Wildfire smoke drifting in from central and western Canada has issued a special air quality statement for Moncton and much of northern New Brunswick.

The smoke may linger until late Saturday, affecting air quality in some regions, according to Environment Canada.

While most of it remains high in the atmosphere, some may settle closer to ground level, leading to hazy conditions and potential health risks. The sun may also take on a reddish tint due to the smoke.

Officials suggest that people more affected by air pollution, such as seniors, pregnant individuals, young children, and those already dealing with health issues, should try to spend less time outside.

They also advise anyone who notices symptoms to seek medical help right away.

Mild symptoms may include eye, nose, and throat irritation, headaches, and coughing. More serious effects, such as wheezing or chest pain, are possible but less common.

Officials are advising residents to keep windows and doors closed and use clean air filters indoors.

Along with Moncton and much of southeastern New Brunswick, the air quality statement also applies to:

• Fredericton and Southern York County
• Oromocto and Sunbury County
• Grand Lake and Queens County
• Kent County
• Kouchibouguac National Park

For those needing to go outside, authorities recommend using a properly fitted N95 mask to help reduce exposure to smoke particles, though health risks may remain.
