Particulate matter is responsible for the majority of premature deaths caused by air pollution. The 63 stations in the Department of Environment and Montreal monitoring network were installed to measure the impact of road traffic, industry or wood-burning stoves on air quality.
Here are the places where concentrations are highest in Quebec.

In Montreal, the places with the highest concentrations of particulate matter are the sectors of Montreal North (Décarie and Caserne 17 stations) and East (Rivière-des-Prairies and Saint-Jean-Baptiste stations).

Several stations in Quebec have some of the highest concentrations in the province. The Vieux-Limoilou station has the highest average in the last 10 years.

methodology
Sources: Department of Environment and Combating Climate Change, data from Quebec Air Quality Monitoring Network (RSQAQ) website, City of Montreal Air Quality Monitoring Network (RSQA), World Health Organization (WHO).
The number of days of poor air quality was calculated for PM2.5, ozone (O3), carbon monoxide (CO) and nitrogen dioxide (NO2) based on Department of Health Environment and Climate Change Mitigation (MELCC) thresholds. Some stations do not calculate these pollutants and measure others for which we have not found a threshold.
For PM2.5, this is the number of days on which the three-hour mean was above 35 µg/m3 at least once a day. The annual average of PM2.5 and sulfur dioxide (SO2) was calculated by averaging the hourly concentrations recorded over the year.
For the annual mean values of the stations Lac-Édouard and Sherbrooke – Parc Cambron, daily mean values were used instead of hourly data.
The WHO standard is used on the map for stations measuring particulate matter. For sulfur dioxide, this is the Canadian standard.
