Is lead-based paint dust in older homes dangerous for kids?
Use caution. Lead can leach from older or imported products. Get tested if you have older plumbing.
What's actually in it
Lead is a heavy metal that has no biological role in the human body. At any dose, it damages the nervous system. Children are especially vulnerable because their developing brains absorb lead more readily than adult brains.
Common household sources include old paint (pre-1978 homes), old plumbing that leaches into tap water, some imported ceramics, and soil contamination near older homes.
