Abstract:
Objective To explore the epidemic factors for dental fluorosis of residents living around an aluminum smelter plant. Methods The contents of fluoride in 1 575 urine samples, some drinking water samples collected from the centralized water supply systems, springs and wells water, wheat, Chinese cabbage, soil and air samples were determined. The epidemic situation of dental fluorosis in 1766 residents was investigated according to the unique national standard. Results The concentration of urine fluoride [(1.913?1.413) mg/L] of 1 575 residents living around an aluminum smelter plant was higher than that (about 0.5 mg/L) in non-endemic area, the prevalence rate of dental fluorosis was 90.09%. The contents of fluoride in wheat, Chinese cabbage and soil did not exceed the related limits or background values. The concentration of fluoride in air samples exceeded the Grade II limit of Environment Air Quality Standard by 0.04-2.73 times. Conclusion Air fluoride pollution and drinking tea water containing higher concentration of fluoride are considered as the one of the factors that may cause dental fluorosis of the residents living around this aluminum smelter plant.
