Dear Dr. Godwin. hgodwin@ucla.edu

Your article on lead poisoning is excellent.

You mentined “lead-contaminated drinking water in Los Angeles Unified School District (LAUSD) school” and that “the local media reported in 2008 that several drinking fountains in elementary schools in the LAUSD contained water with lead levels higher than the national standard for drinking water”. However, you said nothing about one of the major sources of lead intake, lead in dental chemicals added to drinking water and leaching of lead from pipes by dental chemicals.

Fluorosilicic acid not only contains lead. It also breaks down into silicic acid, which leaches lead from pipes, and there is a lot of lead in old plumbing. Even new brass pipes and faucets can contain up to 8% lead in states other than California. Old buildings can contain pipes which are up to 30% lead. In 2004 Seattle papers  reported lead at up to 1,600 ppb  in drinking water in Seattle schools, a shocking level, far above the 15 ppm EPA action level for lead and the 0 ppm goal.

I wish you had said more also about lead bullets and leaded avgas.

Rick Nevin’s article in Mother Jones about lead and crime also failed to go into the connection between dental chemicals and lead poisoning.

If you had gone into the connection between lead and dental chemicals, you you might get in trouble, as did Phillis Mullinix, who was fired for doing so. It is a sacred cow. Your university may be getting money from the chemical companies which sell dental chemicals.

“Oh, it’s just a little bit of lead”, I hear from supporters of dental chemicals. No it isn’t just a little bit. There is no safe amount of lead which we should be ingesting.

Sincerely,
