Awareness with surveillance is important. Leaded gasoline (TEL), lead pipes, and leaded paint were a problem for IQ before the 1980's that most Americans view as "solved" today. https://www.damninteresting.com/the-ethyl-poisoned-earth https://www.damninteresting.com/the-ethyl-poisoned-earth Here's what the CDC recommends: https://www.cdc.gov/nceh/lead/prevention/sources.htm https://www.cdc.gov/nceh/lead/prevention/sources.htm

It sounds like a problem of poverty means old buildings were never decontaminated.

  It's also an issue of disrepair. Any house built in the 70s (or before) in California probably has lead paint. Which is a lot of them - that's when the primary population booms occurred. Those houses aren't being stripped of all paint, instead you need to keep the paint in good condition.

    I literally can't get my 1904 Victorian house painted with any of the modern energy saving paint on the outside because the contractors all look at the age of the house and say "that's a lead job" and then can't find a remediation contractor, plus want to charge me $100k for a paint job. But the house has been pressure washed and repainted with lead-free pain by the former owner. Has me tearing my hair, since I'm disabled and can't climb ladders to do it myself. So my house has a decaying paint job.

  It's a hard problem. Remediating lead is expensive. The standard appears that you sign an attestation that you don't know there's lead in the house. This leads to a situation where no one actually does any testing. Lead pipes and contaminated ground have their own challenges, but I was under the impression that the cheap way to remediate lead paint was to paint over it. Is that not the case, or have these places not been painted in 45 years?

    It's "screw the poor by sticking ones head in the sand." Paint chips. Kids touch the paint underneath, don't wash their hands, and then ingest toxic residue with their food.

      No, what happens is they eat the paint chips, because lead is sweet. https://www.urmc.rochester.edu/news/publications/health-matters/lead-poising-is-your-child-at-risk https://www.urmc.rochester.edu/news/publications/health-matt...

        I gave an example that didn't exclude any possibility, while you're disagreeing with a linear, all-or-nothing, black-and-white proclamation. Clearly you have an omniscient view into all child behavior. Please enlighten me as to how exactly, in specific detail, that you came about this fountain of perfect knowledge.

    If you have a window or door that inherently rubs during usage, merely painting over it won’t fully eliminate the lead dust exposure. Similarly, chipping paint (from ordinary wear) will often chip off all layers of paint. Painting over it helps, but isn’t an elimination.

Urban areas still have high lead content in the soil. The obvious one is around the foundation due to paint flecks, but also any soil near the street, due to accumulation from car exhaust.
