lead has been used in a wide variety of products including:

Where is lead found now?
Lead can still be found in lead-based paint used in older homes,
contaminated soil, household dust, drinking water pumped
through leaded pipes, lead crystal, lead-glazed pottery, airplane
fuel, some toys, and some inexpensive metal jewelry. Until 1978,
lead paint was commonly used on the interior and exterior of
homes. Deteriorated lead paint in older housing remains the
most common source of lead exposure for children in the United
States.
