IMPACT OF ARTIFICIAL FLUORIDATION ON SALMON SPECIES IN THE NORTHWEST USA AND BRITISH-COLUMBIA, CANADA

A review of literature and documentation suggests that concentrations of fluoride above 0.2 mg/L have lethal (LC50) effects on and inhibit migration of ''endangered'' salmon species whose stocks are now in serious decline in the US Northwest and British Columbia. Fluoride added to drinking water, ''to improve dental health'', enters the fresh water eco-system, in various ways, at levels above 0.2 mg/L. This factor, if considered in ''critical habitat'' decisions, should lead to the development of a strategy calling for a ban on fluoridation and rapid sun-setting of the practice of disposal of industrial fluoride waste into fresh water.
