Objectives: To investigate cardiorespiratory and inflammatory responses in male workers following exposure to welding fumes and airborne particles in actual workplace conditions. Materials and Methods: We measured blood leukocytes and their differential counts, platelet count, hemoglobin, sensitive C-reactive protein, fibrinogen, E-selectin, IL-(interleukin)1β, IL-6, IL-8, tumor necrosis factor...

BACKGROUND Workers chronically exposed to manganese in welding fumes may develop an extra-pyramidal syndrome with postural and action tremors. OBJECTIVES To determine the utility of tremor analysis in distinguishing tremors among workers exposed to welding fumes, patients with Idiopathic Parkinson's Disease (IPD) and Essential Tremor (ET). METHODS Retrospective study of recorded tremor in s...

BACKGROUND Occupational exposure to welding fumes is a serious occupational health problem all over the world. Welders are exposed to many occupational hazards; these hazards might cause some occupational diseases. The aim of the study was to assess the health related quality of life (HRQL) of electric welders in Shanghai China and explore influencing factors to HRQL of welders. METHODS 301 m...

OBJECTIVE As the findings on changes in pulmonary function of welders have been inconsistent, this study aimed to analyze respiratory symptoms and pulmonary function among welders and controls with particular emphasis on small airways dysfunction. METHODS Cross-sectional analysis, using spirometry and a standardized questionnaire, was used to evaluate 521 participants, 166 of whom (64 welders...

Workers who perform routine welding tasks are potentially exposed to fume that may contain manganese. Manganese may cause respiratory problems and is implicated in causing the occurrence of Parkinson-like symptoms. In this study, a field colorimetric method for extracting and measuring manganese in welding fume was developed. The method uses ultrasonic extraction with an acidic hydrogen peroxid...

BACKGROUND Welding process has many hazards that the welders are exposed to resulting in numbers of health effects and diseases. Safety measures and practices among welders are important ways of preventing or reducing the health hazards associated with this occupation. We conducted this study to find out the morbidity patterns among the welders working in eastern Nepal. METHODS A cross sectio...

Disruption of normal respiratory function is associated with occupational disorders. Exposure to welding fumes on long term basis affects the lung function of the workers and prompts allergic responses. Therefore, the aim of the study was to manifest the association of exposure to welding fumes and respiratory complications with reference to the undermining of normal lung function and respirato...

The Office of Naval Research has sponsored a collaborative effort between the Naval Surface Warfare Center Carderock Division, Advanced Technology and Research Corporation, Newport News Shipbuilders, the National Institute of Standards and Technology (NIST). Phase I of this effort is nearing completion to autonomously weld double-hull ship sections together. In order to accomplish the delivery ...

Background: Welding is the most common way of permanently joining metal parts. Welding, soldering, and brazing workers are often exposed to a number of hazards, including the intense light created by the arc, poisonous fumes, and very hot materials. Objective: The aim of this study was to investigate some of the health hazards among gas metal arc welders including renal and pulmonary function t...
