目的 观察安达监测点的防治措施效果及其病情状况。方法 采用流行病学设计方法 ,水氟含量和儿童尿氟含量用氟离子选择电极法检测 ,儿童氟斑牙采用 Dean氏法进行检查。结果 在爱国村 ,羊草 1,2队 ,羊草 3,4队三个监测点中 ,水氟含量分别为 :3.31、7.89、1.6 3mg/L;儿童尿氟含量分别为 :3.2 9、8.93、2 .88mg/L;儿童氟斑牙患病率分别为 :70 .90 % ,94.44 % ,5 9.6 5 %。结论 监测点水氟含量出现回升 ,其中羊草 1,2队水井氟含量回升水平最高 ,病情最重。应立即采取措施 ,降低饮用水氟含量 ,以控制病情
Objective To observe the effect of prevention and treatment measures and the condition of Andhra surveillance sites. Methods The epidemiological design method was used. The fluorine content in water and urinary fluoride in children were detected by fluoride ion selective electrode method. The children’s dental fluorosis was examined by Dean’s method. Results In the three monitoring sites of Aiguo Village, Leymus chinensis 1 and 2, and Leymus chinensis 3 and 4, the fluoride levels in water were 3.31, 7.89 and 1.63 mg / L, respectively. The urinary fluoride levels in children were 3.2 9 and 8.93 , 2.88mg / L; children dental fluorosis prevalence rates were: 70.90%, 94.44%, 59.6%. Conclusion The fluorine content of water in the monitoring spot rebounded, in which the fluoride content of wells in the two wells of Leymus chinensis had the highest level of recovery and the most serious disease. Immediate measures should be taken to reduce the fluoride content of drinking water to control the disease
