A Method to Distinguish Chromium-Tanned Leathers With Low and High Risks of Surface Hexavalent Chromium.

ABSTRACT:

Introduction

Traces of hexavalent chromium, Cr(VI), are a major concern for skin contact with Cr-tanned leather. Current extraction methods (ISO 17075-1:2017) for Cr(VI) testing do not necessarily reflect the true potential of surface-formed Cr(VI), as extracted concentrations are dependent on previous storage and atmospheric conditions.

Objectives

To test whether a spiking method protocol can distinguish leathers with high and low risks of releasing Cr(VI).

Methods

Two groups of leather types were selected based on previously detected Cr(VI) (group A) and optimal tanning practices with high antioxidants (group B), corresponding to a high and low risk of forming and keeping Cr(VI). Leathers were spiked with different concentrations up to 10 mg/kg of Cr(VI) and incubat
