Overall state and trend
Particulate matter emissions have been decreasing on agricultural lands in Canada, with a decline of 63% for total suspended particulate (TSP), 58% for PM10 and 61% for PM2.5 since 1981 (refer to Figure 1 below in the text box "What do the different size classes of particulate matter represent?" for an explanation of size classes). In 2011, emissions were 3,066 kilotonnes (kt) for TSP, 1,190 kt for PM10 and 276 kt for PM2.5. The greatest improvements have occurred in the Prairie Provinces and can mainly be attributed to a reduction in summerfallow, along with a shift to reduced tillage and no-till practices in this region, which has reduced the quantity of particulates produced during land preparation and harvesting.
