• Health effects of fluoride pollution caused by coal

    As summarized in Table 1, combustion of coal and coal bricks which are highly contaminated with fluoride, releases gaseous and aerosol fluoride into indoor airAirborne fluoride especially gaseous fluoride was relatively high (825±92%), fluoride was easily absorbed by uncovered food that was being dried for storage on the ceiling upon a coal stove

  • Health effects of fluoride pollution caused by coal

    Inorganic phosphate concentrations in urine were significantly lower in the residents in fluorosis areas in China than in nonfluorosis area in China and Japan Since airborne fluoride from the combustion of coal pollutes extensively both the living environment and food, it is necessary to reduce fluoride pollution caused by coal burning
