Low levels of manganese in welding fumes cause neurological problems

(Washington University School of Medicine) Welders exposed to airborne manganese at estimated levels under federal occupational safety standards exhibit neurological problems similar to Parkinson's disease, according to new research at Washington University School of Medicine in St. Louis. Further, the more they are exposed to manganese-containing welding fumes, the faster the workers' signs and symptoms worsen. The findings suggest that current safety standards may not adequately protect welders from the dangers of the job.
