我区北依太行,南临黄河。西部,北部山区的荧石矿、火山岩是重要的氟源;干旱、半干旱的气候条件有利于地下水中氟的浓缩;东部的苏打盐渍土壤也为氟的活化提供了有利的化学环境。以上因素决定了:我区局部地区高氟地下水的形成。当地居民由于长期饮用高氟水,大量氟在体内积累引起了不同程度的地方性氟中毒,严重地危害了人民健康。配合氟病调查,我们对病区饮水进行检测,共检水样1033份,根据国家饮水卫生标准(含氟量为0.5—1.0mg/L),其中664份超标,占总水样的64％,含氟量最高者达
My area north Taihang, south of the Yellow River. The fluorite and volcanic rocks in the western and northern mountainous areas are important fluorine sources. The arid and semi-arid climatic conditions are favorable for the concentration of fluorine in groundwater. The soda saline soils in the east also provide a favorable chemical environment for the activation of fluorine. The above factors determine the formation of high-fluoride groundwater in some areas of our region. Due to long-term consumption of high-fluoride water by local residents, a large amount of fluorine accumulated in the body caused different degrees of endemic fluorosis and severely endanger people’s health. With the investigation of fluoride disease, we test the ward drinking water, a total of 1033 water samples, according to the national drinking water health standards (fluorine content of 0.5-1.0mg / L), of which 664 exceed the standard, accounting for 64% of the total water samples, , The highest fluorine content of up to
