Arc welding produces the full spectrum of ultraviolet radiation (UVR). It is possible that welders are at greater risk of developing skin cancer than the general population, but there is a dearth of well designed studies in this area. The only major study of the relationship between arc welding and skin cancer risk did not reveal an increased incidence of skin cancer in welders. As the welders ...

BACKGROUND Welding is among the most important frequently used processes in the industry with a wide range of applications from the food industry to aerospace and from precision tools to shipbuilding. The aim of this study was to assess the level of steel industry welders' exposure to ultraviolet (UV) radiation and to investigate the health impacts of these exposures. METHODS In this case-con...

OBJECTIVES The purpose was to study the effects on the nervous system in welders exposed to aluminium and manganese. METHODS The investigation included questionnaires on symptoms, psychological methods (simple reaction time, finger tapping speed and endurance, digit span, vocabulary, tracking, symbol digit, cylinders, olfactory threshold, Luria-Nebraska motor scale), neurophysiological method...

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...

Introduction: Results from several studies indicate that workplace exposure to welding fumes is associated with increased frequency of chronic obstructive pulmonary disease (COPD) in exposed workers. Objective: To assess the prevalence and characteristics of COPD in never-smoking welders. Methods: A cross-sectional study including 53 never-smoking male welders (aged 35–60 years) was performed, ...

PURPOSE The aim of the present study was to investigate whether previous long-term exposure to manganese (Mn) via inhalation of welding fumes can cause persistent impairment in neuromotor function even long after cessation of exposure. METHODS Quantitative tests of tremor, motor speed, manual dexterity, diadochokinesis, eye-hand coordination and postural stability were administered to 17 reti...

Welding is one of the key components of numerous manufacturing industries, which has potential physical and chemical health hazards. Many components of welding fumes can potentially affect the lung function. This study investigates the effects of welding fumes on lung function and respiratory symptoms among welders of an automobile manufacturing plant in Iran. This historical cohort study asses...

Several studies suggest that welding is detrimental to the male reproductive system. Welding fume and radiant heat are of interest as possible causal factors. This study investigates semen quality and sex hormone concentrations among 17 manual metal arc alloyed steel welders with a moderate exposure to radiant heat (globe temperature ranging from 31.1 degrees to 44.8 degrees C), but without sub...

Increased volume of trapped gas (VTG), indicating small airways dysfunction, was found among 14 never smoking non-atopic welders who had worked for 10-31 (mean 22) years in their occupation. Spirometry and nitrogen wash out data were compared with those from a reference group of 14 never smoking men not exposed to welding. A methacholine provocation test was carried out. The effect was measured...

Hemeoxygenase-1 (HO-1) is a defensive enzyme against oxidative stress. Vascular epithelial growth factor (VEGF) is a potent cytokine which promotes angiogenesis. We used induced sputum (IS) technology to study HO-1 and VEGF expressions in neutrophilic inflammation in asymptomatic welders. Aircraft plant employees were divided into three groups: Welders 1 (n=30) had short-term exposure to alumin...
