上海市闵行区城市饮用水水质和水性疾病调查研究

目的了解城市饮用水水质与水性疾病发病及相关死因情况。方法选择上海闵行区有一定代表性水厂的出厂水、末梢水、二次供水等51个水质监测点进行监测;在水质监测地区分别收集二级综合性医院、幼儿园、小学各2家中发生的与水相关的急慢性消化道病例和死因等信息;分析水质情况与水性疾病发生的流行病学特征。结果各类型水质总合格率超过91%,不合格项目主要为耗氧量和氨氮,丰水期水质合格率高于枯水期;水性疾病以细菌性痢疾、其他感染性腹泻、各型肝炎为主,占监测病例的94.01%。发病总体呈现夏秋季发病率上升、冬春季下降的流行病学特征;肿瘤及慢性非传染性疾病死因1020例。医院传染病门诊共监测到各型菌痢5例,肝炎72例;幼儿园、小学中有502人次出现过消化道症状和因病缺课,但未监测到急性水性疾病的发生。结论该区水源水有机物污染比较严重,应加强城市供水水源水的保护。另外,该调查提示水性疾病的发生有一定的流行病学特征。
