摘要
山泉水作为生活饮用水资源的重要组成部分,其水质状况直接关系到居民的身体健康和生命安全。为了全面了解全市山泉水水质污染状况,珠海市水质监测中心对全市23个代表性的山泉水取水点的氯化物、硝酸盐、硫酸盐以及氟化物四种无机阴离子指标进行了全面的调查和评估。结果表明:23份山泉水水样中,除1个山泉水水样的氟化物浓度超过1.0 mg/L标准限值外,其它水样四种阴离子浓度均低于生活饮用水卫生标准。同时,43.4%的山泉水水样在地表水Ⅳ或者Ⅳ类水质以下水平,表明我市山泉水水源已经受到一定程度的污染。山泉水的监管需要引起市政、水务以及卫生疾控等管理部门的重视,政府部门需做好监测、应急、宣传以及教育等工作,防控生活饮用水水源的安全性风险。
Mountain spring water is an important part of drinking water resources,and its water quality is directly related to residents'physical health and life safety.In order to fully understand the water pollution status of the mountain spring water in the city,Zhuhai Water Quality Monitoring Center conducted a comprehensive investigation and evaluation of the four inorganic anion indexes of chloride,nitrate,sulfate and fluoride in 23 representative mountain spring water intakes in the city.The results showed that the concentration of the four anions in water samples was lower than the sanitary standard of drinking water among the 23 spring water samples,except for one mountain spring water sample which the fluoride concentration exceeded the standard limit of 1.0 mg/L.At the same time,43.4%of mountain spring water samples were below the surface water levelⅣorⅣ,indicating that the source of mountain spring water in our city has been polluted to a certain extent.The supervision of mountain spring water needs the attention of municipal administration,water affairs and health and disease management departments.Government departments need to do a good job of monitoring,emergency response,publicity and education to prevent and control the safety risks of drinking water sources.
