Canadians love their hockey. With that in mind, a reasonably sized community will have an ice rink. Global Maritimes states in a news article that “there are 10 times as many rinks in Canada as there are in the United States.” That means more ice resurfacers, also known as zambonis, and ice edgers can be found in Canada than the USA.
An ice resurfacer is a machine that is used to clean and smooth the ice. An ice edger is a machine that is used at the edge of the ice rink where the ice resurfacer cannot reach. Both machineries are either powered by fuel or electricity. The exhaust produced by the fueled powered machines emits, in the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates, regardless if they are powered by gasoline, propane or diesel. These pollutants linger in the air and with inadequate ventilation; outdoor air is not brought inside to dilute the emissions from the machine(s) nor is indoor air being pushed out. So
the only way for these toxic pollutants to migrate is to be inhaled.
