Air Quality Monitoring For Smart City Infrastructure ES Canada

Air Quality Monitoring For Smart City Infrastructure



Urban population (% of total population) in Canada was reported at 81.56 % in 2020, according to the World Bank collection of development indicators, compiled from officially recognized sources. The Canadian government estimate that every year in Canada, air pollution is linked to:

  • 15,300 premature deaths
  • 2.7 million asthma symptom days
  • 35 million acute respiratory symptom days
  • We estimate the socio-economic costs of the health impacts of air pollution in Canada at $120B per year (based on 2016 currency).
  • Their analysis uses the best available health and air quality data for Canada. (Source:

Hence, the expansion of cities has led to an increase in automobiles, industrial production, and rapid deforestation. Consequently, air pollution and environmental deterioration have reached an alarming stage. One of the fundamental features of smart cities is providing a sustainable environment. Rapid urbanization and industrialization have made it quintessential to monitor the environmental parameters. The major problem in environmental monitoring is real-time data acquisition through durable and accurate monitoring equipment. Hence, Compact Air Quality Monitoring Sensors play an important role in Environmental Monitoring for Smart cities.


The Quebec Association of Environmental Doctors (AQME) has raised concerns about air pollution in Quebec, stating that despite significant progress over the past two decades, air quality issues persist. Highlighting key figures, AQME reports that air pollution in Quebec is linked to 4,000 premature deaths annually with healthcare costs estimated at $30 billion. The organization emphasizes the underestimated impact of air pollution on health, listing conditions such as asthma, neurodevelopmental disorders in children, early dementia, and cardiovascular diseases among adults.

AQME advocates for the Quebec government to update the toxicity thresholds for certain air pollutants, following the World Health Organization's 2021 revised air quality guidelines. Specifically, AQME points out the dangers of fine particles (PM2.5), which due to their small size, can penetrate respiratory pathways and circulate in the bloodstream, posing significant health risks. The current daily average limit in Quebec is 30 µg/m3, double the WHO's recommended maximum of 15 µg/m3. AQME's call to action includes a push for real-time public access to pollutant levels and the establishment of a public environmental information registry to enhance transparency and inform community responses to air quality issues.

For Smart cities, it is necessary to monitor the environmental conditions for identifying the sources of pollution and mitigate them. So, a network of low-cost air quality monitoring sensor nodes can be deployed to monitor air quality and meteorological parameters. Hence, through pollution source detection, the city can take corrective measures and improve its environmental health. By installing disaster detection systems like floods and rainfall monitoring solutions in your surrounding. the citizens can be alerted beforehand
