The Science - Universities

Many Top Universities conduct research to help all of us begin to understand our world and environment while teaching.
Our understanding of our world, the science that help us with this understanding including healthy and considerate discussions and considering peoples beliefs and informed opinions are all important parts of healthy discussions.
The Precautionary Principal is one of many beliefs that help us apply the science as best as is possible, working toward helping each other.
"The precautionary principle denotes a duty to prevent harm, when it is within our power to do so, even when all the evidence is not in. This principle has been codified in several international treaties to which Canada is a signatory. Domestic law makes reference to this principle but implementation remains limited."

Hydrofluorosilicic Acid, the chemical used to fluoridate City of Prince George drinking water apparently dissociates a general process in which ionic compounds such as hydrofluorosilicic acid complexes or salts separate or split into smaller particles. When hydrofluorosilicic acid is added to our drinking water, it dissociates, creating hydrofluoric acid.
Hydrofluoric acid (HF) differs from other acids because the fluoride ion readily penetrates the skin, causing destruction of deep tissue layers, including bone.

Hydrogen fluoride is a gas which when in solution with water forms hydrofluoric acid, HF. Although a weak acid, i.e., it is not strongly disassociated, is used to etch glass. Like its sister, HCl acid, it reacts with water with the release of heat and can cause burns on the skin. Hydrofluoric acid has an even more detrimental effect that can affect many internal structures. Fatalities have been reported from a skin exposure to as little as 2.5% of body surface area. The weak disassociation allows it to be absorbed through the skin as the intact molecule.
All in all, fluoride from whatever source can be very dangerous."
