A road dust advisory has settled in Vernon.
The Ministry of Environment in collaboration with the Interior Health Authority has ended the advisory that was issued Monday, Feb. 3 due to elevated concentrations of dust.
“Changing meteorological conditions have improved conditions across the region,” the ministry states in a release.
The provincial air quality objective for PM10, is 50 micrograms per cubic metre (μg/m3), averaged over 24 hours. As of noon Feb. 4, the concentration was 54.8 in Vernon (compared to 74.5 Feb. 3) and 21.6 in Kelowna (compared to 18.8 Feb. 3).
“The hourly average values of PM10 in Vernon are significantly lower due to recent precipitation and the air quality continues to improve.”
The ministry, in collaboration with Interior Health, issued the advisory because of what it calls “high concentrations of coarse particulate matter,” on local roads.
Vernon is often plagued with dust advisories in the spring and this one, the first in 2020, came a few days later than the first one issued in 2019. That advisory was issued on Jan. 29.
Exposure is a particular concern for infants, the elderly and those who have diabetes and lung or heart disease.
Road dust is kicked up when traffic volumes are high and winter traction material left on dry roads.
