摘要
目的系统地掌握全省地方性氟中毒防治现状,为防治工作提供依据。方法采用分层整群抽样方法,在全省14个病区县的轻、中、重病区抽取有代表性的屯作为监测点;用氟离子电极法检测监测点居民水氟含量和8～12岁儿童尿氟;采用Dean氏法调查监测点8～12岁儿童氟斑牙患病率。结果改水监测点8～12岁儿童氟斑牙平均检出率达到病区控制标准。有13个改水监测点儿童尿氟达到≤1.5mg/L的控制标准。改水病区氟骨症患病率明显低于未改水病区(χ2=119.61,P<0.05)。结论改水病区8～12岁儿童的氟斑牙检出率、平均尿氟水平及成人氟骨症患病率均得到较好控制,未改水病区氟中毒病情仍较严重,需加大改水力度,控制氟源,预防地方性氟中毒的发生发展。
Objective To grasp the whole provinceses local fluorine poisoned prevention and cure work present condition of the system, and provide a basis for prevent and cure . Methods Adopt the whole flock of sampling method of layering, in the whole provinceses 14 disease area Counties of lightly, the medium, the heavy disease area take out sample village as surveillance site. Examine the rate of fluorine spot tooth of children aged 8 to 12 years at school was examined with Dean index. The fluorides content in urine of children aged 8 to 12 years was determined with FSLE method. Results Change the water diseas District village 8 to 12 years old children fluorine spot tooth rate achieve the disease control standard. The children＇s urine fluorine of 13 site have reached ≤ 1.5 mg/L the control standard . chang the water disease District fluorine bone disease rate fall lower obviously than no change water disease District （ X^2 = 119.61, P 〈 0. 05 ）. Conclusions Change the water disease District 8 to 12 years old child fluorine spot tooth rate, the average urine fluoride level and adult＇s fluorine bone disease rate get more control. No change a poisoned condition of the water disease District fluorine to still compare severlty, need enlargement to change the water power degree, control the fluorine source, prevent the occurrence that local fluorine be poisoned from develop.
