Lead is among the pollutants regularly monitored andregulated. Lead is released into the atmosphere primarily by the processing ofmetals ores containing lead and by lead-based battery manufacturing. Theeffects of too much exposure to lead include neurological damage andcardiovascular disease. Because of the Clean Air Act and its amendments,the amounts of lead in air have been decreasing for many years. The chartExbelow shows the lead concentration in air in the United States from 2000 to2016.
