摘　　要：目的了解江苏省境内长江、淮河两水系农村饮用水卫生现况。方法于2007年1—10月,按照《2007年江苏省农村饮用水卫生监测方案》调查江苏省境内长江、淮河两水系覆盖的53个县(市)农村饮用水集中供水单位和分散式供水卫生现况。结果江苏省农村饮用水综合评价合格率为41.34%。长江、淮河两水系覆盖的农村饮用水单项指标合格率较低的指标有余氯(49.64%)、总大肠菌群(79.69%)、浑浊度(85.75%)、细菌总数(88.78%)、氟化物(92.63%),其余指标合格率均在95%以上。与淮河水系相比,长江水系氟化物含量较低,总大肠菌群、浑浊度、锰含量较高,差异均有统计学意义(P<0.01)。镇江、盐城两市水砷含量高于其他地区,差异均有统计学意义(P<0.01)。结论江苏省境内长江、淮河水系范围农村饮用水水质亟待改善。Objective To understand the hygienic situation of drinking water in the rural areas in the river system of the Yangtze and Huaihe in Jiangsu Province,and to provide the scientific evidence for improving the quality of drinking water. Methods From January to October in 2007, according to the guideline of drinking water quality monitoring in the rural areas,in the river system of the Yangtze and Huaihe in Jiangsu Province,in 53 counties （cities）,the drinking water quality of the central water supply and the non-central water supply was investigated. Results From the result of comprehensive evaluation, the eligible rate of drinking water in the rural areas in the river system of the Yangtze and Huaihe in Jiangsu Province was 41.34%. As for residual chlorine the eligible rate was 49.64%, as for total coliform group it was 79.69%, as for total number of bacteria it was 88.78% ,as for the turbidity it was 85.75%, as for fluoride it was 92.63% ,as for the other indexes it was above 95%. Compared with the Huaihe river system, the fluoride content in the Yangtze river system was lower,total coliform group, turbidity and manganese content were higher （P〈0.01）.In Zhenjiang and Yancheng, arsenic content in water was higher than that in the other areas （P〈0.01）. Conclusion The drinking water quality in the rural areas in the river system of the Yangtze and Huaihe in Jiangsu Province is considered at the low level and the improvement should be done as soon as possible.
