An update on chromium (VI) in leather methodology

The issue of chromium(VI) in leather has been debated for many years, but its significance has recently been raised due to newly proposed European legislation. The European Chemicals Agency (ECHA) has proposed (12/4/19 – Annex XV Restriction Report Proposal for a Restriction Substance Name(s): Skin Sensitising Substances) that the limit should be lowered from its current 3 ppm limit to 1 ppm, so that the leather industry is in line with the textile industry. While the textile industry uses little chromium, mainly in dyestuffs, the leather industry faces detecting 1 ppm of chromium(VI) in a background of 20,000-40,000 ppm of chromium(III).
