The goal of this study was to examine the prevalence of chronic respiratory symptoms in potroom workers and to compare these results with changes in spirometric parameters. A modified questionnaire on respiratory symptoms from the British Medical Research Council was used to take the medical history data about respiratory symptoms. Spirometric parameters were determined on the same day (as a pa...

Certain inevitable physical factors in working environment can damage the workers in related fields. Sea sickness and white finger due to ship movement and vibration respectively are two examples in this regard. Humidity in working area can also bring discomfort of the workers in humid area. Cheese processing factories are such places where there is high humidity in the working space.Mental str...

BACKGROUND Hazardous chemicals and their metabolites may accumulate in the body following repeated airborne exposures and skin contact. AIMS To estimate the contribution of skin absorption to total body burden of N,N-dimethylformamide (DMF) across a working week in two groups with similar levels of respiratory exposure but dissimilar skin contact. METHODS Twenty five workers in a synthetic ...

BACKGROUND Exposure to wood dust can cause a variety of lung problems, including chronic airflow obstruction. METHODS Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory ratio (FEV1/FVC x 100), forced expiratory flow (FEF), forced mid expiratory flow (FMF), peak expiratory flow (PEF), and respiratory symptoms (cough, phlegm, breathlessness, wheezing, ...

background:purpose of present study was to investigate whether chronic exposure to zinc fume would affect serum zinc levels, memory, and cognition in zinc fume-exposed workers. methods:in a cross-sectional study, all zinc fume-exposed workers (exposed, n=20) were compared with unexposed workers (reference, n=20) matched for sex and education level in a zinc galvanization factory. the workers we...

anthropometry is the study of human body dimensions and proportions among different races. in work environments, poorly designed workstations and tools reduce productivity and can lead to fatigue and musculoskeletal injuries. this study aimed to determine the anthropometric characteristics of iranian workers in comparison to three other asian countries. this cross-sectional study evaluated 400 ...

A study of 2800 workers employed in three factories of the two major manufacturers of enzymatic products in the United Kingdom covering 11 years of operation from 1969 to 1980 showed that 2344 workers had sufficient lung function data to meet the operational criteria and these were analysed in three separate groups by factory locations. Spirometry and prick tests for specific skin reactions to ...

OBJECTIVES We carried out a detailed exposure assessment of benzene and toluene in two shoe factories in Tianjin, China. Our goal was to identify workers with a broad range of benzene exposures, for an epidemiologic study relating exposure to early biologic effects. METHODS A comprehensive exposure survey program was initiated. Over a period of 16 months, 2783 personal solvent exposure sample...

Introduction: Each year millions of workers throughout the world involve in occupational accidents resulting in their disability or death. The nurses, whose main task is promoting the health of the society, play an important role in preventing these kinds of accidents. Nurses are needed in industrial environment as a member of health team to prevent occupational accidents. Since most of these a...
