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 understand the characteristics of toxicological indicators of water supplied by a certain department and provide a basis for scientific water improvement. Methods The collection, storage, transportation and testing of water samples are conducted in strict accordance with the “Standard Test Method for Domestic Drinking Water” (GB / T5750-2006). Evaluation criteria based on “drinking water health standards” (GB / T5749-2006). Results Among 195 water sources, 21 fluoride exceeded water sources, 9 lead exceeded water sources and 2 cadmium exceeded water sources, accounting for 10.8%, 4.6% and 1.0% of the investigated water sources respectively. Conclusion Most of the toxic water sources in a certain department have reached the drinking water standards stipulated by the state, but some water sources still have excessive toxicological indicators. Water diversion measures should be taken according to different reasons.
