2009 The Effects of Fluoridating Agents on the Chemistry of Thunder Bay

Drinking Water.

"The experiments measured the amount of lead leached into solution from the

[lead] coupons immersed in the solution of the fluoridating agent."

"The fluoridating agent that caused the greatest amount of lead leaching was

the solution of un-buffered hydrofluorosilicic at a concentration of 0.7

ppm.. The rate was about 2.6 times the control."

"The findings show that all the fluoridating agents chosen increase the

corrosion of lead pipe-"

Conclusion

"Addition of fluoridating agents to the water, especially hydrofluorosilicic

acid would increase this tendency and hence increase lead levels at the

consumer tap."

Please send to your local council, water operators, environmental groups, social justice groups, and whoever else you feel should see this.
