目的掌握勐腊县农村饮用水的水质卫生状况,为制订农村饮用水安全决策提供科学依据。方法采用分层随机的方式,抽取部分农村安全饮水工程监测点采集水样,对农村饮用水的氟、砷含量开展监测。结果 2 552份水样的水氟、水砷含量均未超标。其中水氟含量<0.2mg/L的水样占38.2%,0.2～0.96mg/L之间的水样占61.8%;水砷含量<0.01mg/L的水样占96.1%,0.01～0.04mg/L之间的水样占3.9%。结论勐腊县农村饮用水氟、砷含量经检测均在标准范围,表明勐腊县水质未受砷、氟污染。
Objective To understand the sanitary status of drinking water in rural Mengla County and provide a scientific basis for making drinking water safety decisions in rural areas. Methods A stratified random approach was adopted to collect water samples from some rural safety drinking water project monitoring points to monitor fluoride and arsenic contents in rural drinking water. Results 2 552 samples of water fluoride, water arsenic content were not exceeded. The water samples with water fluorine content <0.2mg / L accounted for 38.2%, the water samples with 0.2 ~ 0.96mg / L accounted for 61.8%, the water samples with water arsenic content <0.01mg / L accounted for 96.1%, 0.01 ~ 0.04mg / L of water samples accounted for 3.9%. Conclusion The detection of fluorine and arsenic in rural drinking water in Mengla County are in the standard range, indicating that the water quality of Mengla County is not contaminated by arsenic and fluorine.
