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 health status of drinking water in rural areas of Yangtze River and Huaihe River in Jiangsu Province. Methods From January to October 2007, 53 county (city) rural drinking water centralized water supply units and decentralized water supply and sanitation were surveyed in accordance with the “2007 Rural Drinking Water Health Monitoring Program in Jiangsu Province” covering the Yangtze River and Huaihe River in Jiangsu Province. situation. Results Jiangsu Province, a comprehensive evaluation of drinking water pass rate of 41.34%. The indicators of low qualified rate of drinking water in rural areas covered by Yangtze River and Huaihe River were 49.64%, 79.69%, 85.75%, 88.78%, fluoride (92.63%), the remaining indicators pass rate above 95%. Compared with the Huaihe River system, the fluoride content in the Yangtze River water system was lower, and the total coliforms, turbidity and manganese content were higher, with significant differences (P <0.01). The contents of arsenic in Zhenjiang and Yancheng were higher than those in other areas, the differences were statistically significant (P <0.01). Conclusion The water quality of rural drinking water in the Yangtze River and Huaihe River areas in Jiangsu Province needs to be improved urgently.
