Question

ELi5: why are almost all heavy metals toxic? What do they do in the body?

In: Chemistry

Answer 1

Here 2 videos made by Chubbyemu that explain what happened to [a child who ate lead paint](https://youtu.be/5qHxEjINCAg) and [a scientist who spilled a very little amount of organic lead on her hand](https://youtu.be/NJ7M01jV058)

I’m not a scientist, nor a biologist or a medic, but I assume that heavy metals do cause problems when they “bound” with our bodies
