For the years 1987-1990 160 individual samples of manual metal arc stainless steel (MMA/SS) welding fumes from the breathing zone of welders in four industrial plants were collected. Concentrations of soluble and insoluble chromium (Cr) III and Cr VI compounds as well as of some other welding fume elements (Fe, Mn, Ni, F) were determined. Concentration of(More)
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(More)
BACKGROUND Studies conducted to assess aluminum (Al)-induced toxicity to humans and environment. It has been implicated that Al is involved in the etiology of Alzheimer's disease and other neurodegenerative disorders, though this is controversial. The aim of the present study was to assess Al effects on the nervous system functions in workers chronically(More)
BACKGROUND The aim of this work was to assay the concentration levels and composition of welding fumes, released during flux cored arc welding, to assess exposure of welders. MATERIALS AND METHODS Concentrations and welding fume components, such as iron, manganese, chromium (including the soluble and chromium VI), nickel, copper, calcium, aluminium,(More)
Results of evaluation of occupational exposure carried on by individual dosimetry and stationary measurements were compared. The former method yielded higher values for airborne cadmium concentrations. The investigations exhibited high cadmium oxide dust concentrations at most workplaces within the alkaline accumulator plant. Time-weighted average (per 8 h)(More)
The objective of this work was to select optimal methods for determination of toxic gases (NOx, NO2, CO, CO2, O3) and to evaluate occupational exposure of welders to those gases. The survey covered workers employed in shipyards, and other metal product fabrication plants engaged in welding mild and stainless steel by different techniques (manual metal are,(More)
A study was undertaken to assess the relationship between inhalation exposure to arsenic in copper smeltery workers and urinary excretion of total inorganic arsenic metabolites (Asitm), including inorganic arsenic (Asi), monomethylarsonic acid (MMA) and dimethylarsinic acid (DMA). The methods applied made it possible, in principle, to determine all forms of(More)
The arterial blood pressure, lipid content in serum and some organs, cadmium level in blood, aorta wall, lung and liver have been examined in rats repeatedly exposed to cadmium oxide fume 5 hours daily, 5 days a week, during 6 months. The blood pressure in rats exposed to cadmium oxide at concentration 0.02 mg Cd/m3 and 0.16 mg Cd/m3 was not changed, but it(More)
The work verifies data gathered by Occupational Hygiene departments of Sanitary-Epidemiological Stations about workers exposure to chromium compounds in the processing of chrome iron ore. Research showed that 7 plants were involved in the processing of chrome iron ore and that the number of workers directly employed in the process amounted to 215-230. About(More)
