proposed from two aspects of optimal environmental management techniques and soil protection and comprehensive governance, in an effort to provide guidance for risk management, soil protection and comprehensive management of lead-zinc mining industry in northern Guangdong Province.
