Assessment study on health safety of copper water tube

摘要

摘要:
目的评价不锈钢水管对我国水质的影响。
方法对采集的2家国内企业生产的不锈钢水管进行检测, 现场分析检测, 随机选择4家用户。
结果实验室检测中不合格指标有铅、铬、镍、砷; 而pH、余氯、总碱度、总硬度、溶解性总固体、硫酸盐、氯化物、硝酸盐、铜、锌、镉、锡均合格。现场检测中不合格指标有镍; pH、余氯、总碱度、总硬度、溶解性总固体、硫酸盐、氯化物、硝酸盐、铜、铅、锌、铬、镉、锡、砷均合格。
结论除了镍以外, 不锈钢水管其余指标均能达到我国饮用水水质卫生要求。

Abstract:
Objective To assess the effect of steel water tube on drinking water in China.
Methods In the labor atory study, to purchase steel water tube from two factories of China at market.In the applying field water quality study, torandomly select 4 users of steel water tube.
Results In the laboratory study, lead, chromium, nickel and arsenic are not all up to the standards.pH, residual chlorine, total alkalinity, total hardness, total dissolved solids, sulphate, chlor ide, nitrate, copper, zinc, cadmium and tin are all up to the standards.In the apply ing field water quality study, nickel are not all up to the standards.pH, residual chlorine, total alkalinity, total hardness, total dissolved solids, sulphate, chloride, nitrate, copper, lead, zinc, chromium, cadmium, tin and arsenic are all up to the standards.
Conclusion Excepting nickel, otheritems of steel water tube may meet the sanitary standards for drinking water in China.
