|
摘要
目的评估"5.12"大地震后四川广元地区生活饮用水水质卫生质量状况。方法应用快速检测和常规实验室联用检测技术对灾后四川广元地区37个生活饮用水水质指标进行监测,并对其质量安全状况进行了综合分析。结果监测数据显示水样合格率为64.86%,不合格的最主要原因是菌落总数、总大肠菌群超标,但感官和化学指标未见异常。结论该地区生活饮用水水质在地震灾害后未发生显著的变化,亦未有致病菌的污染。
Objective To assess the quality and safety of drinking water in Guangyuan area of Sichuan province after "5.12" Wenchuan earthquake.Method 37 indexes of drinking water in Guangyuan area were monitored with rapid detection and conventional laboratory methods.The status of quality and safety were comprehensively analyzed.Results The qualified rate was 64.86%.The main unqualified reasons were that the colony count and total coliform group exceeded the standards,but there were no abnormal changes on sensory examination and chemical indexes.Conclusion The significant chemical and pathogens contamination of quality of drinking water were not found in Guangyuan area after "5.12" earthquake.
