Ground-level ozone leads to air quality statements for Metro Vancouver and Fraser Valley
“Metro Vancouver is now issuing an air quality advisory for eastern parts of Metro Vancouver and the Fraser Valley because of high concentrations of ground-level ozone that are expected to persist through the week,” Environment Canada said, in a statement.According to Metro Vancouver Regional Districts’ airmap, the affected communities include: New Westminster, Coquitlam, Pitt Meadows, Maple Ridge, Surrey, Langley, Abbotsford, Mission, Chilliwack and Hope.
“Ground-level ozone is not emitted directly into the air but is formed when nitrogen oxides and volatile organic compounds react in the air in the presence of sunlight,” Metro Vancouver Regional District said, in a release.The ongoing Nohomin Creek wildfire, burning near Lytton, B.C., is contributing to the hazy conditions seen around the region. However, the wildfire has not had a significant impact on the measuring fine particulate matter on the ground level, according to Environment Canada.
