RSQA - Metal pollutants

Atmospheric concentrations of metal pollutants sampled on the island of Montreal. This program is part of the activities of the Air Quality Monitoring Network (RSQA) and improves the monitoring of the presence of [gaseous air pollutants] (. /rsqa-gas-pollutant). The set shows the metal concentration per station by sampling date. Starting in 2020, metal sampling is carried out on an annual and specific basis at stations 3, 80 and 99. Historical metal data is also available for the years 2003, 2008, 2008, 2013 and 2018 in item 3 only and for the year 2019 in items 3 and 99. Please note that the list of metals may differ from year to year.
