Using the information in the table above, evaluate the relative risk for poor outside air quality for the following pairs of locations in terms of the pollutant sources. Which one do you think would have better air quality? Why?

i) small village vs. large city

ii) cabin in a forest with a wood-burning stove vs. farmhouse in the middle of the prairies

The Air Quality Health Index is used to inform Canadian citizens about potential health
threats related to the current conditions of the air. There are many people who are
not aware of, or have little interest in, consulting the AQHI, but as you can see in the
following table, even healthy individuals shou pay attention to these health advisories.

a) The AQHI takes into account three major pollutants: ground-level ozone (0,).
nitrogen dioxide (NO,), and fine particulate matter (which may include sulphate and
nitrate particles, elemental and organic carbon, and soil). Some sources of these
pollutants are listed in the following table.
Pollutant
Common sources
Formed when nitrogen oxides (from coal or gasoline buming)
react with volatile organic compounds (from combustion of
gasoline and wood or the evaporation of liquid fuels and solvents)
in the sunlight.
Produced by fuel combustion, mostly from transportation (cars,
trucks, and so on) and from the oil and gas industry.
ground-level ozone (0,)
nitrogen dioxide (NO,)
sulphate particles
so2 from fuel emissions is converted to sulphate in the
atmosphere.
Incomplete combustion of fuels, particularly diesel.
elemental carbon
organic carbon
Burning of biomass (for example, wood, brush) and fossil fuels.
soil
Any form of soil, but particularly in cases where agricultural activity
or deforestation has exposed soil over large areas.
