摘要
目的提出燃煤污染型氟中毒病区控制指标，使病情得到有效控制。方法采用以改炉灶为主，降低室内空气氟、食品氟含量。结果病区室内空气氟和玉米氟Ｍ值由防治前的２９．００μｇ／ｍ３及８．３５ｍｇ／ｋｇ降至０．１９μｇ／ｍ３及０．２４ｍｇ／ｋｇ；居民日摄氟量由６．９５ｍｇ降至０．６２ｍｇ；人群尿氟均值中、轻度病区由５．３０、１．４２ｍｇ／Ｌ降至０．９０、０．５３ｍｇ／Ｌ；８～１２岁人群氟斑牙率中、轻度病区由５０．７０％、３２．９２％降至１４．７３％、４．３６％。结论以改炉灶为主的综合措施，能有效控制燃煤污染型氟中毒，并提出了病区控制指标。
Objective Put forward fluorosis disease control index in coal burned polution endemic fluorosis areas.Methods Improving stove to decrease fluoride in indoor air and food.Results The fluoride value in indoor air and corn were decrease from 29μg/m 3 and 8.35mg/kg to 0.19μg/m 3 and 0.24mg/kg after the stove was improved;daily fluoride intake was decreased from 6.95mg to 0.62mg among resident;urinary fluoride in light and middle severe fluorosis areas were decreased from 1.42mg/L and 5.3mg/L to 0.53mg/L and 0.9mg/L;dental fluorosis among children 8￣12 years old in light and middle severe fluorosis areas were decreased from 32.92% and 50.7% to 4.36% and 14.73%.Conclusions Coal burned polution endemic fluorosis can be prevented by improving stove,and related index was put forward.
