Quebec City air quality tests are 'reassuring' but also vague about sources of pollution

Quebec City has unveiled the results of air quality testing performed in 2022 at 10 stations across the city that show pollution levels rarely exceed the daily recommended limit but fail to show exactly where the pollution is coming from.

The results found the neighbourhood ofVieux-Limoilou had the worst air quality, confirming previous findings when the neighbourhood was identified alongside Quebec City's port as having the highest atmospheric concentration of nickel in all of Canada a metal that is carcinogenic in high concentrations.

The tests, performed in industrial and residential areas between October and December last year, are part of a plan by the city, the provincial Environment Ministry and the Port of Quebec City to improve air quality in the region.

Quebec City Mayor Bruno Marchand says the results are 'reassuring' because the levels of fine particles in Limoilou exceeded the daily limit only once over a two-month period.

"No one is saying that we have reached our goal," said Marchand. "There are still things to improve."

Marchand says they have not identified the specific source causing pollution but the study identified three main elements that contributeto poor air quality in the area exhaust from nearby highways, smoke from wood stoves and fireplaces and emissions from industrial activities.

Action plan a 'first' for the city

Raymond Poirer, president of a citizens' committee representing Vieux-Limoilou, doesn't find the results all that reassuring,saying"one time over the norm is one time too many."

He says thefindings are similar to those shared over the past year by the city.

What is new, he says, is how the city is proposing to move forward announcing an action plan with seven priorities tofocus on over a five-year period.

"For the last 10 years, the citizens here have been mobilized. For the last few years there have been concrete actions that have been done by citizens and now we see the city of Quebeccoming with a plan, a vision and that's something concrete," said Poirer.

"That's a first."

Some of the measures include acquiring electric garbage trucks and buses to reduce emissions, regulatingwood stoves and hosing down the tires on trucks in industrial areas to reduce the amount of dust being moved around.

Poirer, who started a citizen-led scientific program called Limoilair to monitoremissions,says this action plan will only work if partners step up to follow the city's lead.

"There's a lot of talk but not a lot of action," said Poirer.

"They actually need to do the hard things and not necessarily the easy things."

A 'new era of collaboration'

To complement this plan, Port of Quebec CEO Mario Girard saidTuesday they have introduced their own measures to reduce nickel contamination. Among them, is supporting Glencore's new technologies to safelyload nickel from Northern Quebec onto ships at the port.

"The norm has been respected for the past year. There has been no exceeding of the norm, but we're not stopping there," said Girard.

"We have a lot of technologies we're looking at."

Quebec Environment Minister Benoit Charette says this partnership is creating"new era of collaboration."

"We made a commitment to be as transparent as possible, one, to show our interest in this file which is a priority for us but to also build trust," said Charette.

Still, Limoilou resident Mara Beaudry has many questions about how other industries will be regulated to mitigate pollutants.

"I think it's still very vague and we're here on the ground continuing to live the effects of the poor air quality," said Beaudry.

Since moving to the neighbourhood 12 years ago, she has been dealing with thick grey dust on her patio and windows and worries about the impact of the air quality on her children's health.

"I don't have the impression that this action plan that was presented will allow for any changes in the short term for us families in Limoilou," said Beaudry.
