摘要
目的了解某市A、B两县燃煤污染型氟中毒改灶降氟干预措施实施情况及短期效果。方法于2007年4—6月,在38000户改灶农户中,按照2%抽样比进行整群抽样,选择了769户,采取入户调查方式对地氟病改灶综合措施卫生灶正确使用情况和设施合格情况进行调查;并从中随机抽取70户改灶户检测其空气、粮食、副食品中氟含量。结果A、B两县改灶降氟卫生灶正确使用率为98.7%,但设施合格率低于80%。A、B两县空气氟平均浓度为0.0037mg/m3,玉米氟含量超标率分别为18.75%和22.22%,辣椒氟含量超标率分别为67.5%和65%。结论燃煤型氟中毒病区卫生灶正确使用率较高。辣椒、茶叶的氟污染已成为防治氟中毒的主要问题。应加强对改灶的后期管理。
Objective To know the implementary circs and short-dated effects of cooking stoves improvement in reducing fluoride level in the endemic fluorosis areas and to offer the background information and scientific basis for continuing the development of cooking stoves improvement in reducing fluoride level. Methods To do the surveys in the households, 769 families were selected and investigated from 38 000 peasant families in the program, by cluster sampling with 2% sample rate and 70 families were randomly selec...
