The half-life of lead in adult human blood has been estimated as 28 days. The body accumulates lead over a lifetime and normally releases it very slowly. Both past and current elevated exposures to lead increase patient risks for adverse health effects from lead.

Is lead toxic to touch?

Children get lead in their bodies by putting the lead-containing objects in their mouths. Touching the lead and then putting their fingers in their mouths may also poison them. Lead is more harmful to children because their brains and nervous systems are still developing.
