Dear

Compare this to the 170 grams a day of wheat and grain products typically consumed, 40% of which may have been fumigated with sulfuryl fluoride. When the concentration in that fumigated wheat averages 60 ppm, it yields a dose of 4 milligrams of fluoride which is the same dose as consuming one liter of water at 4 ppm i.e. half the reference dose. ................
