I ran across a very interesting website called Corrosion Doctors at www.corrosion-doctors.org/.

“The mission of this popular Web site is to improve the general awareness of what corrosion is all about, from complicated processes that are at play even behind the simplest corrosion reactions to the impact corrosion may have on systems (pipelines, cars, boats, …) and human health (implants, allergies, toxic metals …).

“Many are surprised when they learn that there are many ways to prevent and control this natural force. The Corrosion Doctors’ visitors are also surprised when they learn that these corrosion processes may also be happening inside their own body!! However, the topics covered in the many pages of the Web site go much beyond metallic corrosion because Corrosion Doctors also discuss the degradation of our lives due to toxic elements and the basic degradation of the planet because of pollution, global warming, and global dimming! With more than 1,600 pages and thousands of external links, the Corrosion Doctors site is a good example of what lean information systems are about.”

This is an amazing research site. One page has a graphic of the Periodic Table of Elements that shows which are toxic and which are not. The toxic ones are: Arsenic, Beryllium, Cadmium, Chromium, Cobalt, Copper, Fluorine, Lead, Mercury, Nickel, Thallium.

I’ve bookmarked this site so I can study it more. It’s the best place I’ve found to go for information on metals toxicity.
