大同市自来水矿质元素分析

Analysis of the Mineral Elements of Drinking Water in Datong

自来水的卫生标准状况直接关系到全体市民的身体健康。通过对大同市市区、矿区和大同大学校区的自来水中矿质元素的含量分析,发现大同市自来水均富含人体所必需的矿质元素,基本符合市民的用水质量要求,但Al,As和Hg元素的超标会直接影响市民的身体健康。建议相关部门对水源进行改善治理以及提高自来水净化处理技术水平,以保障市民的健康用水。

The health standard conditions of drinking water quality are directly related to the health of all people.Drinking water samples from three regions in Datong were sampled,of which the mineral elements were detected and comparatively analysed.The results showed that there were rich in the essential mineral elements in drinking water from Datong,such as Fe,Mn,Cu,Zn,Na,K,Ca,Mg,Si,B,etc.which met people＇s basic water quality requirements.However,three hazardous elements（Al,As,Hg） were also existent in drinking water,and they all exceeded the limits of sanitary standard for drinking water,which directly affected the health of people.In order to safeguard health standard of drinking water,it is suggested that the relevant departments should improve the governance of water resources and increase the level of water purification technology.
