摘要
目的分析比较柳州市3种生活饮用水的水质,为选择健康饮水提供参考。方法按照国家卫生标准GB/T 5750-2006对自来水、纯净水、井水进行包括感官性状、一般化学、毒理学、微量元素在内的多项指标的水质分析,并参照国家卫生标准(GB 5749-2006)进行分析比较。结果自来水、纯净水各项指标均符合相应的国家卫生标准。井水除色度,pH值,铜、汞、锌含量外,其他指标均未达到生活饮用水卫生卫生标准。结论纯净水所有微量元素含量明显低于自来水和井水,长期饮用后的健康效应值得深入研究。
[Objective] To analyze and compare quality of the 3 kinds of drinking water, and provide reference evidence for Healthy drinking. [ Methods] A number of indicators of water quality, including sense character, general chemistry, toxicology, microelements of the water samples from tap water, purified water and well water were analyzed by national health standard （ GB/T 5750 -2006）, and compared by national health standard （GB 5749 -2006）. [Results] Indicators of tap water and purified water met the related national health standards, while that ofwell water, except for the level of chroma, pH, copper, mercury, zinc, did not meet the healthy standards of drinking water. [ Conclusion] Microelements levels of purified water are significantly lower than that of tap water and well water, the long-term health effects after drinking are worthy of in-depth study.
