Air quality in Calgary deteriorates due to wildfire smoke

Wildfire smoke from B.C. and California has deteriorated the air quality in Calgary,and those with pre-existing lung and heart conditionsmay want to keep inside until the haze lessens.

Environment Canada bumped the city's air quality health index on Thursday to a four,which is considered a moderate risk for people withrespiratory and cardiovascular issues.

They should consider reducing strenuous activity outdoors, and monitor for symptoms of discomfort.

Though the general population shouldn't have to rescheduletheir outdoor activities, they should be mindful of coughing or throat irritation, and head inside if these symptoms occur, according to the advisory.

On Twitter, Environment Canada meteorologists warned that the haze could get worse in Calgary next week, asthe weather pattern carrying the smoke continues.

Depending on the direction of the winds, meteorologists said the smoke could also increase inEdmonton, but it is difficult to forecast at this stage.

Edmonton currently sits at anair quality health index of three, or low-risk, butis no stranger to wildfire smoke.

In August2018, it earned thedistinction of havingthe worst air quality in the worldafter smoke and haze drifted in from B.C. and blanketed the city.
