摘要
目的通过对2016—2018年呼和浩特市生活饮用水类金属砷的监测,分析呼和浩特市生活饮用水类金属砷含量情况,为相关部门提高饮用水水质提供科学依据。方法根据内蒙古自治区疾病预防控制中心制定的农村和城区饮用水水质卫生监测技术方案,结合2016—2018年农村和城区自来水供应的实际情况,按照《生活饮用水标准检验方法水样的采集与保存》(GB/T 5750.2—2006)采集3年间的农村和城区自来水水样开展检测。结果2016—2018年呼和浩特市5个旗县和4个区的城区饮用水砷含量均达到《生活饮用水卫生标准》(GB 5749—2006)的标准;但托克托县城市枯水期饮用水砷含量高于其他城市,差异有统计学意义(χ^(2)=24.18,P<0.05),2016、2018年武川县农村枯水期(0.0035 mg/L)饮用水砷含量高于丰水期(0.0012 mg/L),差异有统计学意义(χ^(2)=11.49,P<0.05)。结论2016—2018年呼和浩特市生活饮用水金属砷含量农村普遍高于城区,丰水期高于枯水期。
Objective To analyze the arsenic content by monitoring arsenic of drinking water in Hohhot from 2016 to 2018,and to provide scientific basis for competent authorities to improve drinking water quality in Hohhot.Methods According to the technical plan for rural and urban drinking water sanitation monitoring formulated by the Inner Mongolia Autonomous Region Center for Disease Control and Prevention,the tap water samples from rural and urban areas during 3 years for testing were collected in accordance with The Standard Examination Methods for Drinking Water-Collection and Preservation of Water Samples(GB/T 5750.2—2006)in combination with actual situation of tap water supply in rural and urban areas from 2016 to 2018.Results The arsenic content of drinking water in the urban areas of 5 banner-based counties and 4 districts of Hohhot satisfied Standards for Drinking Water Quality(GB 5749—2006)from 2016 to 2018;while the arsenic content of drinking water in Tuoketuo County was higher than that in other cities,and the difference was statistically significant(χ^(2)=24.18,P<0.05).The arsenic content of drinking water during dry seasons(0.0035 mg/L)was higher than that during wet seasons(0.0012 mg/L)in rural Wuchuan County in 2016 and 2018,and the difference was statistically significant(χ^(2)=11.49,P<0.05).Conclusion The arsenic content of drinking water in rural areas is higher than that in urban areas in Hohhot from 2016 to 2018,which during wet seasons is higher than that during dry seasons.
