Air Quality Bulletin issued for Metro Vancouver and Fraser Valley

An Air Quality Bulletin has been issued for the Metro Vancouver region and the central Fraser Valley due to “intermittent high concentrations of fine particulate matter” that could occur this weekend.

In a release from Metro Vancouver, a “stagnant weather pattern over the region will bring temperature inversions and light winds, especially in the evening and overnight, causing fine particulate matter emitted by sources in our region to build up.”

Air Quality Bulletins are issued when air pollutant levels are expected to increase but don’t yet exceed levels that warrant the issuance of an Air Quality Advisory.

“Weather conditions in the fall or winter can lead to poor dispersion of air pollutants, causing emissions from local sources such as vehicles, wood stoves, fireplaces and outdoor burning to significantly impact fine particulate matter levels in neighborhoods,” said Metro Vancouver.

“Users should minimize wood burning activities and the use of fireworks until weather conditions improve.”

Residents with chronic underlying medical conditions should consider postponing strenuous exercise until the bulletin is lifted.
