original article   thermal stress is a well-recognized health hazard in the workplace. in addition to the health deficits, working in the heat can affect significantly on the productivity of some industries located in rough environments. the current indices used to evaluate the environment are either flawed or difficult to implement. the focus of this review is upon heat stress indices used in ...

Cardiovascular effects of potential occupational hazards have received relatively little attention. The major inhalant occupational exposures of concern are carbon disulfide, nitrates, halogenated hydrocarbons and carbon dioxide. Occupational exposure to certain trace metals may also be associated with adverse cardiovascular effects. Of concern is potential toxicity from cobalt, antimony, lead,...

The WBGT heat stress index has been well tested under a variety of climatic conditions and quantitative links have been established between WBGT and the work-rest cycles needed to prevent heat stress effects at the workplace. While there are more specific methods based on individual physiological measurements to determine heat strain in an individual worker, the WBGT index is used in internatio...

background: noise is one of the most pervasive hazards in industrial settings. this retrospective study was carried out to assess the effects of noise exposure on hearing status, blood lipids and blood pressure of employees of a local fireclay mine. methods: two hundred and forty male workers were studied. data on audiometric measurements, blood lipids and blood pressure were derived from the w...

background: occupational lead poisoning is common in workers of some industries, but lead hepatotoxicity has rarely been reported. several animal studies have revealed lead induced liver damage but clinical studies concerning the manifestations of lead induced liver toxicity in humans are scares. this study was designed to investigate the clinical manifestations and pathological parameters of h...

noise-induced hearing loss, which is one of the 10 leading occupational diseases, is a debilitating and irreversible disease. during the recent 15-years period (1997-2012), several studies have investigated the association between noise, hearing damage and other side effects of noise in iran. the aim of this study was to review systematically the relevant literature related to noise-induced hea...

background: with the fast growth in the market of fluorescent lamps, particularly compact fluorescent light, the associated risk of mercury exposure, which is an essential component in all types of fluorescent lamps, has received increasing public attention worldwide. even low doses of mercury are toxic. objective: to study the health consequences of occupational exposure to mercury in workers ...

background: respiratory problem is one of the major health hazards in dust-exposed workers; it is a major cause of morbidity and mortality all over the world. objective: to determine the prevalence of respiratory problems and lung function impairment among quarry workers in ebonyi state, nigeria. methods: respiratory problems and lung function were studied in 403 quarry workers aged 10–60 years...
