Autumn Leaves for US Air Quality Gradebook - Air Pollution Sources

 

Click a state on the map or list below to bring up a county index to air-pollution source sheets.  The sheets show pollutants graded C or worse for either emissions or measured concentrations.  The percentage at the end of a line is the contribution to that pollutant from the stated source.  Only the major 80% sources are listed.  The county seat follows the county name.

 

EPA references for the sources are as in the section “Emission Gradesheets.” For a description of the "tier" source categories, see “Tier Categories.”

Another summary of sources is the EPA report National Air Pollutant Emissions Trends, 1900-1998 at https://nepis.epa.gov/Exe/
ZyPDF.cgi/2000ETJA.PDF?Dockey=2000ETJA.PDF
.  Informative color plots of emissions per square mile are on pages 16 to 20 of chapter 3 of this report at https://www.epa.gov/
sites/production/files/2018-06/documents/2008report.pdf
