Wintertime wood burning for residential heat is a large contributor to PM2.5 (particles 2.5 micrometres in diameter or less) levels in many communities (Larson et al, 2007). PM2.5 is of concern because it?s respirable and penetrates deep into the lungs (Baird, 2008). In fact PM2.5 is the air pollutant most strongly associated with increases in illness and death rates, more so than pollutant gases (Baird, 2008). PM2.5 air pollution from residential wood burning can be minimized by proper burning techniques and the use of a newer cleaner burning woodstoves. The Ministry of Environment has estimated that there are approximately 9,000 older (pre 1994) wood burning appliances in the Nanaimo area. These older appliances were not designed to minimize the amount of smoke emitted, and newer designs are greatly improved (City of Nanaimo). Provincial legislation (Environmental Management Act) specifies that these older inefficient models can no longer be sold in the wholesale or retail market in B.C.
