A bit inconvenient, but from my nursing education, the studies were done and data collected from low income families (ghetto) where dwellings were in poor condition resulting in chipping paint and airborne particles not helped by single/ inattentive parents. Living conditions were the major factor, creating the problem that gave the excuse. They already knew their surveillance and control system wouldn’t work if everyone lived in a faraday cage. The WWII nurses were quite savvy, and a couple were children during The Spanish Flu. I knew vaccines were heinous before graduation, and yes, I had microbiology. The school I graduated from was #1 in the state 10 years running when I started. I went to work in a prestigious university hospital heavy into research- very educational.
That is only the beginning. Anyone who is around remodeling of buildings built before 1978 are at risk. Workers can bring lead dust from demolition activities home on there clothes and poison their own kids.
Plumbers worked with lead and even old soldering when turned into fumes is extremely dangerous. One wouldn't think an electrician would be poisoned but one was. He was trying to quit smoking and went to chewing on the wiring coating instead of chewing gum. He can no longer even work due to the result.
The worst case I ever heard of was a young mother accidently poisoning her own infant by feeding it her own breastmilk. She had been exposed and the lead had been stored in her bones (up to 30 years). Her body took the lead out believing it was iron (Fe) that the baby needed, they grow rapidly and need lots of iron; its just the lead mimics iron. So she had the lead in her own breastmilk which she fed to the baby. Insidious. As I've stated before, I can go on and on about the hazards of lead.
