The Long Lake wildfire in Annapolis County has broken a record in Nova Scotia for the highest number of air quality warnings and advisories, as reported by Environment Canada. Annapolis County experienced 26 consecutive days under either a warning or advisory from August 14 to September 8, doubling the previous record for the province. Although the Long Lake fire is still burning, it is now under control.
In the past, the longest stretch of special air quality statements in 2023 lasted for 13 consecutive days due to wildfires across Nova Scotia. This year saw the most destructive wildfire season in the province, scorching over 25,000 hectares of land and destroying 200 homes.
Previously, Environment Canada only issued special air quality statements, but in 2024, the agency introduced a two-tier air quality alert system across Canada. Under this system, an air quality rating between seven and 10 triggers a special air quality statement, while a rating of 10 and above results in an air quality warning.
The air quality health index assesses air quality concerning health risks, with higher numbers indicating greater health hazards.
Residents like Tanya Olscamp from Middleton describe the past few weeks as challenging, with the wildfire smoke making it uncomfortable to go outdoors and permeating homes. The smoke even triggered asthma symptoms in Olscamp, requiring her to use an inhaler.
Dr. Jean Bourbeau, a professor at McGill University specializing in respiratory illnesses, highlighted the dangerous fine particulates in wildfire smoke that can travel long distances and cause systemic inflammation when inhaled. Prolonged exposure to wildfire smoke can lead to chronic health issues, similar to those seen in smokers. Dr. Bourbeau emphasized the importance of avoiding outdoor activities during poor air quality conditions and seeking medical advice for respiratory or cardiac conditions exacerbated by smoke exposure.
Preventing wildfires is crucial for long-term health protection.
