Lead Hazards in Older Homes
A Big Problem
Why be concerned about lead in our
homes?
Lead has bad effects on
young children and can
cause health, behavior
and learning problems.
The placenta is
a structure which
allows materials
to diffuse from
the mother to the
developing child,
as well as in the
opposite direction.
Lead is a small molecule and can
easily diffuse to the fetus through the
placenta from the mother and have
negative consequences for the unborn
child.
Why are young children very
vulnerable?
– They tend to put objects in their
mouths.
– The body organs and the brain in
particular is still developing.
Some of these adverse effects include:
• Damage to the brain and nervous
system
