6 Criteria Air Pollutants

+sources

What are the 6 criteria air pollutants:

1. Particulate Matter

2. Ozone (O3)

3. Carbon Monozide (CO)

4. Sulfur Dioxide (SO2)

5. Nitrongen Dioxide (NO2)

6. Lead (Pb)

Biogenic Sources

emissions that come from natural sources, non-human caused

Anthropogenic Sources

-caused by humans and their avtivities

Sources of PM 2.5

Smaller diameter:

Anthro: stationary fuel combustion/industrial + vehicles

-fires

-agriculute

-dust

Sources of PM 10

anthro: stationary fuel combustion and industrial processes

-dust

-agriculture

Sources of CO

-produced by incomplete combustion/incomplete fossil fuels

Bio: volcanoes, wildfires, and ocean

Sources of Lead

-paint 

-mobile- older cars especially relased a lot more of lead (in gasoline)

Bio: lead is hard to get rid of, so it contaminates soil, water, dust and contaminates living things. it exsists naturally in the enviorment

Sources of SO2

• COAL, fuel combustion/industrial activities (stationary sources)

Bio: fires, volcanoes, and mariene biosphere

Sources of NH3

-CAR EMISSIONS, stationary fuel combustion

Bio: breakdown of organic matter, biomass burning

Sources of Ozone:

NOx + VOC + sunlight: NOx comes mainly from motor vehicles, VOC mainly comes from industrial processes

Bio NOx: lightning 

bio: lightning
