Occupational noise induced hearing loss in coal miners and coal washing factory workers in Kerman province
Introduction: The occupational noise induced hearing loss is one of the wide spread problems and a long term complication of working in noisy environments. At the present, large groups of workers who are working in noisy environments are exposed to hearing loss. So, this study is aimed to determine the prevalence of hearing loss (more than, 25 dB) of the workers in coal mines and leaching fac...
متن کاملvariability in fit test result for earplugs and the fraction of noise exposure dose of coal miners due to failure to wear
researchers suggested that the individual fit test be conducted to estimate the protection effectiveness of workers’ hearing protection device (hpd) while working. practically, it is convenient to conduct single, instead of multiple, fit test measurement. this study examined if a single trial of earplug fit test can represent multiple performances. additionally, it investigated how much noise e...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Lead Exposure and Oxidative Stress in Coal Miners.
We aimed to investigate the short-term correlation between blood lead levels and oxidative stress generation in coal miners. The study involved 94 male coal miners from the Velenje Coal mine, arranged into four groups: three groups according to the number of consecutive working days, and a fourth control group. Miners who worked for three consecutive days had higher blood levels of lead and 8-i...
متن کاملCoal dust exposure and mortality from ischemic heart disease among a cohort of U.S. coal miners.
BACKGROUND Particulate exposure from air pollution increases the risk of ischemic heart disease (IHD) mortality. Although coal miners are highly exposed to coal dust particulate, studies of IHD mortality risk among coal miners have had inconsistent results. Previous studies may have been biased by the healthy worker effect. METHODS We examined the dose-response relationship between cumulative...
