Abstract Background: Occupational Asthma is characterized by reversible airway obstruction, either spontaneously or with treatment, airway inflammation and increased airway responsiveness due to workplace exposure. It is the most common occupational lung disease in developed countries. One of causative agent is metal fume that may be encountered in steel industries. In this study we determined...
INTRODUCTION The individual and combined effect of occupational noise and vibration exposures, on workers' health has not been thoroughly investigated. In order to find better ways to prevent and manage workers' headache, this study aimed to investigate the effects of occupational noise and vibration exposure on headache/eyestrain. METHODS We used data from the fourth Korean Working Condition...
Although chronic obstructive pulmonary disease (COPD) is attributed predominantly to tobacco smoke, occupational exposures are also suspected risk factors for COPD. Estimating the proportion of COPD attributable to occupation is thus an important public health need. A randomly selected sample of 2,061 US residents aged 55-75 yrs completed telephone interviews covering respiratory health, genera...
Assessment of workplace physical exposures by self-reported questionnaires has logistical advantages in population studies, but is subject to exposure misclassification. This study measured agreement between eight self-reported and observer-rated physical exposures to the hands and wrists, and evaluated predictors of intermethod agreement. Workers (n = 341) from three occupational categories (c...
an extensive study was undertaken to investigate on the overall film badge service performance with which occupational radiation, exposures are reported in iran, the study involved the analysis of film badges exposed to x-and gamma rays and beta particles. for test exposures, x-rays between 60 and 140 kvpco-60 gamma radiation and sr-90 beta particles were used. the actual delivered dose equival...
Workers in the rubber industry are exposed to pulmonary health hazards. The main purpose of this study was to assess the combined effect of cigarette smoking and occupational exposures on lung function. The exposed group consisted of tire manufacturing workers in production units and the non-exposed group included executives from the same factory. The researchers calculated the synergy index (S...
BACKGROUND The aim of this paper is to highlight emerging data on occupational attributable risk in asthma. Despite well documented outbreaks of disease and the recognition of numerous specific causal agents, occupational exposures previously had been relegated a fairly minor role relative to other causes of adult onset asthma. In recent years there has been a growing recognition of the potenti...
PURPOSE OF REVIEW Occupational exposures in the agricultural industry are associated with numerous lung diseases, including chronic obstructive pulmonary disease, asthma, hypersensitivity pneumonitis, lung cancer, and interstitial lung diseases. Efforts are ongoing to ascertain contributing factors to these negative respiratory outcomes and improve monitoring of environmental factors leading to...
OBJECTIVE To investigate whether workplace exposures to recognized lymphohematopoietic carcinogens were possibly related to cancers in six semiconductor-manufacturing workers. METHODS A job-exposure matrix was developed for chemical and physical process agents and anticipated by-products. Potential cumulative occupational exposures of the six cases were reconstructed. The role of workplace ex...
BACKGROUND While smoking is the major cause of chronic obstructive pulmonary disease (COPD), occupational exposures to vapors, gases, dusts, and fumes (VGDF) increase COPD risk. This case-control study estimated the risk of COPD attributable to occupational exposures among construction workers. METHODS The study population included 834 cases and 1243 controls participating in a national medic...
