Environmental Consequences of Fluoridation – I – Fish

Environmentally, consequences of fluoridation and other forms of fluorination can be extremely devastating and are indeed proving to be very deleterious to the environment, especially to fish.

There are … studies that indicate that fluoride at levels below 1.5 mg/L have lethal and other adverse effects on fish. Delayed hatching of rainbow trout occurred at 1.5 mgF/L11; brown mussels died at 1.4 mgF/L12; an alga (Porphyria tenera) was killed by a four-hour fumigation with fluoride with a critical concentration of 0.9 mgF/L13; and, levels below 0.1 mgF/L were shown to be lethal to the water flea, Daphnia magna14. These latter two studies suggest that salmon species may be affected by fluoride induced reduction of food supply.

Documents used in the Court case involving Meader’s Trout farm in Pocatello, Idaho, in 196115 contain evidence that between 1949 and 1950 trout damage and loss was related to fluoride contamination due to rain washing air-borne particles from leaves into hatchery water at levels as low as 0.5 mgF/L.

Therefore, there is evidence that the “safe level” of fluoride in the fresh water habitat of salmon species is not 1.5 mg/L but, 0.2 mg/L.

In fluoridated areas, drinking water, obtained from surface water with an average fluoride concentration of 0.1-0.2 mg/L16, is raised to the “optimal” level of 0.7-1.2 mgF/L by the addition of sodium fluoride, hydrofluosilicic acid, or sodium silicofluoride. Fluoride, in community drinking water, enters the fresh water ecosystem in various ways. Surface run-off from fire-fighting, washing cars, and watering gardens may enter streams directly or through storm sewers at optimal concentration, 0.7-1.2 mgF/L. Most enters during waste water treatment.

The effects in rivers and lakes to both flora and fauna are therefore seen as both toxic and pervasive. By changing the Ph level of water, fish and their source of food are poisoned by water borne fluoride substances and create an environmentally unsound milieu for their eventual survival. If this situation is not reversed, we are faced with many irreversible consequences to our own survival as a species if we continue to allow the poisoning of our environment by the use of silicofluorides and other fluorinating substances.
