Manganese in Welding Fumes

New research from Washington University's School of Medicine in St. Louis suggests that welders exposed to airborne manganese at concentrations lower than current occupational health and safety standards exhibit neurological problems similar to Parkinson's disease. The results were published on December 28, 2016 in Neurology ("Dose-dependent progression of parkinsonism in manganese-exposed welders") and suggest that current occupational health and safety standards for welding fumes may be inadequate to protect welders.
