A simple blood test can detect high levels of lead. If a child is older than 1 year, consult a doctor to see if a blood test is needed. Airborne lead enters the body when an individual breathes or swallows lead particles or dust once it has settled. Lead dust is of particular concern as it is often undetected and easily absorbed. Lead dust can form when lead- based paint is dry scraped, dry sanded, or heated.
Dust also forms when painted surfaces bump or rub together.
Lead chips and dust can get on surfaces and objects that people touch. Settled lead dust can reenter the air when people vacuum, sweep, or walk through it. Wash bottles, pacifiers, toys, and stuffed animals regularly. If there is a suspicion that lead paint is present, test the home for lead. Have them wash their hands regularly to prevent them from swallowing harmful amounts of lead that may have gotten on their hands from playing in the dirt or dust.
