The research focused on assessing the risk to human health resulting from the content of selected Cr, Co, Mn, Cu, Ni, Pb, As, Zn and Sr metals in tap water supplied by Upper Silesia Water Plant to the inhabitants of the Upper Silesia region (Poland). It is the main supplier of drinking water to several million inhabitants of this agglomeration. Samples were taken and analyzed quarterly in 2019. The sampling points were chosen to help identify the source when an elevated level of a particular contaminant is observed. ICP-MS and ICP-OES have been used to measure the concentrations of those elements. The chronic daily intake (CDI), hazard quotient (HQ) and hazard index (HI) results for non-carcinogenic risk assessment of metals in tap water has been assessed. CDI values of non-carcinogenic metals were higher in children than in adults; the CDI values for adults and children were found in the order of: Zn > Sr > Cu > Mn > Ni > Pb > Cr > Co > As. All the studied metals had HQ values below 1, the risks caused by the non-carcinogenic metals decreased in the following order: Zn > Cu > Co > As > Sr > Pb > Cr > Ni > Mn. HI values were also less than 1, that meaning that the analyzed tap water is safe for human consumption. The concentration of As, Cr, Cu, Mn and Ni in analyzed tap water is in accordance with Polish and international requirements.

这项研究的重点是评估上西里西亚水厂向上西里西亚居民提供的自来水中某些Cr，Co，Mn，Cu，Ni，Pb，As，Zn和Sr金属的含量对人体健康的风险地区（波兰）。它是这一集聚区数百万居民的主要饮用水供应者。在2019年每季度进行一次采样和分析。当观察到特定污染物的水平升高时，选择采样点可帮助识别来源。ICP-MS和ICP-OES已用于测量那些元素的浓度。已评估了自来水中金属的非致癌风险评估的慢性每日摄入量（CDI），危险商（HQ）和危险指数（HI）结果。儿童中非致癌金属的CDI值高于成人；成人和儿童的CDI值按以下顺序找到：锌>锶>铜>锰>镍>铅>铬>钴>砷。所有研究的金属的HQ值均低于1，由非致癌金属引起的风险按以下顺序降低：Zn> Cu> Co> As> Sr> Pb> Cr> Ni> Mn。HI值也小于1，这意味着所分析的自来水可安全用于人类食用。分析的自来水中As，Cr，Cu，Mn和Ni的浓度符合波兰和国际要求。铬>镍>锰。HI值也小于1，这意味着所分析的自来水可安全用于人类食用。分析的自来水中As，Cr，Cu，Mn和Ni的浓度符合波兰和国际要求。铬>镍>锰。HI值也小于1，这意味着所分析的自来水可安全用于人类食用。分析的自来水中As，Cr，Cu，Mn和Ni的浓度符合波兰和国际要求。
