目的了解理县饮茶型氟中毒病情范围与流行状况。方法采集饮用水样、(砖)茶水样和尿样用氟离子选择电极法检测氟含量,氟斑牙诊断采用Dean氏诊断标准,氟骨症诊断按照地方性氟骨症临床诊断标准。结果饮用水样氟含量均符合国家饮用水卫生标准(1.0 mg/L);400份(砖)茶水氟含量均值为1.59 mg/L。400名8～12岁儿童氟斑牙检出率29.25%,尿氟算术均数为0.43 mg/L;400名16岁以上成人氟斑牙检出率46.25%,临床氟骨症检出率32.25%;400份成人尿氟算术均数为0.73 mg/L。结论理县为饮茶型氟中毒轻病区,加强病情监测和健康教育是防治饮茶型氟中毒的关键。
Objective To understand the range and prevalence of drinking fluorosis in Li County. Methods Drinking water samples, water samples of tea (brick) and urine samples were tested for fluorine content by fluoride ion selective electrode method. The diagnostic criteria of dental fluorosis was Dean’s diagnostic criteria. The diagnosis of skeletal fluorosis was based on the clinical diagnostic criteria of endemic fluorosis. Results The fluoride content of drinking water samples were both in accordance with the national standard of drinking water (1.0 mg / L). The mean fluoride content of 400 tea samples (brick) was 1.59 mg / L. The detection rate of dental fluorosis in 400 children aged 8 ~ 12 was 29.25%, and the arithmetic mean of urine fluoride was 0.43 mg / L. The detection rate of dental fluorosis in 400 adults aged over 16 was 46.25%, and the detection rate of clinical skeletal fluorosis was 32.25 %; 400 adult urinary fluoride arithmetic mean 0.73 mg / L. Conclusion Li County is a tea drinking fluorosis poisoning area, to strengthen disease surveillance and health education is the key to prevention and treatment of tea-type fluorosis.
