WHY IS CHROMIUM TANNING SO BAD?
One of the biggest potential dangers comes in the form of airborne hexavalent chromium VI, which can occur as the chromium III compound oxidizes during tanning. Hexavalent chromium VI is a known occupational carcinogen, causing lung, nasal, and sinus cancers, as well as skin irritation, ulcers and other physical symptoms. Workers in chrome tanning facilities in countries with little to no regulations suffer all of these symptoms, as well as considerable birth defects in future generations.
In addition to manufacturing pollution and lasting toxicity, chrome tanned leather has a much shorter lifespan than veg tanned, due to the weakened collagen structure from the tanning process. Even when well cared for, chrome leathers generally have a maximum life of 10 years before they begin to crack and degrade.
