Exposure to lead paint (lead-based paint), which was widely used in many homes and apartments before 1978, can damage the body's organ systems, especially the brain, nervous system, kidneys, and blood.
Small children often like to chew on objects with lead paint. When crushed or broken down, lead paint may contaminate dust and dirt in the surroundings. Children who live and play in these areas may absorb or ingest lead in harmful amounts, increasing their risk for learning disabilities, behavior disorders, slowed growth, and impaired hearing. Some toys and jewelry made in other countries have been found to contain lead paint.
In adults, lead poisoning can cause serious health problems, including high blood pressure and damage to the brain, nervous system, stomach, and kidneys.
A blood test can measure the amount of lead in the blood. This test can be done for people who are concerned about their exposure to lead or who show signs of lead poisoning.
