【摘要】 [目的]通过对青海省黄南州人群氟中毒的调查,分析掌握该地区氟中毒特征。[方法]在该地区进行现场流行病学调查,用氟离子电极检测氟化物,用Dean氏法检查氟斑牙,临床氟骨症诊断按国标(GB16396-1996)进行。[结果]氟含量年龄段均值:水源的水氟含量在0.22～0.29mg/L之间(国家标准﹤1.0mg/L),茶水氟含量在1.34～1.54mg/L之间,尿氟含量在1.03～1.77mg/L之间,50岁以上人群的尿氟含量超标(WS/T256-2005)。随着年龄的增加,人群的尿氟含量递增,成人的尿氟含量高于儿童(t=1.9610,P﹤0.05)。小于40岁的人群,茶水氟摄入量与尿氟排出量之差减少。各年龄段氟斑牙检出率随年龄的增加而降低,氟骨症检出率则随年龄的增加而升高。[结论]黄南州氟中毒特征与国内对饮茶型氟中毒的研究结果类似。更多还原

【Abstract】 [Objective] To study the characteristics of fluorosis through fluorosis investigation in Huangnan crowd in Qinghai province. [Methods] By field epidemiology investigation in this area, fluoride detection was detected by fluorine ion electric, the mottled enamel was examined with Dean index, clinical osteofluorosis was diagnosed according to national standard (GB 16396-1996). [Results] The average fluoride content of each age group was as follows: fluoride in drinking water was between 0.22 and 0.29 mg / L, in boiled water was between 1.34 and 1.54 mg / L, and urine fluoride was between 1.03 and 1.77 mg / L, urine fluoride of crowd above 50 years exceeding standard (tWS / T256-2005). Fluoride content of crowd increased with aging, the fluorine level in adult urine was higher than that in children urine (t = 1.9610, P﹤0. 05). Among people below 40 years, ?the difference of fluoride in boiled water intake and urine fluoride showed to be reduced. The positive rate of dental fluorosis of each age group reduced with aging, but the positive rate of osteofluorosis increased with aging. [Conclusion] The features of fluorosis are similar with the previous studies on the fluorosis in Huangnan and the other fluorosis area.更多还原
