Mercury's been known to be the most toxic non-radioactive element on earth for over a century yet it's still the major component of dental amalgams, although composites are more popular now for cosmetic reasons. I know the medical establishment says mercury's inert inside your teeth LOL, liability of admitting the truth would be close to a trillion dollars. It cost me around $3K to get all ten of mine removed. And ethylmercury's still used in vaccines in the states, some European countries have banned it completely.
It's used almost every industrial product that touches your skin, liquid soaps, makeup for women, toothpaste, shampoo, etc.
Most cited tests were done by the chemical companies, but I understand very few want to lose faith in billion dollar companies LOL. The real pain in the ass is learning non-toxic alternatives because you always have to read the ingredient lists.
Many people are employed by companies producing toxic stuff. Their jobs don't necessarily require them to not understand the problem, but may be a problem for those with a conscience. Personally don't believe in assigning guilt because we were all born into a society which on many levels mirrors how cancer acts.
/matrix rant off.
This is absolutely true, I know at least 300 people personally who have died of or are currently dying of mercury poisoning
