某部自备水源水毒理学指标调查

Investigation on toxicology index of self-sustaining water supply in a PLA unit

目的了解某部自备水源水毒理学指标特征,为科学改水提供依据。方法水样的采集、保存、运输和检测严格按照《生活饮用水标准检验方法》(GB/T5750-2006)进行。评价标准依据《生活饮用水卫生标准》(GB/T5749-2006)。结果 195个水源中,氟化物超标水源21个、铅含量超标水源9个、镉含量超标水源2个,分别占调查水源数的10.8%、4.6%、1.0%。结论某部大部分自备水源水毒理学指标达到了国家规定的饮用水标准,但少数水源仍存在毒理学指标超标现象,应根据不同原因采取相应改水措施。

Objective To know the quality of self - sustaining water supply in unit of a PLA unit, and to provide scientific basis for improving water quality. Methods Samples were collected preserved, carried to and examined according to 〈 Standard test methods of drinking water 〉 （ GB/T5750 - 2006） , evaluation standard according to 〈 Drinking water health standards 〉 （ GB/T5749 - 2006 ） . Results Among the 195 water samples, there were 21 exceed fluoride water source, 9 exceed lead paint water sources and 2 exceed cadmium water source were accounted for 10. 8% , 4.6% and 1.0% respectively, all were above the standard limits. Conclusions Except for a few, the toxicology index of most detecting samples compliance with drinking water standards prescribed by the state, Countermeasures to improvement and management of water quality should be taken.
