我国新修订的生活饮用水卫生标准规定:每升水中氟化物含量不可超出1毫克。可是,华北、东北和西北一些地方的地下水(浅井、探井或温泉)的天然含氟量过高,导致居民发生饮水型地方性氟中毒——当地生长的儿童患不同程度的氟斑牙,如果人们长期饮含氟量5毫克/升以上的水就可能出现骨关节疼痛、骨关节运动功能障碍,甚至关节变形和脊柱弯曲等氟骨症。这种慢性病使患者身心受到沉重折磨,十分痛苦。
China’s newly revised drinking water health standards: per liter of water fluoride content can not exceed 1 mg. However, the natural fluorine content of groundwater (shallow wells, exploration wells or hot springs) in some parts of North, Northeast and Northwest China is too high, leading to endemic fluoride poisoning in drinking water - local children with dental fluorosis have different degrees of dental fluorosis Long-term people drink more than 5 mg / L of fluoride in the water may appear bone and joint pain, osteoarthritis dysfunction, and even joint deformity and spinal curvature and other skeletal fluorosis. This chronic disease makes the body and mind severely tortured, very painful.
