Dangers of Lead

 

Lead is a toxic metal that produces many adverse health effects.  Lead poisoning is a disease caused by exposure to and the absorption of lead. It is persistent and cumulative. It does not degrade. Lead poisoning is preventable.

 

Today at least 4 million households have children living in them that are being exposed to high levels of lead. There are approximately half a million U.S. children ages 1-5 with blood lead levels above 5 micrograms per deciliter (µg/dL), the reference level at which CDC recommends public health actions be initiated.

 

Protecting children from exposure to lead is important to lifelong good health. No safe blood lead level in children has been identified. Even low levels of lead in blood have been shown to affect IQ, ability to pay attention, and academic achievement. And effects of lead exposure cannot be corrected.

 

 

The goal is to prevent lead exposure to children before they are harmed. There are many ways parents can reduce a child’s exposure to lead. The most important is stopping children from coming into contact with lead. Lead hazards in a child’s environment must be identified and controlled or removed safely.

 

How are children exposed to lead?

 

Lead-based paint and lead contaminated dust are the most hazardous sources of lead for U.S. children. Lead-based paints were banned for use in housing in 1978. All houses built before 1978 are likely to contain some lead-based paint. However, it is the deterioration of this paint that causes a problem. Approximately 24 million housing units have deteriorated leaded paint and elevated levels of lead-contaminated house dust. More than 4 million of these dwellings are homes to one or more young children.

 

What can be done to prevent exposure to lead?

 

It is important to determine the construction year of the house or the dwelling where your child spends a large amount of time (e.g., grandparents or daycare). In housing built before 1978, assume that the paint has lead unless tests show otherwise.

 

  • Make sure your child does not have access to peeling paint or chewable surfaces painted with lead-based paint.

 

  • Children and pregnant women should not be present in housing built before 1978 that is undergoing renovation. They should not participate in activities that disturb old paint or in cleaning up paint debris after work is completed.

 

  • Create barriers between living/play areas and lead sources. Until environmental clean-up is completed, you should clean and isolate all sources of lead. Close and lock doors to keep children away from chipping or peeling paint on walls. You can also apply temporary barriers such as contact paper or duct tape, to cover holes in walls or to block children’s access to other sources of lead.

 

  • Regularly wash children’s hands and toys. Hands and toys can become contaminated from household dust or exterior soil. Both are known lead sources.

 

  • Regularly wet-mop floors and wet-wipe window components. Because household dust is a major source of lead, you should wet-mop floors and wet-wipe horizontal surfaces every 2-3 weeks. Windowsills and wells can contain high levels of leaded dust. They should be kept clean. If feasible, windows should be shut to prevent abrasion of painted surfaces or opened from the top sash. Take off shoes when entering the house to prevent bringing lead-contaminated soil in from outside.

 

  • Prevent children from playing in bare soil; if possible, provide them with sandboxes. Plant grass on areas of bare soil or cover the soil with grass seed, mulch, or wood chips, if possible. Until the bare soil is covered, move play areas away from bare soil and away from the sides of the house. If you have a sandbox, cover the box when not in use to prevent cats from using it as a litter box. That will help protect children from exposure to animal waste.

 

Sources of Lead

A child's environment is full of lead. Children are exposed to lead from different sources (such as paint, gasoline, solder, and consumer products) and through different pathways (such as air, food, water, dust, and soil). Although there are several exposure sources, lead-based paint is the most widespread and dangerous high-dose source of lead exposure for young children.
