@fullsquare@awful.systems Lead poisoning was *ubiquitous* in the USA until the late 1970s/early 1980s, due to tetraethyl lead in petrol. Everywhere around the world experienced a sharp drop in violent crime 15-20 years after it was phased out. But mercury poisoning is more visibly lethal: see also Karen Wetterhahn: https://en.wikipedia.org/wiki/Karen_Wetterhahn

i’m aware, last year i’ve been tasked to use a certain process but refused and instead modified it in such a way as to get rid of mercury salt used; it was dissolved in DMF, so (regular nitrile) gloves won’t even help. worse than that, it took me only 2-3 weeks start to finish to figure it out, meaning that anyone else could do that earlier and handful of people were put at risk for no reason. aggression as a result of lead toxicity is probably a bit more complex story and looks like it might have a developmental part, judging by delay and how kids are more susceptible to lead toxicity in general; meaning that presumably mostly adults won’t be affected to the same degree. another big nope on my list would be thallium and cadmium compounds, and while i’d only use sub-g amount at most, there are places where all of these metals are mined, and at one point are in form of fine dust
