The most interesting tidbit in the article was this:
About 90 percent of the fluoride that is added to the water takes the form not of pharmaceutical grade sodium fluoride but ... fluorosilicic acid ... This material is a byproduct of phosphate fertilizer manufacturing ... several studies have suggested that this form of fluoride can leach lead from pipes. ...other work shows that children in fluoridated areas have elevated blood lead levels, and fluoride may also increase the absorption of lead into the body... Lead itself is a potent neurotoxin and has been shown to play a role in ADHD.
What is the likelihood that in areas with lower spending on municipal water that lead pipes are still used and they use the cheapest for of fluoridation available?
This freaks me out a little.
- kevin_thibedeau 12y agoThe concern over lead in the water system is largely focused on lead-based solder in copper pipes. That is restricted largely to postwar homes up until the emergence of PVC and PEX plumbing in the 80's.
- fulafel 12y agoPlastic pipes can put endocrine disruptors like BPA/BPS and other nasties in the water. It's pretty common for new piping to leave noticable odor/taste for a while. For "other nasties" see http://grist.org/living/is-it-safe-to-drink-water-out-of-plastic-pipes/ http://grist.org/living/is-it-safe-to-drink-water-out-of-pla... "Some of the latest research coming out of the NSF project tested several brands of PEX tubing for chemical leaching – and found it."
