Learn MoreHexavalent chromium has been concluded to be a human carcinogen by the inhalation route of exposure as identified on IRIS USEPA 2016b. For hexavalent chromium IRIS provides an inhalation cancer toxicity value for potential inhalation carcinogenic effects and an oral RfD and inhalation noncancer toxicity value or reference concentration RfC.
Read MoreChromium VI also known as Hexavalent Chromium can be an undesirable byproduct of chrome leather tanning. It can be formed in leather through the oxidation of Chromium III compounds that occur within or after the tanning process from inadequate chemical treatment during finishing or due to environmental conditions.
