Neurological and neurophysiological examinations of workers occupationally exposed to manganese.
The nervous system is the major target of the toxic effect of manganese (Mn) and its compounds. Nowadays, neurological diagnostics is directed towards early detection of symptoms and abortive forms, and the cases of serious damage of the nervous system are no longer reported. The aim of the present study was to assess the effects of manganese on the functions of the nervous system in workers ex...
متن کاملWelding and Exposures to Manganese Assessment of Neurological Adverse Effects
Manganese (Mn) is a required trace element for growth and reproduction with Mn deficient diets resulting in growth retardation, skeletal and joint cartilage abnormalities, fetotoxicity, testicular degeneration, diabetes and vestibular dysfunction. Mn requirements range from 30-100 ppm in the diet for various species. Man ingests 2.3-7 mg Mn/day. Calculated absorbed doses of Mn for man range fro...
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 کاملManganese and welding fume exposure and control in construction.
Overexposure to welding fume constituents, particularly manganese, is of concern in the construction industry due to the prevalence of welding and the scarcity of engineering controls. The control effectiveness of a commercially available portable local exhaust ventilation (LEV) unit was assessed. It consisted of a portable vacuum and a small bell-shaped hood connected by a flexible 2 inch (50....
