Major concern for the leather industry is the analyzed presence of toxic Cr (VI) traces in Cr (III) tanned leathers. Origin of the contamination is unknown, but the fact is that Cr (III) tanned leather products fail to pass upper accreditation limits of Cr (VI). The level of sector interest demands an appropriate methodology to develop a detailed understanding whether or not there really is Cr (VI) contamination in commercial leathers. If there is, the contamination must be avoided. In other case, the future of the worldwide industry that supplies nearly 85 % of leathers as Cr (III) tanned one will be under much stronger pressures by strict environmental legislations, health safety regulations and customer acts. The project will elucidate the origin of Cr (VI) traces in the leather, develop reliable official testing methods and evaluate current production technology and methodologies to avoid such a contamination in their end products.
