上海市闵行区部分工业企业地下水中锰含量研究

Research on Concentration of Manganese in Groundwater of Some Industrial Enterprises in Minhang District,Shanghai

指出了锰作为《地下水中质量标准》(GB/T 14848-2017)中的一般化学指标,其含量如果过高会为人体健康带来风险。基于此,探讨了上海市闵行区中地下水锰的背景值,并对比了闵行区部分工业企业地下水采样数据。结果表明:上海市地下水中锰属高背景值环境,但以化学原料和化学制品制造业为代表的工业企业生产仍会造成地下水中锰含量的进一步升高,需加强管理。同时计算了地下水中锰的风控值,根据计算结果,提出了建议:进一步加强对于地下水开发利用尤其是限制饮用的管控,同时关注建设开发期建筑工人可能存在的暴露风险。

As general chemical item of Standard for Groundwater Quality(GB/T 14848-2017),manganese in groundwater needs to be concerned if concentration is over high.This paper introduces background level of manganese in groundwater of Minhang District,Shanghai and compares manganese concentration in groundwater of some industrial enterprises according to testing data from qualified labs.Results shows that though background level of manganese in groundwater is high,industrial production such as chemical industry will increase concentration of manganese.This paper also calculated risk control of manganese in groundwater.According to the risk control result,it is suggested that groundwater exploitation,especially groundwater intake,should be strictly controlled and potential exposure of construction workers to groundwater with high concentration of manganese should be concerned.
