Physico-chemical and toxicological characterization of welding fumes from different processes
About one million workers worldwide are engaged in welding processes, where they are exposed to a complex mixture of inhalable pollutants. Adverse effects in the respiratory system can occur due to this occupational exposure. Currently, legislative limits only exist for inhalable and alveolar particles. However, epidemiologic and toxicologic studies show that especially ultrafine particles (UFP...
متن کاملManganese 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 کاملDesigning, Constructing and Installing a Local Exhaust Ventilation System to Minimize Welders\' Exposure to Welding Fumes
Background & Aims of the Study: Welder’s exposure to welding fumes can cause occupational diseases. The current study sought to examine exposure to welding fumes among welders who work in the repair shop of Sarcheshmeh Copper Complex and design a local exhaust ventilation system to control exposure to welding fumes. Materials & Methods: This applied analytical study was co...
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...
