Tannage Résumé : The presence of the adsorbable organic halides (AOX) in treated Spanish tannery effluents has pushed us to investigate the source and origin of these contaminants from the tanning process. The auxiliary products containing organohalides used in the fatliquoring bath seem to be the main source of adsorbable organic halides in the wastewater. However, important concentrations of adsorbable organic halides have been found in other process wastewaters, and they are not eliminated in the physical and chemical wastewater treatments. Nevertheless, the source of these adsorbable organic halides is unknown. Thus, the main objective of this study was to carry out determinations of AOX and some other physical and chemical parameters of the wastewater generated in the tanning plant to characterise the wastewater of each process. The results reveal that the most important sources of AOX are the fatliquoring, tannage and pickling baths.

In this study, EC50/LC50/LC50 for several cationic softeners, in both emulsions and microemulsions, were estimated through bioassays (Photobacterium phosphoreum) and aquatic biota (Chlorella vulgaris, Scenedesmus subspicatus, Selenastrum capricornutum, Daphnia magna and Oncorhynchus mykiss). The results obtained from the different bioassays were compared and their implications for toxicity monitoring were assessed.
