目的 总结和分析燃煤污染型地氟病监测中的问题,为巩固和推广改灶防氟已取得的防治成果提供科学资料。方法 按国家规定的统一方法对监测点的监测结果进行对比。结果 两个监测点室内空气氟,初次检测均值分别为0.0074、0.0054m g/m 3,7年后为00018、00039m g/m 3。室内存放玉米氟含量,初次为195、3021m g/kg,7年后为14.05、30.95m g/kg。辣椒氟含量,初次为28364、67393m g/kg,7年后为46565、41982m g/kg。儿童尿氟,初次为224、418m g/ L,7年后为246、336m g/ L。氟斑牙检出率,初次为945% 和100% ,7年后为539% 、899% 。两监测点炉灶维修巩固率分别为72% 和36% ,两者差异有显著性意义。结论 监测点氟污染仍然严重。通过辣椒摄氟将成为主要流行途径。炉灶维修巩固率决定了改灶防氟的长期效果,亦说明了改灶防氟的重要性,应加强宣教与管理的投入。
Objective To summarize and analyze the problems in the monitoring of groundwater contamination due to coal-burning, and provide scientific information for consolidating and popularizing the prevention and cure results of the prevention and cure of stoves. Methods According to the unified method stipulated by the state, the monitoring results of monitoring points were compared. Results The mean values of fluorine in the air at the two monitoring points were 0.0074,0.0054m g / m 3 for the first time and 00018,0,0039m g / m 3 after 7 years respectively. Indoor storage of corn fluorine content, the first was 195,30 21m g / kg, 7.05 years after the 14.05,30.95m g / kg. The fluoride content of chili pepper was 28364 and 67393 m g / kg for the first time, 46565 and 41982 m g / kg after 7 years. Urinary fluoride in children, for the first time was 2 24, 4 18m g / L, 7 years after 2 46,3 36m g / L. The detection rate of dental fluorosis was 94.5% and 100% for the first time, 53.9% and 89.9% after 7 years respectively. Two monitoring points stove repair consolidation rates were 72% and 36%, the difference was significant. Conclusion Monitoring points fluorine pollution is still serious. Fluorine uptake by chili will be the main epidemic route. Stove repair rate of consolidation decided to change the long-term effect of fluoride stove, but also shows the importance of Fluorine to the stove, should increase investment in mission and management.
