Low levels of manganese in welding fumes cause neurological problems | The Source | Washington University in St. Louis | Prévention du risque chimique | Scoop.it

Welders exposed to airborne manganese at estimated levels below federal occupational safety standards exhibit neurological problems similar to Parkinson’s disease, according to School of Medicine research. The more they are exposed to manganese-containing welding fumes, the faster the workers’ signs and symptoms worsen.


The findings, published Dec. 28, suggest current safety standards may not adequately protect welders.
