摘要

目的:了解壬基酚(NP)在遵义市城区(红花岗区和汇川区)自来水中的含量,为防治NP污染提供数据支持。方法:?采样点:于2016年7月16日,根据水质检测采样点的设置要求,对红花岗区和汇川区的水源取水口、出厂水口和居民经常用水点处进行水样采集。?样本量:每个采样点重复采样三次,共采集样品30份。?样品处理:采用高效液相色谱仪进行。结果:红花岗区和汇川区的自来水均检测出NP,检出率达100%。水源水NP浓度范围为0.195~1.174μg/L,出厂水NP浓度范围为0.269~1.042μg/L,末梢水NP浓度范围为0.32~5.434μg/L。红花岗区与汇川区水源水中NP浓度分别为0.336±0.0237μg/L和0.805±0.332μg/L,差异无统计学意义(t=2.191,P>0.05);出厂水中NP的浓度分别为0.348±0.141μg/L和0.659±0.387μg/L,差异无统计学意义(t=1.443,P>0.05);末梢水中NP浓度分别为0.438±0.0746,2.774±1.66μg/L,汇川区是红花岗区的6倍(t=-4.348,P<0.05)。结论:本调查结果显示遵义市两城区自来水中均检出NP,水源水NP平均浓度与全国其他地区相比处于中等水平。汇川区末稍水平均浓度高于红花岗区,低于美国淡水水质基准标准6.6μg/L,高于我国生活饮用水酚类卫生标准0.002mg/L,有待进一步治理。
Objective: By surveying the nonylphenol(NP) content of tap water in Zunyi(Honghuagang district and Huichuan district) to provide data support for the prevention and control of NP pollution. Methods: ? Sampling point:Collecting the water intake, the water outlet of waterworks and the water points of residents often use in Honghuagang district and Huichuan district, according to the requirements of the water quality test on November 9, 2015.? Sample size: Setting the 5 sampling points each area and each point collected three times, 30 samples were collected in all.?Samples handing:By high performance liquid chromatograph. Results: NP ware detected in tap water of Honghuagang district and Huichuan district, the rate of detection was 100%, and the concentration range of source water is 0.195 ~ 1.174μg/L, the water outlet of waterworks is 0.269~1.042μg/L, tip water is 0.32~5.434μg/L.The concentration range of source water of Honghuagang district and Huichuan district are 0.336±0.0237μg/L,0.805±0.332μg/L respectively, no difference(t=2.191,P>0.05); The concentration range of the water outlet of waterworks of Honghuagang district and Huichuan district are 0.348±0.141μg/L, 0.659±0.387μg/L respectively, no difference(t=1.443,P>0.05); The concentration range of tip water of Honghuagang district and Huichuan district are 0.438±0.0746, 2.774±1.66μg/L respectively, Huichuan district is six times than Honghuagang district, difference(t=-4.348,P<0.05). Conclusion: The survey results show that both the city of Zunyi City tap water were detected in NP, NP averageconcentration of sources water at a moderate level compared to the rest of China.The NP average concentration of tip water in Huichuan was higher than Honghuagang, lower than the US fresh water reference standard 6.6μg/L and higher than Chinese drinking water phenolic health standards 0.002mg/L.Need to be further management.
