目的了解地震灾区饮用水安全卫生状况。方法从2008-05/2009-02按生活饮用水标准检验方法对来自4个极重灾县的饮用水进行连续检测分析。结果共检测水样712份,433份合格,合格率60.81%。2008-05-15/06-13检测水样292份,合格率34.59%;2008-06-14/2009-02-13检测水样420份,合格率79.05%。总共测定31个项目,有21个不符合卫生标准,菌落总数、总大肠菌群、浑浊度、铁、锰和氨氮为主要不符合卫生标准的项目。结论4个极重灾县的饮用水在地震后受到较大影响,地震1个月后水样合格率逐步提高,保证了大灾之后不发生由饮用水引发的疫情。
Objective To understand the status of drinking water safety and sanitation in the earthquake stricken areas. Methods From May 2008 to February 2009, drinking water from four extremely severely affected counties was continuously tested and analyzed according to the standard test method for drinking water. Results A total of 712 water samples were tested and 433 were qualified with a pass rate of 60.81%. 292 samples were tested for water quality with a pass rate of 34.59%; 420 samples were tested for water samples with a pass rate of 79.05%. A total of 31 items were tested, 21 of which did not meet health standards, the total number of colonies, the total coliforms, turbidity, iron, manganese and ammonia nitrogen were the main items that did not meet sanitation standards. Conclusion Drinking water in the four most severely affected counties was greatly affected after the earthquake. The passing rate of water samples gradually increased after one month of earthquakes, ensuring that the epidemic caused by drinking water did not occur after the disaster.
