Generalities:

The most toxic metals are the heaviest such as lead and mercury. Currently lead poisoning is rare because this element has been eliminated from many products; however there are studies that claim that we currently have 400 times more lead in the bones than in the past. People who work in certain industries have a higher risk of contamination.

Transmission:

Fish and seafood, amalgams of mercury, industry exposure.
