RSQA: Atmospheric Metal Pollutants on Montreal Island

Montreal Island atmospheric concentrations of metal pollutants sampled by the Air Quality Monitoring Network (RSQA). The dataset shows metal concentration per station by sampling date, with annual sampling at specific stations starting in 2020 and historical data for select years from 2003 to 2019. The list of metals measured likely differs from year to year.

Use Cases

• Analyze temporal trends of metal pollutants based on sampling dates from 2003 to present
• Compare metal concentrations across different monitoring stations on Montreal Island
• Assess changes in the monitored metal species based on the description noting the list may differ yearly

Strengths

• Provides historical data for specific years (2003, 2008, 2013, 2018, 2019)
• Annual sampling at stations 3, 80, and 99 established starting in 2020
• Part of a formal monitoring network (RSQA), suggesting standardized collection methods

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The list of metals measured differs from year to year, complicating longitudinal analysis
