Lead levels in London’s atmosphere have dropped significantly since lead additives in gasoline were phased out, and currently meet UK air quality targets. The study, led by researchers from Imperial College London, found that up to 40% of lead in airborne particles today comes from the legacy of leaded gasoline.
