Protecting the Respiratory Health of Québec's Youth Population

Transportation traffic is one of the main sources of nitrogen dioxide (NO2), whether it emerges from trucks, buses, or car emissions (Government of Québec 2021). NO2 is formed from the “liberation of nitrogen contained in fuel and nitrogen contained in combustion air during combustion processes” (Government of Canada 2013). When released, NO2 has negative effects on human respiratory systems, especially those of teenagers and children (Wing, Sam E. et al 2018, 1-2). Growing evidence demonstrates that systems of asthma, for example, are likely to be aggravated or triggered in this youth segment of the population (Gillespie-Bennett, J. et al 2011, 303).
