Nelson, Castlegar top list of worst air quality in Canada

News Today || Canada News |

The worst air quality in the nation is available by the lungful in Castlegar and Nelson, according to an international air quality technology company.

The Swiss-based IQAir (https://www.iqair.com/ca/canada) has positioned Castlegar (272) and Nelson (241) at the top of their real-time most polluted city ranking for Canada due to the degree of smoke accumulating from burning wildfires in the West Kootenay. A quality index between 201 and 300 is considered very unhealthy and a health alert.

The area between Nelson and Castlegar currently has six fires of note burning — Trozzo, Michaud, Octopus, Akokli, Cultus and Renata creek wildfires — with around 40,000 hectares in total burning.

The air quality proclamation was supported by Environment and Natural Resources Canada and prompted them to issue a smoky skies bulletin Monday morning for the Southeast Fire Centre region, noting that the area will continue to be impacted by extreme wildfire smoke over the next two days.

And for those living in the West Kootenay who have stepped outside over the last few days, in addition to smoke (and fire) they will have to contend with severe hot and dry weather for the remainder of the week, rising into the weekend.

Due to a “strengthening ridge of high pressure over the southern interior” there will be a boost to daytime high temperatures into the mid to high 30’s Celsius, with overnight lows in the mid to high teens later this week.

The hottest weather is expected to come as the week wears on, climbing to high 30’s from Wednesday to Saturday. Heat warnings may be issued for some regions as the event draws closer.

Other West Kootenay communities made IQAir’s top 10 in the nation, including Trail (189) at number four, followed by Rossland (183) at five and the Regional District of Central Kootenay (174) in seventh.

Hot times

According to Environment Canada, as the weather grows even hotter people should watch for the effects of heat illness: swelling, rash, cramps. fainting, heat exhaustion, heat stroke and the worsening of some health conditions.

“The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors,” the advisory cautioned.

People are advised to drink plenty of water before thirst sets in and, if possible, stay in a cool place.

Smoky times

Normally the West Kootenay air is clear and pure but the current smoke-infused version carries some degree of health risk.

Smoky air includes many chemicals that can harm health with a constantly-changing mixture of particles and gasses.

Some people could be adversely affected by the heavy smoke and could be challenged by symptoms such as increased coughing, throat irritation, headaches or shortness of breath.

For people who are already compromised with cardiovascular or lung disease — such as asthma — and the lungs of the very young or old, the risk is greater.
