The aim of this study is to find the level of work related musculoskeletal disorders (WMSD) risk at work and its impact, using Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA) in Leather Garments Manufacturing Industry. Musculoskeletal Disorder (MSD) is a common health problem throughout the world and it is a major cause of disability. The economic loss due to such dis...

One of the actual global problems is an issue of waste, its formation, disposal and possible secondary processing. Another closely related issue concerns hazardous waste which represents a potential threat to environment and human health. This paper is focused on an area of waste containing hexavalent chromium arising especially from leather industry. Hexavalent chromium is classified as a carc...

The purpose of the present investigations was to improve the yield of alkaline protease for leather dehairing by subjecting the indigenous proteolytic strain Bacillus licheniformis N-2 to various mutagenic treatments viz. UV irradiations, NTG (N-methyl-N-nitro-N-nitrosoguinidine) and MMS (methyl methane sulfonate). After screening on skim milk agar plates, a total of nine positive mutants were ...

This article is focused on the calculation of heat radiation intensity and its optimization on an aluminum mould surface. The inside of the mould is sprinkled with a special powder and its outside is heated by infra heaters located above the mould surface, up to a temperature of 250°C. By this way artificial leathers in the car industry are produced (e. g. the artificial leather on a car dashbo...

Focus of this paper is the description of common used methods for hexavalent chromium measurement. This work is focused especially on commonly available spectrophotometric method based on the reaction with 1,5-diphenylcarbazide, because not every laboratory is equipped with modern devices for this pollutant measurement,. Special attention was focused on the variability possibilities of the basi...

Chromium (VI) is one of the heavy metals in water and wastewater that has the most toxic characteristic. Consequently, it is dangerous for human and environmental health. Various methods are used for removal of the chromium from wastewater, and new methods have been developed in recent years. Recent studies and investigations on the removal of environmental pollution selected methods that were ...

Chromium (III) sulfate is a popular tanning agent for producing leather. However, chrome wastewater one of the problems in leather industry. To prevent this, using vegetable materials can be used process. One natural ingredients that mimosa. mimosa relatively expensive, so substitute/combination needed to make costs cheaper. This research aims determine effect combination and silicic acid from ...

A total workforce of 5776 individuals (M=4005, F=1771, exposed n=3455 and controls n=2321) in thirty plants of the upholstered manufacturing industry in a large geographical area of Southern Italy was examined by a network of occupational health physicians over a 4-year period (2000-2003). More than 60 percent of the workforce studied was within large size companies (>500 employees). Exposed gr...

Leather industries are key contributors in the economy of many developing countries, but unfortunately they are facing serious challenges from the public and governments due to the associated environmental pollution. There is a public outcry against the industry due to the discharge of potentially toxic wastewater having alkaline pH, dark brown colour, unpleasant odour, high biological and chem...
