Many manganese lawsuits are based on information that the welding rod companies (or other industries using manganese in some form) did not adequately warn people using the material of the health risks associated with inhaling or ingesting the compound.

Manganese toxicity (or manganism) can be caused by long-term exposure to any form of manganese, especially the fumes that come from welding rods. If you suffer symptoms like those of Parkinson's disease and have worked with manganese products, you may have a good case for a manganese lawsuit.

The causal link between manganese toxicity and the symptoms of Parkinson's disease -- trembling, shuffling gait, balance problems, etc. -- is quite strong, so don't let the defendant's counsel in a manganese lawsuit challenge the link. Those who work with magnesium get the symptoms of Parkinson's an average of 15 years before most people.
