2. Lead is toxic, but do you know why? Lead is toxic mainly because it preferentially replaces other metals in
B B B B B B B B B B B B B B B B B B
biochemical reactions. In so doing it interferes with the proteins that regulate blood pressure (which can
B B B B B B B B B B B B B B B B
cause development delays in children and high blood pressure in adults), heme production
B B B B B B B B B B B B B
(which can lead to anemia), and sperm production. Lead also displaces calcium in the
B B B B B B B B B B B B B B
reactions that transmit electrical impulses in the brain, which diminishes the ability to think and recall
B B B B B B B B B B B B B B B B B
information.
