Toxicology Litigation Support
Manganese is an essential element for normal body function but excess manganese in the body can disrupt neurotranmission in the brain causing a condition very similar if not identical to Parkinson's Disease. The neurotoxicity of manganese has been known since the mid 1800's as described in an elegant timeline which Dr. Parent has constructed of peer-reviewed literature publications and internal company documents. Industry chose to try to conceal the neurotoxicity of manganse in welding fumes as is described in the timeline.
