How does lead pollute the air? Mainly through the cars emissions that use gasoline with tetra-ethyl lead and the emissions of particulate matter resulting from the extraction, transport, manipulation and storage of lead minerals.
Starting in 1973, the federal government started a gradual phase-down of lead content in gasoline, and by 1996, banned the sale completely. However, lead from car exhausts mixed with soil near roads and is still there today. Homes near busy streets may have higher levels of lead in the soil. Today, lead still comes from metal smelting, battery manufacturing, and other factories that use lead. This lead gets into the air and then mixes with the soil near homes, especially if the home is near one of these sources.
