  • Mercury is one of the most toxic (poisonous) substances known to man and has been linked with forms of brain damage including Autism.Actually, while mercury is quite toxic, it is nowhere near as toxic as the pertussis toxin, which is 50% lethal at 429 or 546 ng per mouse, while Thiomersal is 50% lethal at 9 mg per mouse (the pertussis toxin is a million fold more lethal than mercury).
