Many factors in the tanning process such as vegetable retanning or chrome leachability in the buffer prescribed by EPA in the Toxicity Characteristic Leaching Procedure (TCLP), and presumably, therefore, in land disposal scenarios where natural forces are at work. A number of simple additions or treatments have been conducted on blue shaving in order to observe the impact upon chromium leachability in the specific conditions required by the TCLP. These observations are offered in the hope that process design and waste treatment might beneficially draw upon this knowledge for greater environmentally responsible operation.

Mold strains isolated from unfinished and finished leather goods and shoes / Meral Birbir in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXIX, N° 1 (01/1994)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXXIX, N° 1 (01/1994) . - p. 14-19 Titre : Mold strains isolated from unfinished and finished leather goods and shoes Type de document : texte imprimé Auteurs : Meral Birbir, Auteur ; Oguz Ozyaral, Auteur ; Candan Johansson, Auteur ; Atilla Ilgaz, Auteur Année de publication : 1994 Article en page(s) : p. 14-19 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : A series of Turkish leather samples ranging from freshly prepared chrome tanned blue crust to new and used shoes was examined for fungal contamination. Sixty two pieces of fungi from 23 genera were isolated and identified. These included Absidia, Acremonium, Aspergillus, Basipetospora, Emericella, Eupenicillium, Eurotium, Fusarium, Monascus, Moniliella, Mucor, Neosartorya, Paecilomyces, Penicillium, Phialophora, Scopuloriopsis, Stachybotrys, Trichoderma, Trichosporon, and Verticillium. Eighteen of these species were found to be mycotic agents capable of causing primary skin infection. Aspergilli et Penicillia species were found on chrome tanned leathers and shoes. The number of mold species isolated increased with time of storage particularly under humid conditions. Fifty three percent of the species found on stored unused shoes were also isolated from used shoes. This suggests that some mycotic infections could be due to the contamination of finished leather during storage or from the shoes contamination during the shoe making process.
