Yup. I had aplastic anemia as a kid. (Fixed with a bone marrow transplant.) I previously had a summer job cleaning a small PCB mfg (1983). It was fucking awful. I read that company was later fined for improper use, storage, and disposal. Can't prove cause & effect, of course. But childhood aplastic anemia is pretty rare in my area (vs agricultural areas). So it's plausible.
