House Paint – Houses built before 1977 likely have lead paint, which can be inhaled or consumed through dust and paint chips.
Soil – Soil exposed to car exhaust and gasoline, particularly near busy roads, may contain lead that can be tracked into houses.
Tap Water – As water pipes corrode, lead can enter the water supply and ultimately be found in drinking or bath water.
Other – Lead exposure is also caused by specialty paints, ammunition, and items from countries that still use lead paint.
