The objective of this studywas to detect the fluoride level in the drinkingwater and the urine of habitantsaged 16–55 years living in Inner Mongolia China. Furthermore, fluoride concentration of the brick teainfusion samples which were drunk by Mongolia herdsmen in everyday life living in SumuErga village ofEjin Horo Banner, Inner Mongolia Chinawas also determined. A total of 117 participants (61 female and 56male) were recruited from two counties for a cross-sectional study on health effects of chronic fluorideexposure from drinking water and drinking brick tea infusion. The fluoride concentration in drinkingwater, urine and brick tea infusionsampleswere determined using fluoride ion selective electrodemethodobtained fromthe Ministry of Health of the People’s Republic of China. The average fluoride concentrationin drinkingwater sampleswas 0.32±0.01 mg/L at AretengXire town of Ejin Horo Banner, 0.70±0.19 mg/Lat SumuErga village of Ejin Horo Banner, and 2.68±1.15 mg/L at ZhalaiNuoer district of Manzhouli city. Theaverage fluoride concentration in brick tea infusion samples which collected from Mongolia herdsmen atSumuErga village of Ejin Horo Bannerwas 1.81±1.09 mg/L. The average urinary fluoride concentration atAretengXire town of Ejin Horo Banner was 0.59±0.48 mg/L, at SumuErga village of Ejin Horo Banner was1.45±0.93 mg/L and at ZhalaiNuoer district of Manzhouli city was 3.06±1.53 mg/L. The higher fluoridelevels in the urine of participants may be associated to higher fluoride in drinking water at ZhalaiNuoerof Manzhouli city. However, drinking brick tea infusions with higher fluoride may be the cause of thehigher fluoride contents in the Mongolia herdsmen’s urine.
