This times 1000.

Lead poisoning in humans is due to lead oxides in paint and tetraethyl lead in gasoline. (modern occupational health practice was basically founded by a woman who took up the cause of lead paint workers in the 30's). https://www.acs.org/content/acs/en/e...ehamilton.html )

Mercury is pretty much only toxic when in compounds like methyl mercury https://en.wikipedia.org/wiki/Minamata_disease because it can be taken up by our cells. We don't actually metabolize elemmental lead or mercury very well. (still does' mean I'll breathe in molten lead fumes or drink elemental mercury
:-)

Toxin concentration increases up the food chain, so being on top...is bad. Hence DDT killing top predators because it gets into the algae eaten by little fish, which get eaten by the bigger fish, which get eaten by the bigger fish which get eaten by the Bald eagles.

And of us older than 26 (leaded gasoline was banned in '96) have been exposed to enough teratethyl lead to demonstrably affect our cognitive functions to some extent. https://www.nbcnews.com/health/healt...tudy-rcna19028

And yes, that includes me. It's a sobering through. Generation Lead is a real thing, and it'a not just poor kids in ghettos.
