CiteSeerX — FLUORIDE EXPOSURE FROM BURNING

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): SUMMARY: The very high prevalence of dental and skeletal fluorosis in relation to the fluorine content of local coal and clay was investigated in two rural re-gions with low water fluoride (Hualuo Village and Majianzhuang Village) of Guizhou Province, China. The fluorine content of coal in the two regions is con ...

Health effects of fluoride pollution caused by coal

2001-4-23  1. Introduction. Fluoride compounds are found in a wide range of concentrations in coal, soil, ground water, sea water, minerals, plants and animals (UNEP/ILO/WHO, 1984, Symonds et al., 1988).Coal is the most abundant fossil fuel resource worldwide, therefore, a huge amount of hazardous chemical components including fluorides have been released into the environment by combustion of coal
