The purpose of the study was the evaluation of electromagnetic field (electric field strength of 20V/m, f=50Hz and magnetic field strength of 2A/m, f=50Hz) effects on the antioxydative activity in steelworkers' red blood cells and plasma. The plasma GSH-Px (EC 1.11.1.9) activity, MDA and ceruloplasmin levels as well as SOD (EC 1.15.1.1.), CAT (EC 1.11.1.6) and GSH-Px (EC 1.11.1.9) in red blood cells were measured. Statistically significant decreases in red blood cells SOD and GSH-Px activities, a CAT activity increase and plasma MDA increase and a ceruloplasmin decrease were found in workers exposed for 3-10yr and for longer than 10yr to electromagnetic fields. No statistically significant changes in the parameters evaluated were found among steelworkers employed for shorter than 3yr. All changes observed among workers exposed to electromagnetic fields result in adaptative responses by activating systems controlling the balance of body oxidative mechanisms.
