This innovative new air monitoring initiative will gather air quality data across every ward in the city.  This will be done using passive air samplers that will collect 30 day samples, 4 times per year to capture information during every season. Air pollutants to be sampled include: benzene, nitric oxide (NO), nitrogen oxides (NOx), ground level ozone (O3) and sulphur dioxide (SO2). 

The project is unique as it will not only include the deployment of many passive air monitors across the city, it is designed to include community in the process of locating the samplers, and ultimately being part of discussing and utilizing the data that emerges from the sampling process.   At least one passive air monitor will be located in every ward in the city, and additional samplers will be placed based on concerns and suggestions made by community members. Monitoring will also aim to assess whether air pollution impacts are equitably distributed across the city or whether some community members bear a heavier burden.    

The project is being led by City of Hamilton staff from the Air Quality & Climate Change  Office, in collaboration with Dr. Matthew Adams from the University of Toronto's  Department of Geography, Geomatics & Environment, and Environment Hamilton.   The initiative is being supported by Health Canada.  

This static map provides a sense of where the project's passive air monitors have been set up across the city.  Monitors have been installed in every ward - with an amplified focus on parts of the city with greater air pollution issues.
