Overview

Air pollution is caused by substances (pollutants) that mix with air and reduce air quality, creating air that can be unhealthy to breathe. Air pollution is caused by natural sources like dust and man-made sources like motor vehicles and industrial facilities. Common household products such as aerosol sprays, paints, and solvents can also cause air pollution. In lower-income, racially diverse neighborhoods in the City’s southeast area, many homes are located close to industrial facilities and major highways and transportation corridors. The air in these neighborhoods can be more polluted because of these industrial sources and heavy traffic. These pollutants can cause serious health problems, particularly for children and the elderly.
