目的：通过对重庆市綦江区2012年-2015年生活饮用水中氟化物、氯化物、硝酸盐氮、硫酸盐四种常见物质的监测结果进行分析，了解本地区的四种物质的含量及其分布情况，为本地区生活饮用水水质的提高提供科学依据。方法采用中华人民共和国国家标准GB/T 5750.5-2006中离子色谱法测定四种物质。结果共监测生活饮用水样924份，四种物质均值分别为：0.19mg/L、9mg/L、1.3mg/L、63mg/L。氟化物和氯化物在不同年份（F=2.548，P=0.055；F=2.615，P=0.051）、丰水期和枯水期的含量（t=0.479，P=0.632；t=-1.098，P=0.272）没有统计学差异；而硝酸盐氮含量两两比较发现2015年含量和2012年、2013年及2014年有统计学差异（t=4.234， P=0.005；t=5.127，P=0.000；t=5.023，P=0.000）；硫酸盐含量两两比较发现2013年和2014年有统计学差异（t=3.783，P=0.021），2015年和2012年及2013年有统计学差异（t=4.165，P=0.004；t=4.235，P=0.000）,而硝酸盐氮和硫酸盐含量在丰水期约高于枯水期(Z=-3.349，P=0.001；Z=-5.358，P=0.000)。结论重庆市綦江区2012年-2015年生活饮用水中氟化物、氯化物、硝酸盐氮、硫酸盐四种物质合格率都很高，说明水质质量控制得很不错。但仍有少量不合格存在，需进一步加强水质前处理和监测。

Objective To analyze the monitoring results of the four common materials of fluoride, chloride, nitrate nitrogen, sulfate in drinking water in Qijiang District Chongqing from 2012 to 2015, so as to understand the status of the content of four kinds of material and its distribution in the region, which will provide a scientific basis for the improvement of drinking water quality. Method According to the national standard of the People's Republic of China, Use the national standard GB/T 5750.5-2006 by ion chromatography. Results Monitoring of the drinking water samples of 924 ,the mean of the four common materials of fluoride, chloride, nitrate nitrogen, sulfate in drinking water are 0.19mg/L,09mg/L,1.3mg/L,63mg/L. the content of fluoride and chloride in different years(F=2.548,P=0.055;F=2.615,P=0.051), the plentiful water season and the dry season(t=0.479,P=0.632;t=-1.098,P=0.272) has no statistical difference; we find out that the content of nitrate nitrogen in 2015 and 2012, 2013 ,2014 is statistically difference (t=4.234,P=0.005;t=5.127,P=0.000;t=5.023,P=0.000) by comparing one to another in different years ; and we find out that the content of sulfate in 2013 and 2014(t=3.783,P=0.021), 2015 and 2012,2013(t=4.165,P=0.004;t=4.235,P=0.000)is statistically difference by comparing one to another in different years, And the content of nitrate nitrogen and sulfate in the plentiful season are above about the dry season (Z=-3.349,P=0.001;Z=-5.358,P=0.000).Conclusion Qualified rates of fluoride, chloride, nitrate nitrogen, sulfate in drinking water in Qijiang District Chongqing from 2012 to 2015 are very high, the results show that the drinking water is well commanded. But there still are a few unqualified, the pretreatment and monitoring of the drinking water need to be strengthened.
