摘要
对全省饮水卫生状况进行了调查,设采样点1576个。在枯水期、丰水期两次采样做理化及细菌学分析。调查结果表明,96.47%人口饮用地下水,30.2%人口为集中式供水。水源卫生防护很差,55.46%的水源周围30米以内有厕所、猪圈等污染源,很多水井井口保护不好,造成水质污染。深井和浅井大肠菌数合格率仅分别为53.41%及29.73%。约有50%的人口饮用低碘水(<10微克/升)。大约500万人饮用高氟深井水(>1毫克/升)。这些是河北省饮水卫生中存在的主要问题。文中还报导了饮用深井、浅井及地面水的感观、化学及毒理学其它各指标的调查结果。
An investigation of water supply hygiene was conducted in Helei Province. 1576 water sources were sampled for analysis of physics, chemistry and microbiology. The result shows that 96.47% of population consume ground water and 30.2%enjoy tap water. Protection of water sources is poor. There are contamination sources, such as latrines and pigsties, within 30M of water sources. A number of well mouths fail to prevent from centami-nation. Qualified rates of coliform counts of deep-well water and shallow-well water are only 53.41 S and 29.73% respectively. About 50% of population drink water with low level of iodine ( <10μg/L ) . 5 million people have drinking water containing over 1mg/L F. These are the main problems of water supply in this province. This paper presents the results of other indexes of sense, chemistry and toxicology of ground water and surface water.
