Effects of Electromagnetic Field on Free-Radical Processes in Steelworkers. Part II：Magnetic Field Influence on Vitamin A, E and Selenium Concentrations in Plasma

The aim of the study was the evaluation of the influence of electromagnetic fields (electric field strength of 20 V/m, f=50 Hz and magnetic field strength of 2 A/m, f=50 Hz) on the concentrations of vitamin A, vitamin E (α- and γ-tocopherol), and selenium, which represent non-enzymatic antioxidants,...

Description
Summary:The aim of the study was the evaluation of the influence of electromagnetic fields (electric field strength of 20 V/m, f=50 Hz and magnetic field strength of 2 A/m, f=50 Hz) on the concentrations of vitamin A, vitamin E (α- and γ-tocopherol), and selenium, which represent non-enzymatic antioxidants, in the plasma of steelworkers exposed to such a field. The cohort was divided into 3 study groups： group 1 , workers employed for less than 3 yr； group 2, employed for 3-1O yr； and group 3, employed for more than 1O years. Analysis of the results obtained revealed a statistically significant decrease in plasma vitamin A, α-, and γ- tocopherol concentrations in the study groups as well as a marked increase in plasma selenium concentrations in groups 2 and 3. These changes suggest that the electromagnetic fields studied cause an increase in free-radical process activity in steelworkers .
