If you live in a home built before 1978, or near a busy road, there could be lead in your house dust and soil.ften, lead poisoning is caused by lead you can't even see. Dust from lead paint is still the number one source of childhood lead poisoning. Lead poisoning can cause problems with a child's growth, behavior, and ability to learn. Lead can also harm babies before they're born.
