Lead
LEAD
Lead has long
been recognized as a harmful environmental pollutant. In late 1991,
the Secretary of the Department of Health and Human Services called
lead the "number one environmental threat to the health of
children in the United States." There are many ways in which
humans are exposed to lead: through air, drinking water, food, contaminated
soil, deteriorating paint, and dust. Airborne lead enters the body
when an individual breathes or swallows lead particles or dust once
it has settled. Before it was known how harmful lead could be, it
was used in paint, gasoline, water pipes, and many other products.

Old lead-based
paint is the most significant source of lead exposure in the U.S.
today. Harmful exposures to lead can be created when lead-based
paint is improperly removed from surfaces by dry scraping, sanding,
or open-flame burning. High concentrations of airborne lead particles
in homes can also result from lead dust from outdoor sources, including
contaminated soil tracked inside, and use of lead in certain indoor
activities such as soldering and stained-glass making.
Health Effects
of Exposure to Lead
Lead affects
practically all systems within the body. At high levels it can cause
convulsions, coma, and even death. Lower levels of lead can adversely
affect the brain, central nervous system, blood cells, and kidneys.
The effects
of lead exposure on fetuses and young children can be severe. They
include delays in physical and mental development, lower IQ levels,
shortened attention spans, and increased behavioral problems. Fetuses,
infants, and children are more vulnerable to lead exposure than
adults since lead is more easily absorbed into growing bodies, and
the tissues of small children are more sensitive to the damaging
effects of lead. Children may have higher exposures since they are
more likely to get lead dust on their hands and then put their fingers
or other lead-contaminated objects into their mouths.
Get your child
tested for lead exposure. To find out where to do this, call your
doctor or local health clinic. For more information on health effects,
get a copy of the Centers for Disease Control's, Preventing Lead
Poisoning in Young Children (October 1991).
Ways to Reduce
Exposure to Lead
Keep areas where
children play as dust-free and clean as possible.
Mop floors and
wipe window ledges and chewable surfaces such as cribs with a solution
of powdered automatic dishwasher detergent in warm water. (Dishwasher
detergents are recommended because of their high content of phosphate.)
Most multi-purpose cleaners will not remove lead in ordinary dust.
Wash toys and stuffed animals regularly. Make sure that children
wash their hands before meals, nap time, and bedtime.
Reduce the risk
from lead-based paint.
Most homes built
before 1960 contain heavily leaded paint. Some homes built as recently
as 1978 may also contain lead paint. This paint could be on window
frames, walls, the outside of homes, or other surfaces. Do not burn
painted wood since it may contain lead.
Leave lead-based
paint undisturbed if it is in good condition - do not sand or burn
off paint that may contain lead.
Lead paint in
good condition is usually not a problem except in places where painted
surfaces rub against each other and create dust (for example, opening
a window).
Do not remove
lead paint yourself.
Individuals
have been poisoned by scraping or sanding lead paint because these
activities generate large amounts of lead dust. Consult your state
health or housing department for suggestions on which private laboratories
or public agencies may be able to help test your home for lead in
paint. Home test kits cannot detect small amounts of lead under
some conditions. Hire a person with special training for correcting
lead paint problems to remove lead-based paint. Occupants, especially
children and pregnant women, should leave the building until all
work is finished and clean-up is done.
For additional
information dealing with lead-based paint abatement contact the
Department of Housing and Urban Development for the following two
documents: Comprehensive and Workable Plan for the Abatement of
Lead-Based Paint in Privately Owned Housing: Report to Congress
(December 7, 1990) and Lead-Based Paint: Interim Guidelines for
Hazard Identification and Abatement in Public and Indian Housing
(September 1990).
Do not bring
lead dust into the home.
If you work
in construction, demolition, painting, with batteries, in a radiator
repair shop or lead factory, or your hobby involves lead, you may
unknowingly bring lead into your home on your hands or clothes.
You may also be tracking in lead from soil around your home. Soil
very close to homes may be contaminated from lead paint on the outside
of the building. Soil by roads and highways may be contaminated
from years of exhaust fumes from cars and trucks that used leaded
gas. Use door mats to wipe your feet before entering the home. If
you work with lead in your job or a hobby, change your clothes before
you go home and wash these clothes separately. Encourage your children
to play in sand and grassy areas instead of dirt which sticks to
fingers and toys. Try to keep your children from eating dirt, and
make sure they wash their hands when they come inside.
Find out about
lead in drinking water.
Most well and
city water does not usually contain lead. Water usually picks up
lead inside the home from household plumbing that is made with lead
materials. The only way to know if there is lead in drinking water
is to have it tested. Contact the local health department or the
water supplier to find out how to get the water tested. Send for
the EPA pamphlet, Lead and Your Drinking Water, for more information
about what you can do if you have lead in your drinking water. Call
EPA's Safe Drinking Water Hotline (800-426-4791) for more information.
Eat right.
A child who
gets enough iron and calcium will absorb less lead. Foods rich in
iron include eggs, red meats, and beans. Dairy products are high
in calcium. Do not store food or liquid in lead crystal glassware
or imported or old pottery. If you reuse old plastic bags to store
or carry food, keep the printing on the outside of the bag.
