Detailed pollution data
Detailed pollution data, visualized below, can help clarify trends in levels of primary pollutant emissions in Canada and help explain where certain pollutants come from. These data show only pollutants emitted directly from a source, not secondary pollutants that occur from chemical reactions in the atmosphere. If linked here from another page, the default pollutant being investigated is the one that was previously being read about. If not, the default is carbon monoxide, but any pollutant can be explored. Pollutants investigated on this page include particulate matter, sulfur oxides, nitrogen oxides, volatile organic compounds, carbon monoxide, ammonia, lead, cadmium, mercury, dioxins and furans, hydrochlorobenzene, and polycyclic aromatic hydrocarbons.
Energy Source Data
The pie chart below provides some of the most basic information about the source of different pollutants. It can be used to determine the percentage of a pollutant that comes from different energy-related sources in comparison to non-energy sources.
Fuel combustion includes residential, commercial, institutional, agricultural, and construction fuel combustion.
Detailed Source Data
The bar graph below is used to expand upon the information given in the pie chart. This graph provides a more in-depth look at what activities create certain pollutants, and expands on the non-energy related sources.
Time Series Data
The line graph below is used primarily to show whether or not levels of emissions have been improving for Canada as a whole, particularly with efforts to scrub flue gases clean with various air pollution control devices. Please see Environment Canada for province by province data.
