The source of the lead is Flint's water supply. Lead. But if 2005-2007 emissions data hold, up to 18 additional locations will be out of attainment with the new lead NAAQS, including communities in Alabama . Which is a major source of air pollution created by humans? Sources of Lead Exposure View Larger Text Equivalent Lead can be found throughout a child's environment. Common air pollutants with known health impacts were first regulated as "Criteria Pollutants" by the 1970 Clean Air Act which established health-based National Ambient Air Quality Standards (NAAQS). Other stationary sources include waste incinerators, utilities, and lead-acid battery manufacturers. Sources of Lead in the Air Air pollution Definition : any material is solid or liquid or gaseous are existence of air quantities lead to damage physiological and economic vitality of human beings, animals and plants .
