饮用地下水是农村居民饮水中的重要组成部分,关系着农村居民的身体健康.我国部分地区均存在着饮用地下水的安全问题.为了解湖北省武汉市农村地下饮用水的卫生学状况,于2007年8月～11月对武汉市新洲、黄陂、蔡甸、江夏、洪山5个远城区的农村地下饮用水进行调查.

Objective To know the cause for contamination of drinking water in a hotel. Methods Samples were taken from the reservoir 1 h, 14 h, 22 h and 33 h after contamination and the perceptible character, chemical and bacteriological test were done by using the methods in Analytical Methods for Water and Sanitary Standard for Drinking Water Quality(2001). Results The turbidity increased at 14 h after contamination and the highest level reached 3.82 NTU. The residual chlorine in tap water from the reservoir was less than 0.05 mg/L, the total count of bacteria was 940 cfu/ml, the total coliform bacteria was more than 1 600 MPN/100 ml and fecal coliforms was 130 MPN/100 ml. Conclusion The contamination of drinking water in the investigated hotel is caused by drinking water reservoir leakage, so more attention must be paid to the contamination of drinking water reservoir.

游泳场所已成为人们娱乐消暑纳凉、休闲和健身的主要场所之一,因此游泳池水质量直接关系到游泳者的身体健康.本文分析了我市游泳池存在的卫生问题,为提高游泳池水质量和提高卫生管理工作提供管理思路.

本文通过1998年2月-2000年12月对武汉地区2个城郊农村经沼气发酵处理及未经任何处理的粪便分别用作蔬菜种植肥料、鱼塘养鱼饲料的使用情况进行了卫生学调查.粪便经沼气发酵处理后粪便大肠菌群值、活蛔虫卵、寄生虫对菜地土壤、蔬菜、鱼塘水质、鱼产品污染均有明显降低,粪大肠菌值自10-8-10-7降至10-3-10-2,蛔虫卵死亡率达90%,经STATISTICA软件包处理,差别有极显著性意义(P＜0.05);建有沼气池的厕所苍蝇密度较未建沼气池厕所为低.通过此次调查结果证实,沼气发酵是一种既能利用肥源、能源,又有利除害灭病和改善环境卫生的粪便无害化处理方法之一.
