The regional federation of municipalities says it monitors emissions of particulates, nitrogen dioxide and sulphur dioxide from Burnaby's Parkland fuel refinery, and air quality objectives for the contaminants weren't exceeded.

An extensive study of thousands of COVID-19 patients in Ontario hospitals found links between the severity of their infections and the levels of common air pollutants they experience.

In June, Birmingham, U.K., did what few other cities outside London have had the temerity to do and imposed a fee on high-polluting vehicles entering certain city zones.

The level for the most damaging tiny particles is halved, reflecting new evidence of deadly harm.

A study involving 13,000 people in London found that a relatively small increase in exposure to nitrogen dioxide led to a 32 per cent increase in the risk of needing community-based treatment.

The health burden from pollutants in the air that come from industrial activities like oil and gas extraction, mining, manufacturing, construction, and transportation — as well as natural events like forest fires — contributed to 15,300 premature Canadian deaths in 2016.

Most major Canadian cities saw drastic improvements in air quality over the last two months as COVID-19 kept people at home instead of on the roads.

Shift to gas saved more than 300m tons of planet-heating carbon dioxide as nitrogen dioxide and sulfur dioxide levels dropped

The equivalent of 11,000 new cases of childhood asthma a day occur worldwide due to toxic air from traffic, researchers say, while Canada has the third highest rate in the world, trailing only Kuwait and the United Arab Emirates. Toronto is also among the top 10 cities with the highest number of asthma cases among children.
