目的了解青河县饮茶型地方性氟中毒的病情危害程度,为制定防治措施提供科学依据。方法严格按照《新疆自治区饮茶型氟中毒流行病学调查方案》实施。结果儿童氟斑牙患病率为33%,成人氟斑牙患病率为10.5%;儿童尿氟均值为1.58mg/L,超标尿氟占68.25%,成人尿氟均值为2.78mg/L,超标尿氟占78.00%;成人氟骨症检出率为33.25%;检测饮用砖茶183份,测得茶水氟含量平均值3.85mg/L,其中茶氟含量最高值33.29mg/L,茶水氟含量超标样占93.44%。结论青河县居民饮用砖茶氟含量超标,是当地居民氟中毒危害的主要原因,且其中有6个乡(镇)的12个村是饮茶型和饮水型氟中毒叠加病区。
Objective To understand the extent of endemic fluorosis in drinking tea in Qinghe County and provide a scientific basis for making prevention and control measures. Methods in strict accordance with the Xinjiang Autonomous Region drinking tea fluorosis epidemiological survey program. Results The prevalence of dental fluorosis in children was 33%, and the prevalence of dental fluorosis in children was 10.5%. The average urinary fluoride in children was 1.58mg / L, the excessive urinary fluorine accounted for 68.25%, the average urinary fluorine in adults was 2.78mg / L, Excessive urinary fluoride accounted for 78.00%; adult skeletal fluorosis detection rate was 33.25%; drinking brick 183 tea, measuring the average fluorine content of tea 3.85mg / L, of which the highest content of tea fluoride 33.29mg / L, tea fluoride content Exceeded the sample accounted for 93.44%. Conclusion The fluoride content of brick tea in Qinghe County exceeded the standard, which is the main reason of fluorosis poisoning for local residents. Among them, 12 villages in 6 towns (towns) are the tea drinking-type and drinking-type fluorosis superimposed ward.
