cement dust exposure is associated with increased respiratory impairment. as the major occupational hazard in the cement production industry is cement particles, our aim was to more thoroughly examine the acute effects of occupational exposure to cement dust on the respiratory system. a cross-shift study was conducted in a cement factory in iran. 100 high exposed workers from production and pac...
background : the present study was undertaken to ascertain whether (or not) long term occupational exposure to low (sub-tlv levels) atmospheric concentrations of chlorine gas was associated with any significant decrements in the parameters of pulmonary function and/or increased prevalence of respiratory symptoms. methods : in this retrospective cohort study that was performed in 2012, 54 worke...
background: occupational exposure to excessive level of copper results in many adverse health effects. objective: to measure pulmonary function, oxidative stress, and extent of dna damage in workers of a copper processing industry. methods: 30 men working in a copper processing industry and 30 men matched for age and socioeconomic status (comparison group) were included in this study. pulmonary...
Background: Asthma is a life-threatening disease that can cause death due to bronchospasm. In addition to clinical symptoms such as wheezing, acute paroxysmal dyspnea, chronic cough after exposure to cold air or cough after exercise, spirometry is also necessary for the diagnosis of asthma. The association between respiratory symptoms and a positive methacholine challenge test (MCT) is still co...
