目的通过检测石家庄市饮用水中铝的含量分析铝对人体的危害。方法对2011年检测的水样进行铝元素分析,水样包括各单位送检的水样282份,其中178份二次水、104份井水;按全市均匀布点采样,二次水26份、井水23份、出厂水6份。结果各单位送检的二次水铝的检出率是52.8%,其中铝含量<0.01mg/L的84份,>0.11mg/L的8份;井水中铝的检出率是25.0%,其中铝含量<0.01mg/L的78份,>0.11mg/L的1份。按全市均匀布点采样,二次水铝的检出率是61.5%,铝含量<0.01mg/L的10份,>0.11mg/L的1份;井水中铝的检出率是56.5%,铝含量<0.01mg/L的10份,>0.11mg/L的1份;出厂水中铝检出率100.0%,铝含量>0.11mg/L的2份。结论铝含量高于0.11mg/L,对人体有潜在的危害,供水部门及相关部门应引起重视。
Objective To analyze the hazard of aluminum on human body by detecting the content of aluminum in drinking water in Shijiazhuang. Methods Aluminum analysis was performed on the water samples tested in 2011. The water sample included 282 water samples sent by each unit, of which 178 were secondary water and 104 well water samples. According to the city’s uniform sampling and sampling, 26 secondary water, Well water 23, factory water 6 copies. Results The detection rate of secondary hydrated aluminum in each unit was 52.8%, of which 84 were aluminum content <0.01mg / L and 8 were> 0.11mg / L. The detection rate of aluminum in well water was 25.0% , Of which 78 parts aluminum content <0.01mg / L, 1 part> 0.11mg / L. According to the city uniform sampling, the detection rate of secondary aluminum is 61.5%, aluminum content of <0.01mg / L of 10,> 0.11mg / L of 1; well water detection rate of aluminum is 56.5% 10 parts of aluminum content <0.01mg / L, 1 part of> 0.11mg / L; 2 parts of aluminum in the factory water with the detection rate of 100.0% and aluminum content> 0.11mg / L. Conclusion Aluminum content is higher than 0.11mg / L, which has potential harm to the human body. Water supply department and relevant departments should pay attention to it.
