Evaluate workplace air, dust and its effect on pulmonary function of workers in a modern cement factory

Ergonomics is a multidisciplinary knowledge of the various issues in the workplace Zzvayay looks different. One of the major topics in health issues is considered ergonomics and its role in labor productivity and help organizations to accelerate sustainable development. Definitely affect the health workforce special conditions governing his work and also has the effect of ergonomic factors. B-factors of the total chemical agents at work and consequently the exposure factor and pollution emissions resulting from business processes the workplace and environment that this kind of pollution emission and waste energy in fact, some ergonomic design appropriate processes and lack of coordination between these factors need to control the dust on the gas, which leads to Shrat that it is Some form of energy to gain release of pollutants in the workplace and the workforce in the health Mvachhh threaten to cast him. Therefore, based on the view factory workers with exposure to pollutants, dust emissions from cement production processes are studied for the purpose of this study was to evaluate comparative Total dust and respirable silica and determination of free and total chromium Drkakhanh cement and its effects on the respiratory system are the workers. Methods of environmental sampling and personal contact with dust and respirable and total expressions were measured. Dust concentration measuring method, weight was determined. IR-Spectrophotometry (ICP-Atomic Emission Spectroscopy) The dust samples taken to determine the amount of free silica and total chromium by techniques IR-Spectrophotometry and atomic emissions spectrometer (ICP-Atomic Emission Spectroscopy) and were read and analyzed. Results showed that mean concentrations of respirable dust and total (except for respirable dust concentration into peripheral milling of raw materials) of free silica concentration in respirable dust and total chromium in respirable dust samples than Bulk is the limit. T test between mean pulmonary capacities of workers with group control group there was no significant difference. (P<0.05) mean lung capacity than non-smokers among workers Sykary Mvrdkahsh groups indicated. (P<0.05)/ The statistical analysis of the distribution of work and square, Fisher test showed that the frequency of symptoms of respiratory distress (cough - sputum out of the chest, shortness of breath) among groups of workers with the control group there was a significant difference (P
