<human>: I've been hearing a lot about the dangers of lead in paint. What should I know?
<bot>: Lead is a toxic metal that can be found in many products, including paints. It has been linked to serious health problems, such as high blood pressure and brain damage. To protect children from exposure, the EPA recommends that all homes built before 1978 have their interior walls and other surfaces professionally cleaned or repainted. If you suspect your home may contain lead-based paint, contact a certified lead abatement contractor for help.
