对豫西不同生活水平的４个产煤村空气氟污染状况进行调查，结果室内空气氟含量分别为国家标准０．００７ｍｇ／ｍ３的１．４９－２．８６倍，而烧柴和燃用外购蜂窝煤的对照村空气氟含量未超标。产煤村８－１２岁儿童氟斑牙率显著高于对照村，其中３个村达到氟病区标准，证实空气氟污染是形成燃煤型病区的主要氟源。但经济状况好，住室宽敞的产煤村儿童牙齿损害程度轻或氟斑牙率达不到病区标准，提示生活水平与居住条件是影响燃煤型氟中毒发生的一个重要因素。
Investigation on the fluorine contamination of air in 4 coal-producing villages with different living standards in western Henan showed that fluorine content in indoor air was 1.49-2.86 times that of the national standard of 0.007mg / m3, respectively. Controlled village purchase of coal air fluoride content is not exceeded. The rate of dental fluorosis among children aged 8-12 years in coal-producing villages was significantly higher than that in control villages, of which 3 villages reached the standard of fluorine-affected areas and confirmed that air fluorine pollution was the main fluorine source for forming coal-burning ward. However, the economy is good, the spacious coal-burning village children with dental injury or dental fluorosis rate of less than the ward standard, suggesting that living standards and living conditions are an important factor affecting the occurrence of coal-fired fluorosis.
