Vernon Dust Advisory - Ended Tuesday
The Ministry of Environment, in collaboration with the Interior Health Authority, has issued a Dust Advisory for Vernon due to high concentrations of coarse particulates, which are expected to persist until there is a change in current weather conditions.
The current advisory has been triggered by high concentrations of dust, measured as “PM10” – particles with diameter up to 10 millionth of a metre. PM10 concentrations are currently above advisory levels. Latest measurements at the Vernon Science Centre station indicate an hourly average of 75.7 micrograms per cubic metre. The average for the past 24 hours is 67.2 micrograms per cubic metre, which exceeds the provincial air quality objective of 50 micrograms per cubic metre.
The current dusty conditions are mainly caused by road traffic stirring up winter traction materials that have accumulated on roadways over the winter months.
Persons with chronic underlying medical conditions should postpone strenuous exercise until the advisory is lifted. Staying indoors and in air-conditioned spaces helps to reduce particulate exposure. Exposure is particularly a concern for infants, the elderly and those who have diabetes, and lung or heart disease.
