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.
