【摘要】 目的了解阿坝州饮用水水质卫生状况及变化趋势,为政府制定卫生政策提供科学依据。方法分别于枯水期和丰水期对阿坝州城区和农村生活饮用水水质监测点进行采样监测,按(GB 5749-2006)、(GB/T 5750-2006)进行检测与评价。结果 2015-2017年共监测水样2 946份,总合格率为47.73%;城区出厂水与末梢水合格率分别44.83%48.57%(P>0.05);农村饮水安全工程、小型集中式供水和分散式供水合格率分别为40.59%、54.42%、53.23%(P<0.05);枯水期与丰水期合格率分别为51.99%,43.40%(P<0.05)。微生物指标、感官性状和一般化学指标、毒理学指标合格率分别为54.51%、80.82%和99.02%。结论阿坝州生活饮用水水质监测总体合格率低,微生物指标不合格是阿坝州生活饮用水存在的主要卫生问题。更多还原

【Abstract】 Objective To understand the sanitary status and change trend of drinking water quality in Aba Prefecture, and thus to providing scientific basis for the Government to formulate health policies. Methods Sampling and monitoring of drinking water quality monitoring points in urban and rural areas of Aba prefecture were carried out in dry water period and Fung Water respectively, and were tested and evaluated according to(GB 5749-2006) and (GB/T5750-2006). Results A total of 2,946 water samples were monitored from 2015 to 2017 the total qualified rate was 47.73%. The city proper of factory water and peripheral water in urban areas were 44.83% and 48.57%, respectively(P >0.05). The qualified rate of rural drinking water safety project, small centralized water supply and dispersed water supply were 40.59%, 54.42% and 53.23%,respectively(P<0.05). The qualified rate of dry water period and Fung water period were 51.99% and 43.4%, respectively(P<0.05). The qualified rates of microbial indexes, sensory traits and general chemical indexes and toxicological indexes were54.51%, 80.82% and 99.02%, respectively. Conclusion The qualified rate of drinking water quality monitoring in Aba Prefecture is relatively low, and microbial over-standard is the main reason.更多还原
