Hello
Hexavalent Chromium can cause not only contact dermatitis but also many other malignancies. I always thought Chromium is something that can be ingested or inhaled only in special environment (such as welding industry or chrome plating industry). But I recently found out that chromium salt is commonly (almost 80% of the leather tannery) used in tanning process (thus called chrome tanned leather).
Trivalent chromium, which is used in tanning process, does not pose any harm on human body...
