饮茶型氟中毒病区主要食物氟含量调查分析

Analysis on fluoride content of main foods in drinking brick tea fluorosis areas Aba county sichuan province and chenbaerhuqi county Inner Mongolia.

目的 查明饮茶型氟中毒重点病区主要食物中的氟含量 ,旨在了解我国南、北方饮茶型氟中毒病区居民从食物中摄入氟的水平。方法 加热 -酸浸 -氟离子选择电极法和扩散 -氟离子选择电极法。结果 内蒙古饮茶型氟中毒病区与非病区主要食物氟含量比较差异无显著意义 (P >0 .0 5 ) ;内蒙古、四川两病区的主食和蔬菜氟含量差异有显著意义 (P <0 .0 1) ,但这些食物氟含量均值都低于国家制订的食物氟允许量 1～ 1.5 mg/ kg。结论 饮茶型氟中毒病区居民主要食物中的氟含量不是构成氟中毒的主要致病因素。

Objective Determine fluoride content of main foods in drinking brick tea fluorosis areas,and know intake of fluoride level of the residents living in drinking brick tea fluorosis areas from foods.Methods Heating acidic immersion FISE method,and diffusion FISE method. Results There was no significant difference of fluoride content of main foods in the endemic drinking brick tea fluorosis area as compared with that of nonfluorosis area in Inner Mongolia(P>0.05).The difference of fluoride content of foods in endemic fluorosis areas,Aba county,Sichuan province Inner Mongolia Chenbaerhuqi county was singrificant,but mean of fluoride content of these foods was lower than that of permitted amount worked out by China (1~1.5mg/kg).Conclusions Fluoride level of main foods were not main source of intaking fluoride of residents living in the endemic drinking brick tea fluorosis area.
