These emissions contribute the most to adverse health effects in Minnesota.
Fine particles (PM2.5)
Nitrogen oxides (NOX)
Directly emitted from combustion sources
Volatile organic compounds (VOCs)
Data is from Minnesota’s 2011 emissions inventory. Percentages indicate the approximate amount of total emissions of pollutant of concern emitted by primary source categories in Minnesota; for simplicity, sources contributing less than 5% are not listed. Results are rounded to the nearest 5%. Emissions from wildfires, agricultural and prescribed burning are not included.
Fine particle sources shown here emit PM2.5 directly; a large amount of PM2.5 in Minnesota’s air is formed indirectly in the atmosphere from reaction of gases.
