Occupational asthma caused by stainless steel welding fumes: a clinical study.
The aim of the present study was to describe the cases of occupational asthma (OA) due to stainless steel welding fumes diagnosed at the Finnish Institute of Occupational Health during the period 1994-2003. OA was diagnosed according to patient history, lung function examinations and welding challenge tests with measurements of the forced expiratory volume in one second (FEV(1)) and peak expira...
متن کاملStainless steel manual metal arc welding fumes in rats.
Forty two male Wistar rats were exposed to manual metal arc (MMA) stainless steel (SS) welding fumes generated by an automatic welding device for "nose-only" exposure. The exposure simulated an actual MMA/SS welding environment as closely as possible. For the retention study, the duration of exposure was one hour per workday for one, two, three, of four weeks and for the clearance study four we...
متن کاملDissolution of stainless steel welding fumes in the rat lung: an x ray microanalytical study.
The dissolution of stainless steel welding fumes produced by manual metal arc (MMA) and metal inert gas (MIG) techniques was studied by transmission electron microscopy and quantitative x ray microanalysis in the lungs of rats after inhalation exposure. Rats exposed to stainless steel fumes generated by MMA were found to have two particle populations of different behaviour in their lung tissue....
متن کاملoccupational exposure to welding fumes using different ventilation scenarios
welders may suffer from welding fumes generated during the process if the ventilation systems are improperly applied. the objective of the present work was to study the mitigation of air pollutants at welding stations, using different ventilation scenarios. four air pollutants including iron oxide, respirable dust, ozone, and carbon monoxide were measured during four different ventilation scena...
متن کاملLung fibrosis in Sprague-Dawley rats, induced by exposure to manual metal arc-stainless steel welding fumes.
To investigate the disease process of pneumoconiosis induced by welding-fume exposure, a lung fibrosis model was established by building a stainless steel arc welding fume generation system and exposing male Sprague-Dawley rats for 90 days. The rats were exposed to welding fumes with concentrations of 57-67 mg/m3 (low dose) and 105-118 mg/m3 (high dose) total suspended particulates for 2 h per ...
