The threat of exposure to high levels of lead remains real for Americans living and working in unsafe conditions.
The Centers for Disease Control and Prevention says children living in 4 million U.S. households are being exposed to high levels of lead. Children living at or below the poverty line who live in older housing are at greatest risk.
Lead poisoning occurs when lead builds up in the body, often over a period of months or years. Research indicates about 500,000 U.S. children between the ages of 1 and 5 have blood lead levels above 5 micrograms per deciliter, the reference level at which the CDC recommends public health actions be initiated. Children under the age of 6 are especially vulnerable because their growing bodies absorb more lead than adults and because they tend to put their hands or other objects, which may be contaminated with lead dust, into their mouths.
The signs and symptoms of lead poisoning often don’t appear until dangerous amounts of lead have accumulated. Even low levels of lead in blood have been shown to affect IQ, the ability to pay attention and academic achievement. At very high levels, lead poisoning can be fatal. The effects of lead exposure cannot be corrected.
Learn Where Exposure Occurs and Minimize Risks
Lead can be found in all parts of our environment including the air, the soil, water and inside our homes. Lead has been used in a large variety of products including paint, ceramics, batteries and plumbing materials.
Typically, children are poisoned by lead-based paint and lead-contaminated dust in older buildings (built before 1978).
Adults who work with batteries, do home renovations or work in auto repair shops also may be exposed to lead. Eating or drinking from dishes or glasses that contain lead poses a risk, too.
There is no safe blood level of lead, so it is important to take steps to prevent exposure to lead. The EPA says simple steps, such as keeping your home clean and well-maintained, can go a long way in preventing lead exposure.
The EPA also recommends you:
- Inspect and maintain all painted surfaces to prevent paint deterioration
- Address water damage quickly and completely
- Keep your home clean and dust free; household dust from deteriorating lead-based paint or contaminated soil can be major sources of lead exposure for children
- Let the water run to flush the tap, use only cold water to prepare food and drinks, and use a water filter; lead in older pipes can leach into drinking water
- Teach children to keep their hands and toys out of their mouths and wash their hands frequently
