Özet
In this study the heavy metal toxicity of finished leather has been analyzed using enzyme activity inhibition bioassay, the MetPLATE and heavy metal contents of the samples were compared by % inhibition levels. The toxicities of soluble forms of heavy metals in leather were revealed by analyzing leather samples in the artificial alkali sweat solution and the toxicity characteristic leachate procedure solution (TCLP). Total heavy metal concentrations of finished leather have been determined by means of Inductively Coupled Plasma Optical Emission Spectrometry (ICPOES). According to the test results obtained, the heavy metal toxicities of finished leather, especially in terms of chromium, have been found at above the critical limits. % inhibition levels of the finished leather samples were found to be in the range of 13.20-99.35%, which mainly came from chromium, cobalt and copper.
