Wood smoke and heating fuels in Canada

Wood smoke and heating fuels in Canada

From the data charts, I drew pie graphs which represent the air contaminants present in Canadian residential
neighborhoods. The data show only the pollution originating from home and commercial heating fuels, and does
not include pollution from vehicles driving within these areas. If vehicular pollution were factored in, the PM2.5,
CO, and VOCs originating from the wood smoke would have amounted to slightly lower percentages of the total.

But a car is a moving source, whereas a home chimney is a stationary source. So during any given instantaneous
time interval, there would be a significantly higher probability that these pollutants originate from the stationary
point sources. (chimneys in private homes)

The homes with electric heat were accounted for not as having zero emissions, rather, the (usually) distant
coal-fired electric plant emissions were considered. If this is the case, most of the NOx, and almost all of the
SO2 values, can be ignored as they were not be present in the immediate vicinity of the homes present. (that is,
unless the facility was located nearby, or actually in, a neighborhood)
