In China, more than 10 million people suffer from fluorosis caused by the burning of high fluoride coal. Analysis of the particulate matters of indoor air from these fluorosis areas reveals a logarithmic distribution of particle sizes. The levels of F- and SO4(2-) adsorbed or absorbed on the particles ranged from 16.27 to 46.18 micrograms/m3 and from 244.7 to 374.6 micrograms/m3, respectively. Gaseous and soluble fluorides constituted a considerable proportion of the inorganic fluorides. Nevertheless, the level of F- in air was considered to be inadequate to cause the observed severity of fluorosis. It is speculated that additional intake of F- from contaminated foods might also be a major factor contributing to the fluorosis. Additionally, some volatile elements (e.g., sulfur and its derivatives) might have some relation to fluorosis of this type.
在中国，超过1000万人患有因燃烧高氟煤导致的氟中毒。对这些氟中毒地区室内空气颗粒物的分析显示，粒径呈对数分布。颗粒上吸附或吸收的F-和SO4(2-)水平分别为16.27至46.18微克/立方米和244.7至374.6微克/立方米。气态和可溶性氟化物在无机氟化物中占相当大的比例。然而，空气中F-的水平被认为不足以导致观察到的氟中毒严重程度。据推测，从受污染食物中额外摄入F-也可能是导致氟中毒的一个主要因素。此外，一些挥发性元素（如硫及其衍生物）可能与这种类型的氟中毒有一定关系。
