奎屯垦区1960年以前饮用河渠水,60年代开始该垦区大力打井开发利用地下水。在改善水质,降低肠道传染病的同时,发现井水中含氟量过高,居民出现严重的地方性氟中毒,以126团场,127团场反映最严重,个别井水含氟量高达20毫克/升以上(我国饮用水卫生标准氟化物含量不超过1毫克/升)。一、高氟区的范围和形成高氟区的机理 1.调查奎屯各种饮用水水中氟的含量,确定奎屯的车排子地区为一高氟区,该高氟区为第4纪亚砂土质冲积平原。井水含氟量高是由于流水通过该土质将氟化物不断由高处冲刷至
Kuitun reclamation area before 1960 drinking river water, 60 years began to reclamation area vigorously drilling to develop and use of groundwater. While improving water quality and reducing intestinal infectious diseases, it was found that the fluorine content in well water was too high and residents suffered from serious endemic fluorosis. The highest level was reported in 126 groups and 127 groups, and the fluorine content in individual well water was as high as 20 Mg / l or more (China’s drinking water health standards fluoride content does not exceed 1 mg / l). First, the scope of high-fluorine zone and the formation of high-fluorine zone mechanism 1. Investigation of Kuitun various drinking water fluoride content to determine the Kuitun car Paizi region is a high-fluorine zone, the high-fluorine zone for the 4th member of the Asian sand Soil alluvial plain. The high fluorine content in well water is due to the continuous flow of fluoride through the soil to a high level
