【摘要】 目的了解地震对四川某重灾区饮水卫生状况的影响,指导受灾群众及抗震救灾部队的饮水卫生。方法调查某重灾区所有水源,采取连续与间隔检测的方法对灾区12个水源41份水样进行检测。结果地震对部分水源的饮水设施产生了破坏,不同检测指标合格率有较大差异。结论毒理学指标中铅、汞等均不超标,表明震后水源并未受到重金属等毒物的污染。而饮水浑浊度和肉眼可见物等指标不符合标准会产生不良后果,教育受灾群众及抗震救灾部队养成良好的饮水卫生习惯及环境卫生治理对提高饮水安全性有重要作用。灾后余震频发,及时修补破损的输水管道对于保证饮水卫生具有重要意义。更多还原

【Abstract】 Objective To understand the influence of earthquake on hygiene state of drinking water in a serious disaster area,and to direct local residents and earthquake relief forces with correct drinking water knowledge.Methods All water resources in this disaster area were investigated.Continuous and interval detection was used to determine 41 water samples came from 12 water resources.Results Some drainage facilities were damaged by earthquake.The qualified rates of the different parameters showed significant differences.Conclusions Some of toxicological parameters such as lead,mercury,etc.met criteria,which indicated there was no heavy metal pollution in water resources.Discrepancy of parameters about turbidity,visible residue by naked eyes may bring about some bad consequences.The effect of directing local residents and earthquake relief forces with correct drinking water knowledge and putting environment sanitation in order is prominent.Aftershock is frequently,it is important to restore damaged drainage facilities of drinking water in time.更多还原
