a Fine particulate matter less than 10 microns. Data include PM without condensable.

b Industrial processes consists of chemical and allied product manufacturing, metals processing, petroleum and related industries, other industrial processes; solvent utilization; and storage and transport.

c In 1985 there appears to be a spike in Miscellaneous emissions. This is likely due to a methodological change, and the EPA does not change historical data when it changes its methodology.
