[edit] Confusion between the article and the talk page (title added)

The last edit should have been added to the discussion page instead of to the article itself, I suspect. —The preceding unsigned comment was added by Mq@maq.org (talk • contribs) .

[edit] Chromium in alloys is not hexavalent (title added)

Per my discussion with stainless steel suppliers who are involved in the European Directive for the reduction of hazardous substances, hexavalent chromium is NOT present in chromium-containing metals. There is chromium in these alloys, but it is NOT hexavaent chromium, therefore d) above is false.

This statement above was removed from the article owing to its style. Can anyone confirm its accuracy - if so, please edit the article to reflect that. Aussie Alchemist 23:25, 16 January 2006 (UTC)

According to Patty (4th Edition) hexavalent chromium particles are generated in the welding of stainless steel. The discussion in Patty mentions several studies of exposure to hexavalent chromium from these activities. It may be that hexavalent chromium is not present in the metal (as aserted by the stainless steel suppliers referenced above), but is produced from chromium of another valence during the welding process.

[edit] Carcinogenicity (title added)

"Some hexavalent chromium compounds are carcinogens."

I thought all hexavalent chromium compounds were carcinogenic. Should this be fixed? --71.227.190.111 03:48, 16 July 2006 (UTC)
