贵阳市黔灵山泉水中26种元素的分析和评价

为考察饮用贵阳市黔灵山泉水是否对人体有益,使用ICP-MS(电感耦合等离子体质谱)对泉水中锂、铍、硼、铝、钛、钒、铬、锰、铁、钴、镍、铜、锌、镓、砷、硒、锶、钼、银、镉、锑、铯、钡、铊、铅和铀26种元素的含量进行了分析,并取自来水和市售瓶装水进行对比。结果表明:黔灵山泉水中元素含量符合国家对饮用水的要求,但其所提供的人体所需微量元素的含量与自来水和瓶装水相比并无明显优势。由于泉水不属于常规水源未对其进行日常监管,如果将黔灵山泉水作为饮用水源无明显益处,并存在一定风险。

Analysis and Evaluation of 26 Elements in Qianling Mountain Spring in Guiyang

To investigate the beneficial effects of drinking Qianling Mountain spring water in Guiyang,ICP-MS （Inductively Coupled Plasma Mass Spectrometry） is used to analyze the content of 26 elements in the spring water including Li,Be,B,Al,Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn,Ga,As,Se,Sr,Mo,Ag,Cd,Sb,Cs,Ba,T1,Pb and U.Meanwhile,tap water and commercially bottled water is also selected for comparison.The results show that the element content in such spring water complies with the national standards for drinking water.However,the trace elements contained in the spring water needed by human body are not obviously more advantageous,if compared with those in the tap water and bottled water.Since spring does not belong to routine water source,consequently it is not under regular supervision management.Therefore,there may be no obvious benefits and may even exist a certain risk if Qianling Mountain spring is used as drinking water.
