目的探讨湖南中部燃煤型氟中毒病区氟的来源,为制定地方性氟中毒的预防措施提供理论依据。方法2006年11月,调查了湖南中部地区新化县氟中毒病区村和对照村小学五年级(10～12岁)学生氟斑牙患病率,按患病率的高低分为病区一组、病区二组和对照组。用氟离子选择电极法测定各组饮用水、原煤、蜂窝煤、煤灰、拌煤粘土和空气氟含量,计算蜂窝煤在燃烧时的氟释放量。结果3组居民的饮水氟含量差异无统计学意义(F=3.359,P>0.05),且病区与非病区均低于1.0mg/L。3组居民的原煤、煤灰的氟含量差异无统计学意义(P>0.05)。病区组空气氟含量虽高于对照组,但差异无统计学意义(P>0.05)。3组居民的蜂窝煤、拌煤粘土...

Objective To explore the origin of fluoride in the coal-combustion endemic fluorosis areas in the middle part of Hunan Province and to provide basic data for making preventive measure in the regions. Methods In November, 2006, the prevalence rate of dental fluorosis of children aged 10-12 years were examined, the villages were divided into three groups based on the prevalence rate of dental fluorosis. The fluoride content in the drinking water, coal, briquettes, briquette ash, clay and indoor air was determined by fluoride ion selective electrode. The quantity of fluoride release was calculate...
