吉林省延边地区氟病呈灶状分布,病区属冷、温泉混合饮水型。在氟病区6～19岁人群中调查了氟斑牙患病率,对成人中氟骨症进行了X线拍片检查,发现氟斑牙3392例(61.10％),氟骨症8例(12.30％)。饮水氟1.5mg/l的地区可流行氟骨症。改水后(0.68mg/l)虽然病情减轻和减少,但仍有发病。我们认为现行饮水含氟量标准偏高,应降为0.5mg/l左右,将上限定为0.7mg/l,下限定为0.3mg/l合适。
Yanbian area in Jilin Province was characterized by focal distribution of Fluorosis, ward is cold, hot spring mixed drinking water. The prevalence of dental fluorosis was investigated in people aged 6-19 in the endemic fluorosis area. X-ray film examination of skeletal fluorosis in adults revealed 3392 (61.10%) cases of dental fluorosis and 8 (10.3%) cases of skeletal fluorosis %). Fluoxetine is available in areas with a fluoride of 1.5 mg / l. After changing the water (0.68mg / l) although the condition to reduce and reduce, but there is still disease. We think the current drinking water fluoride standard high, should be reduced to about 0.5mg / l, the upper limit of 0.7mg / l, the lower limit of 0.3mg / l appropriate.
