AQ Reports Released

The Port recently released a report on the first quarter (Jan-Mar 2023) results of their two-year study of Strathcona air quality. Here’s a link to the first quarter report. Very briefly, this initial data found that in the first quarter of 2023, average concentrations of NO2 (which comes primarily from diesel exhaust) and PM2.5 (which comes primarily from combustion) were higher in Strathcona than other parts of Metro Vancouver, though never exceeding Ambient Air Quality Objectives (AAQO), with one exception:

 “There were some 1-hour PM2.5 concentration “spikes” observed at the 1000 Block of E Pender St. The monitor at the 1000 Block of E Pender St is located very near to the Burrard Inlet (BI) rail line. The proximity of this monitor to rail traffic may have contributed to the elevated levels of PM2.5 and NO2 recorded at this station.”

The SRA will be holding an air quality workshop when the report for the entire first year is released.

A second study was done by two UBC grad students between April and November 2022. Here’s a link to the UBC report. In summary “During the monitoring period, there were two main sources of air pollution that are easily distinguishable in our data: traffic-related air pollution (TRAP) and wildfires. Air quality also varies across the neighbourhood. Across the monitors, the highest values for nitrogen oxides occur near busy roadways and on the western portion of the study area where there is more traffic and less single-family residential housing. The opposite is true for ozone, where the highest concentrations are in the less dense residential areas. Fine particulate matter is the highest in the near-road areas and the southern residential areas of Strathcona. Throughout the study, CO levels throughout the neighbourhood are relatively consistent except for the eastern monitor on Hastings St, where they are elevated.”
