摘要
目的掌握陕西省燃煤型氟中毒病情动态,评价防氟改灶效果。方法在监测点紫阳县柳良村测查8-12岁儿童氟斑牙和成人氟骨症患病情况,测定居室空气、玉米、辣椒含氟量和儿童尿氟水平。结果 2001-2003年儿童氟斑牙病情呈下降趋势,氟斑牙总检出率依次为87.93％、86．54％和78．79％,巾度以上氟斑牙检出率依次为58．62％、50．00％和39．39％,中度以上氟斑牙构成比依次为66．67％、57．78％和50．00％。儿童尿氟呈波动式下降(F=16．565,P<0．01)。3年来辣椒氟污染程度有所下降,室内空气、玉米氟污染未见减轻。结论防氟改灶是预防燃煤污染型氟中毒流行的有效措施,加强健康教育和炉灶管理工作是促使防氟改灶取得更好成效的重要环节。
Objective To investigate the tendency of coal-burning fluorosis and evaluate the effect of improving stoves on fluoride. Methods Dental fluorosis in children aged 8 - 12 years old and skeletal fluorosis in adults older than 16 years were examined in Liuliang village, Ziyang County, which was a national surveillance spot. Fluoride levels in indoor air,corn,chili and the urine of the children were determined. Results Child dental fluorosis went down gradually from 2001 to 2003. The total dental fluorosis rate were 87.93% ,86.54% and 78.79% in these consecutive years, respectively. Meanwhile, the rate of dental fluorosis of moderate and severe severity was respectively 58.62% ,50.00% and 39.39% and accounted for 66.67% ,57.78% and 50.00% of the total. The fluoride contents in the urine descended in fluctuation （F = 16,565,P 〈 0.01 ）. Fluoride content in chili, which was less polluted, had diminished during the three years, but that in the indoor air and corn had not decreased. Conclusions Improving stoves is an effective measure to prevent endemic fluorosis caused by coal-burning. Health education and the management of the improved stoves are important links insuring better effects.
