Sažetak
People are exposed to chromium ions from leather materials due to the every day s contact with different textile objects. The problem is the fact that chromium(VI) is extremely toxic and may cause contact allergic dermatitis on the skin and also be a trigger for many diseases. Huge amounts of chromium ions are released by wastewaters to rivers after chromium– tanning processes in leather industry, and by this chromium presents not only a problem for human health but also for the environment. For this reason it is extremely important to monitor the presence of chromium as chromium (VI) and total chromium. This study aims to present an appropriate analytical method for monitoring chromium(VI) and total chromium present on leather materials. Applying this method o chromium tanned leather samples, it was observed that the amounts of total chromium as well as chromium(VI) are higher than prescribed and recommended by different standard methods. Chromium(VI) exceeded the limit of 3 mg/kg in majority of tested materials while the total chromium exceeded the limit of 50 mg/kg in all tested samples. For this reason it is recommended to avoid direct and prolonged contact of those materials with the skin.
