My results are consistent with those‚ conducted by Dr. Antonini who used the same type of welding fume particles (MMAW: manual metal arc welding). However‚ welding fume doses at 10 mg/kg and 20 mg/kg in my experiment were twice and 4 times‚ respectively‚ the dose that was used in Dr. Antonini’s paper [6]. In blood‚ Dr. Antonini found a 1.5-fold increase in Mn levels‚ whereas in my experiment I found an 8-fold increase in blood Mn after the 20 mg/kg dose. Both results are consistent since the 20 mg/kg
