Uh, This Raises Some Issues About Lead Poisoning, I Think

The article's about 10 years old, but I've never seen it before. Essentially, the reason that pigeons tend to have darker-colored feathers in cities is because they have more melanin in them. Why? Because it binds to heavy metals like lead and this enables them to get rid of it.

Which, of course, makes me wonder if something similar doesn't happen with humans. Does the melanin we produce help protect us from lead poisoning? How? If not? Why not?

Feathers are disposable, skin isn't.
Unless you're a snake.

Most of the dust in your house is dead skin cells, though.

Still not a super-great way for speedily getting lead out of your system though.

Humans shed the entire layer of outer skin cells about once a month.

Possibly. This is where I’m going to recognize that I’m on the Dunning-Krueger Spectrum when it comes to this topic and say I don’t know enough to even hazard a guess. Any speculation I might have is specious at best.

Great. More nightmare fuel.

The only thing wrong is the cat should be sitting on top of the roomba, judging; not getting sucked in it.
