Lead released into the environment makes its way into the air, soils, and water. Lead can remain in the environment as dust indefinitely. The lead in fuels contribute to air pollution, especially in urban areas. Soils near highways, freeways, and smelting facilities have higher levels of lead than soils in other areas because of their exposure to lead dust, which accumulates over time. Plants exposed to lead can absorb the metal dust through their leaves. Plants can also take up minimal amounts of lead from the soil.
