Evidence of my scientific career and qualification to assess harmful effects of pollution with manganese (or other toxins like lead or hydrofluorosilicic acid) is available in Who's Who in America. In addition to peer reviewed publications on the harmful effects of toxins. I have given papers at the International Society of Neurotoxicology, the American Academy of Environmental Medicine, & other academic organizations. I've just returned from presenting a paper to the Midwest Political Science Association in Chicago on April 12. This paper included data on my finding that, taking into consideration other factors, pollution with manganese (as recorded in the EPA's "Toxic Release Inventory") is significantly associated with higher rates of violent crime. For all U.S. counties, where there is manganese pollution there are higher rates of violent crime. A mechanism explaining this effect is disturbance of key neurotransmitters like dopamine, which function in planning and self-control. The results matter to taxpayers. It's estimated that a year in jail costs about
2.5 million a year. The story is similar for lead or for manganese, but where both pollutants are in the same county, the effects are much worse (like mixing drinks at a cocktail party).
