    摘要:

    目的:调查河北邯郸地区贫困农村饮用水毒理指标现状,分析其影响因素,为该地区水质监测、水质处理等工作提出建议和意见,为进一步推动贫困地区新农村建设提供新思路。方法:于2017-2020年在河北邯郸地区贫困农村采集饮用水水样6860份,根据《生活饮用水卫生标准》(GB 5749-2006)对毒理指标进行评价,Logistic回归模型分析河北邯郸地区贫困农村饮用水毒理指标的影响因素。结果:2017~2020年邯郸地区贫困农村饮用水毒理指标合格率相比,差异有统计学意义(P<0.05),并随年份递增,饮用水毒理指标合格率呈上升趋势,其中2017年最低,合格率为87.51%,2020年最高,合格率为96.81%;2017~2020年间,除四氯化碳、硒、氰化物外,其他毒理指标均具有不同程度超标现象,按照超标程度超标前四位依次为氟化物、硝酸盐氮、六价铬、铅;Logistic回归模型分析,结果显示,水质未处理、未按照要求使用消毒设备、不消毒、有污染源、小型供水规模是毒理指标不合格的危险因素(P<0.05)。结论:河北邯郸地区贫困农村饮用水水质得到较大改善,毒理指标合格率呈逐年上升趋势,国家的政策扶持为其提供了重要保障;但受多种因素影响,部分毒理指标仍存在超标现象,需相关部门切实抓好农村供水工程,加强邯郸市贫困农村饮水安全工程运行管理工作,做好农村水源保护,强化水厂管理,不断探索农村饮用水处理工艺,以推进农村供水发展,改善农村饮用水水质。

    Abstract:

    Objective To investigate the status quo of drinking water toxicology indicators in poor rural areas of Handan, Hebei, and analyze its influencing factors. To provide suggestions and opinions for water quality monitoring and water quality treatment in this area, and to provide new ideas for further promoting the construction of new rural areas in impoverished areas. Methods From 2017 to 2020, 6860 drinking water samples were collected from impoverished rural areas in Handan, Hebei. According to the "Sanitary Standards for Drinking Water" (GB 5749-2006), the toxicological indicators were evaluated. And the logistic regression model was used to analyze the influencing factors of drinking water toxicological indicators in the poor rural areas of Handan, Hebei. Results From 2017 to 2020, the difference in the qualified rate of drinking water toxicological indicators in the poor rural areas of Handan was statistically significant (P<0.05). And with the increase in years, the pass rate of drinking water toxicology indicators showed an upward trend. Among them, the pass rate was the lowest in 2017, with a pass rate of 87.51%, and the highest in 2020, with a pass rate of 96.81%. From 2017 to 2020, except for carbon tetrachloride, selenium, and cyanide, other toxicological indicators all exceeded the standard to varying degrees. According to the degree of exceeding standard, the top four were fluoride, nitrate nitrogen, hexavalent chromium and lead. Logistic regression model analysis showed that untreated water, not using disinfection equipment as required, non-disinfection, pollution sources, and small-scale water supply were the risk factors for unqualified toxicological indicators (P<0.05). Conclusion The quality of drinking water in poor rural areas in Handan, Hebei has been greatly improved, and the qualified rate of toxicological indicators has been increasing year by year, and the national policy support has provided an important guarantee for it; however, some toxicological indicators still exceed the standards due to various factors. It is necessary for relevant departments to do a good job in rural water supply projects, strengthen the operation and management of poor rural drinking water safety projects in Handan City, do a good job in rural water source protection, strengthen water plant management, and continuously explore rural drinking water treatment techniques to promote rural water supply development and improve rural drinking water quality.
