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。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,毒理指标进行评价,logistic回归模型分析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),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,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,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,改善农村饮用水水质。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^(2)017 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^(2)017 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^(2)017 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 fo
