【摘要】 目的掌握河北省居民饮水砷状况以及是否存在地方性砷中毒。方法在重点地区采取随机抽样方法选择调查点进行饮水砷测定及地方性砷中毒调查。结果全省5个县25个乡125个村共采集测定水样528份,水砷在0～0.048 mg/L之间,全部在正常标准以内。位于河北省北部山区和半山区的阳原和围场县的水砷较高,水砷均值都在0.01 mg/L以上。位于河北省中、南部平原的三河、博野和隆尧县的水砷较低,水砷均值都在0.01 mg/L以下。在125个村的走访调查中,未发现砷中毒病人。结论河北省居民饮水砷处于较低水平,未发现地方性砷中毒流行。更多还原

【Abstract】 Objective To survey the arsenic content of inhabitants’ drinking water and endemic arsenic poisoning in Hebei province.Methods The investigated sites were randomly sampled in possible regions where determination of arsenic content in drinking water and survey on endemic arsenic poisoning was carried out.Results Arsenic content was between0～0.048mg/L and was totally below the normal standard in the528water samples collected in125villages of25towns belong to5counties.The arsenic content in Yangyuan and Weichang counties located in mountain areas in northern part was relatively higher,with the mean of arsenic content in drinking water being over0.01mg/L.The arsenic content in Sanhe,Longyao and Boye counties located in plain areas in southern part was relatively lower,with the mean of arsenic content in drinking water being below0.01mg/L.No patient suffering from endemic arsenic poisoning was found during the survey in125villages.Conclusions The arsenic content in inhabitants’ drinking water in Hebei province is at low level.It is not found that endemic arsenic poisoning prevailed in Hebei province.更多还原
