mass body (poisonous level) → g F- (conversion factor) → mg F- (concentration) → L water
Fluoride ion is poisonous in relatively low amounts: 0.2 g of F − per 70 kg of body weight can cause death. Nevertheless, in order to prevent tooth decay, F− ions are added to drinking water at a concentration of 1 mg of F− ion per L of water. How many liters of fluoridated drinking water would a 70-kg person have to consume in one day to reach this toxic level? How many kilograms of sodium fluoride would be needed to treat an 8.50×107-gal reservoir?
