Lead-Based Paint
Exposure
Lead-based paints were used in many homes prior to its
banning by the federal government in 1978. Lead-based paints, as
the name implies, contains lead. Many documented cases of lead
poisoning can be attributed to lead contamination resulting from
the degradation of such paints. Lead-based paints in good
condition pose little risk but those that begin to peel, chip,
chalk, or crack do pose a health risk.
As lead-based paint products degrade lead can be released into
the surrounding environment in the form of dust. Lead dust can
also be formed and become airborne when lead-based paint is
sanded or scrapped. Painted surfaces when rubbed together can
also produce lead dust. The lead dust can settle and then become
airborne again when disturbed by sweeping, vacuuming, or just
walking through a contaminated area. Chips of paint flaking off
of exterior surfaces can even cause ground contamination.
Health Risks
Lead poisoning can occur when lead is ingested if inhaled and
the concentration of lead in the body will grow over time with
continued exposure. Physical symptoms of lead poisoning in
children can include: damage to the brain and nervous system,
behavior and learning problems, slowed physical development,
hearing problems, and chronic headaches. Adults are also
affected and can have: difficulties during pregnancy,
reproductive problems, high blood pressure, digestive problems,
nerve disorders, memory and concentration problems, muscle and
joint pain.
Dealing with Lead-Based Paints in Your Home
It is sometimes better to just assume that if your home was
build prior to 1980 that is contains lead based paints. (Even
though lead-based paints were banned in 1978, it is certain that
some builders and paint supplies continued to sell and use
existing stocks beyond that date). The Housing and Urban
Development department of the federal government (HUD) has a 16
page brochure giving tips on dealing with lead paint.
