BACKGROUND According to official statistics, the rate of occupational accidents (OAs) and fatal injuries in Russia decreased about 5-fold and 2-fold, respectively, from 1975 to 2010, but working conditions during this period had the opposite trend; for example, the number of people who work in unfavourable and hazardous conditions (particularly since 1991) has increased significantly. METHODS...
Occupational neurotoxic diseases have become increasingly common in Taiwan due to industrialization. Over the past 40 years, Taiwan has transformed from an agricultural society to an industrial society. The most common neurotoxic diseases also changed from organophosphate poisoning to heavy metal intoxication, and then to organic solvent and semiconductor agent poisoning. The nervous system is ...
Airborne contaminants occur in the gaseous form (gases and vapours) or as aerosols. In scientific terminology, an aerosol is defined as a system of particles suspended in a gaseous medium, usually air in the context of occupational hygiene, is usually air. Aerosols may exist in the form of airborne dusts, sprays, mists, smokes and fumes. In the occupational setting, all these forms may be impor...
PURPOSE This study aims to investigate the occupational hazards among the abattoir workers associated with noncompliance to the meat processing and waste disposal laws in Terengganu State, Malaysia.

Occupational infections mostly co...
This article is a description of the current situation in France with regard to occupational cancer: research, prevention, and occupation. Toxicologic experiments are carried out using (italic)in vitro(/italic) and (italic)in vivo(/italic) tests, particularly using transgenic mice. Several epidemiologic studies have been conducted over the last decades: population-based case-control studies; mo...
Occupational exposure limits (OELs) are tools to help employers protect the health of those who may be exposed to chemicals in their workplace.

In all six studies, similar questions about the p...
Accepted 1 August 1996 Exposure limits for dangerous substances in working environments have played a major part in the control of occupational disease. Exposure limits are quantitative health standards expressed as mean concentrations over a given period which an environmental pollutant must not exceed if the exposed workers' health is not to be affected. This is true provided the term limit i...
Understanding the potential relationship between a workplace exposure and whether an employee subsequently contracts a disease represents one of the time-honoured cornerstones of occupational health research. Establishing whether a statistically significant relationship actually exists between these variables, and then quantifying it in terms of 'risk', has long been the domain of occupational ...
Urinary benzidine and conjugates have been used to assess the extent of occupational exposure to benzidine-based azo dyes. The aim of the present study was to investigate the presence of benzidine and its conjugates in the urine of workers exposed to benzidine-derived dyes. Urine samples were collected from 29 workers in three textile dyehouses, two tanneries, and two dyestuff quality control l...
