摘　　要：目的　对枣阳市改水降氟工程防治地氟病效果进行评价 ,科学地指导防制工作。方法　对监测点改水后的水氟、8～ 12岁儿童氟斑牙及尿氟进行监测。结果　改水后的水质好 ,水氟含量稳定。改水前后水氟含量下降 1.79mg/ L ,十几年来一直控制在国家标准 1.0 m g/ L以内 ,无较大波动。 8～ 12岁儿童尿氟几何均值由改水前6 .2 8mg/ L降至 0 .82 m g/ L ,氟斑牙患病率由改水前 85 .9%降至 1997年的 13.0 % ,氟斑牙指数由 1.74降到0 .2 9,流行强度由中等降至阴性 ,达到非病区标准。结论　改水降氟工程成效显著。病区人民只有通过改水降氟这一经济有效措施 。Objective To evaluate a project in which water source was altered to lower fluoride.Methods To moniter dental fluorosis and fluoride in urine.Results Fluoride in drinking water decreased 1.79mg/L after water source was changed.Fluoride in urine decreased considerably.Incidence of dental fluorosis decreased from 85.9% to 13.0%.Conclusions The project is very effective.
