Règlements de sécuritéIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The author sums up the latest EU regulation around chemical compliance.
The EU regulation that aims to protect human health and the environment through registration, evaluation, authorisation and restriction of chemical substances (REACH) is well underway. A chemical thought to cause harm to the environment or human health may be labelled as a Substance of Very High Concern (SVHC). For the leather industry, European regulators and consumers are concerned about chemicals with the following properties:
- Carcinogenic - chemicals that cause cancer in living tissue
- Mutagenic - an agent that can cause genetic mutations
- Teratogenic - a chemical that can affect embryo growth
- Reprotoxic - a substance that can harm an organism's reproductive system, directly affecting sexual function and fertility
- Persistent - a substance not easily degraded in the environment
- Bio-accumulative - a substance that accumulates in biological tissues
Identified SVHCs are added to a list known as the Candidate List and, after their evaluation, these substances are included on the Authorisation List (Annex XIV), the Restriction List (Annex XVII), are kept on the candidate list, or are dropped of any REACH list completely. Substances can appear on more than one list. The Authorisation List places controls and restrictions on chemicals that are used or sold into the EU.Note de contenu : - New chemicals on the candidate list

Produits chimiques -- BiodégradationIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather processing is associated with the employment of many kinds of chemicals which may be used to excess. As a result, a part of the chemicals inevitably remain in the tannery wastewater and form major pollutants. Biological treatment plays a significant role in removing these chemicals from wastewater and biodegradability of these chemicals is directly related to their environmental friendliness. Recently, we have been undertaking a systematic evaluation of the biodegradability of typical leather chemicals so as to characterize their environmental impact as exactly as possible. In this paper, the biodegradation behaviours of six typical fatliquor components, including sulphated castor, sulphated neatsfoot oil, sulphated fish oil, lecithin, chlorinated paraffin and alkyl sulfonyl chloride, were investigated. It has been found that four of them, sulphated castor, neatsfoot oil, fish oil and lecithin, can be effectively degraded by the activated sludge from the wastewater treatment plant of the tannery, which suggests that these four kinds of fatliquors are suitable for use in leather making in consideration of their environmental friendliness. However, the two other kinds of fatliquors, chlorinated paraffin and alkyl sulfonyl chloride, cannot be degraded by activated sludge and the presence of alkyl sulfonyl chloride in wastewater will lead to poisoning of the activated sludge, which indicates that these two kinds of fatliquors should be limited in use.

Agents de tannage
AldéhydesUn aldéhyde est un composé organique, faisant partie de la famille des composés carbonylés, dont l'un des atomes de carbone primaire (relié au plus à 1 atome de carbone) de la chaîne carbonée porte un groupement carbonyle.
L'aldéhyde le plus simple est le formaldéhyde (ou méthanal), aussi appelé formol lorsqu'il est en solution aqueuse.
Un aldéhyde dérive formellement d'un alcool primaire (oxydation) dont le groupement hydroxyde -OH est en bout de chaîne et se forme suite à l'enlèvement de deux atomes H d'où le nom "alcool déshydrogéné" ou aldéhyde.

SyntansIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The biodegradability of typical organic tanning agents, including aromatic syntans, aldehydic tanning agents and acrylic tanning agents, were investigated. The results showed that the biodegradation behaviours of these leather chemicals are closely associated with their chemical structures, molecular weights and compositions. Therefore, different organic tanning agents might result in different environmental impacts even though they belong to the same type of tanning agent. The four aromatic syntans tested exhibited low biodegradability in general. Among them, a phenol-based syntan was not biodegradable and the phenol-sulphone based syntan produced a strong inhibitory effect on respiration of activated sludge. Comparatively, the naphthalene-based syntan was somewhat easier to biodegrade than other aromatic syntans. In the cases of aldehydic tanning agents, both formaldehyde and glutaraldehyde were not biodegradable and were toxic to organisms in activated sludge. Thus, they are potential inhibitors to biodegradation of other organic compounds in wastewater. However, an aliphatic aldehydic tanning agent was biodegradable and showed no toxicity to microorganisms in activated sludge. As for acrylic tanning agents, results indicated that commercial anionic products do not have any negative effect on biodegradation activity of activated sludge but they themselves were hardly biodegraded. Whereas, cationic acrylic tanning agents have the potential to inhibit the activated sludge process when presented at a high concentration. Note de contenu : - Biodegradability of aromatic syntans

Tanins végétauxIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The short-term (5 day) and long-term (30 day) biodegradation behaviours of black wattle, bayberry, valonia and chestnut tannin extracts were systematically investigated in this paper. The results indicated that all of these four vegetable tannin extracts are biodegradable although they might retard the biodegradation process to some extent owing to the inhibitory effect of tannins on the activated sludge process. Short-term biodegradabilities of the four tannin extracts were concentration-dependent. These tannin extracts could be effectively biodegraded in 5 days at concentrations of 0.25g/L, but the biodegradation process was retarded remarkably when the concentrations were increased to 5.00g/L. In general, short-term biodegradabilities of the four tannin extracts follow the sequence of valonia tannin>chestnut tannin>bayberry tannin>wattle tannin, implying that the hydrolysable tannins are easier to biodegrade than the condensed tannins. The results of long-term biodegradation showed that all of the four vegetable tannin extracts can be completely biodegraded by prolonging the activated sludge process, even if they are present at high concentration. Therefore, the encouraging findings in this research suggest that vegetable tannin extracts are environmentally friendly leather chemicals.

FormaldéhydeIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : A new simple and sensitive reverse flow injection chemiluminescence (FI-CL) method is described for the determination of formaldehyde. The method is based on the CL-Emitting reaction between ninhydrin and potassium permanganate in hydrochloric acid medium, enhanced by formaldehyde (HCHO). The calibration curve is linear in the range of 0.002 to 10µg ml-1 with r=0.9995, and the limit of detection is 4.6 x 10-4µg ml-1. The relative standard deviation for replicate measurements is 1.5 % for 4µg ml-1 of formaldehyde. The chemical and flow injection variables were studied and optimized to make the procedure suitable for determination of formaldehyde in water. It is shown that the reverse flow injection analysis could greatly improve the sensitivity and precision for determination of formaldehyde. The procedure has been applied successuflly to the determination of formaldehyde in leather wastewater, and the results were statistically compared with results determined by a standard method.
