Lead is a highly poisonous metal that is naturally found in the
Earth's soil. Unlike other elements, lead has no benefit for
SHOULD NOT be found in the human body. Lead is a
neurotoxin, which means that it attacks the brain and nervous
system. After lead is ingested, usually through the mouth or nose,
it typically enters the blood stream and is stored in the teeth,
bones, and soft tissues of the body, such as the liver, kidneys,
and the brain.
Because it is highly durable and inexpensive, lead has been used in many products throughout history including paint, pipes, ceramics, soldering, battery casings, and gasoline. In 1978, the United States government banned the use of lead-based paint in residential buildings; however, lead is still found in many of the 875,595 Tennessee homes built before 1978. Lead-based paint is commonly found on the walls, windows, baseboards/moldings, and the outside of these homes.
