| Résumé : |
Chromium is the most widely used tanning agent. For the tanner it is easy to use and produces high quality leather. By different retannages and other treatments it is possible to produce quite different leathers, starting from the same chrome tanned stock. Thus chrome tannage is very versatile and shortens the response time of the tanner to the demand for a new leather type. So, from the point of view of a tanner, chromium as a tanning agent has almost only advantages and he will be very reluctant to substitute it by any other tanning agent.
Unfortunately, chromium is a heavy metal and thus under environmental scrutiny. Some chromium compounds ar toxic and even carcinogenic. Thus legislation has developed to restrict the discharge of chromium into the waste water and into dolid wastes. Consequently the tanner is obliged to undertake appropriate actions.
In the following a short excursion on the legislation on chromium will be given, the sources of discharge from the tannery and measures for restricting it will be discused and then the relevance of chromium as an environmental hazard will be estimated.
2. Legislation on chromium containing.
3. Sources of discharge of chromium into tannery effluents.
4. Measures to reduce the chromium discharge.
5. Relevance of chromium as an environmental hazard. |
