Manganese speciation of laboratory-generated welding fumes.
The objective of this laboratory study was to identify and measure manganese (Mn) fractions in chamber-generated welding fumes (WF) and to evaluate and compare the results from a sequential extraction procedure for Mn fractions with that of an acid digestion procedure for measurement of total, elemental Mn. To prepare Mn-containing particulate matter from representative welding processes, a wel...
متن کاملDetermination of chromium speciation in fumes prepared by a plasma metal sprayer as a model of actual welding fumes.
Chromium in fumes generated in work environments including sites of welding work appears in various and complex states. Determination of chromium speciation in samples is useful for estimating the toxicity of such fumes. In the present study, determination of chromium speciation in chromium fumes prepared using a plasma metal sprayer, which are regarded as a model of actual fumes, was carried o...
متن کاملBronchial reactions to exposure to welding fumes.
OBJECTIVES To study the airway response and its mechanism to welding fumes in six welders with respiratory symptoms. METHODS Methacholine and welding challenge tests were carried out. The concentration of welding fumes during the exposure test was measured. On two subjects who developed bronchoconstricition to welding challenge, additional tests were carried out including prick, patch, and in...
متن کاملMassive hemoptysis due to welding fumes
UNLABELLED Many pulmonary problems such as lung cancer, occupational asthma, and pneumoconiosis have been described due to welding in the literature until now. This is the first case report of alveolar hemorrhage due to welding fumes presented with massive hemoptysis. We report a rare case of massive hemopthisis associated with welder's lung, with a discussion based on a review of the literatur...
متن کاملConcentration Evaluation and Health Risk Assessment of Welders' Exposure to Total Fumes and Manganese during Welding at Metal Industry
Introduction and purpose: Risk assessment of toxic or hazardous chemicals enables industrial hygienists to make appropriate decisions regarding management provisions in a healthy workplace. Exposure to total fumes and manganese during welding can have harmful effects on welders’ health. Therefore, the present study was conducted in the metal industry to evaluate the concentration and determine ...
