The National Pollutant Release Inventory (NPRI) is Canada’s legislated, publicly accessible inventory of pollutant releases and transfers. It comprises information reported by facilities to Environment Canada under the Canadian Environmental Protection Act, 1999 (CEPA 1999), together with air pollutant emission estimates compiled for facilities not required to report and nonindustrial sources such as motor vehicles, residential heating, forest fires, and agriculture.

Using geographic information systems (GIS), we spatially interpolated average air concentrations using the inverse distance weighted (IDW) method to produce an estimated pollution surface for known carcinogens in the Aamjiwnaang region. The IDW method applies the known values at each fixed pollution monitoring site (Figure 1) to estimate levels in nearby areas. As distance from the known value increases, potential air pollution values decrease. The IDW method only provides a model of air concentrations and is an estimate. Kriging, another method of spatial interpolation, was also tested but no significant differences were found using this approach. In order to identify the major sources of pollutants, data from the National Pollutant Release Inventory (NPRI) are used to display the location of each facility and the amount of pollution released into the air (tonnes/year) for the various substances. NPRI is a publicly available database which reports the total emissions (as reported by companies) from industrial facilities on an annual basis.
