Killer smog takes toll – Ontario Medical Association

Killer smog takes toll


Smog will hasten the deaths of 348 London-Middlesex residents this year and take a toll of 9,500 province wide, the Ontario Medical Association warned today.

“It is actually a little worse than what we have found before,” said Dr. Ted Boadway, a health policy consultant with the OMA.

The London region is home to some of Canada’s dirtiest air, much of it blown in from the U.S. industrial midwest, with homegrown sources – from traffic to coal-fired electricity generation – accounting for much of the rest.

The OMA developed its estimate of premature deaths for individual areas from Environment Canada air pollution data, hospital emergency visit information and health studies during smog events.

It characterized the number as “staggering.”

Out of the 9,500 Ontario deaths, more than 1,000 are expected to occur during or immediately after periods of increased pollution.

The rest of the premature deaths are attributed to long-term exposure to air pollution.

Boadway said numbers for London-Middlesex are higher than in many areas because the region is susceptible to smog moving north across Lake Erie and northeast from the Windsor-U.S. areas.

“You can get it from two different wind directions, which makes it unfortunate,” he said.

The OMA study said rural areas aren’t exempt from smog and in some cases the air quality in the city is better than in less urbanized areas.

On high dirty air days, the OMA recommends:

-Reduce strenuous outdoor activities or confine them to early morning or evening.

-Drink fluids to stay hydrated.

-Stay in a cool, clean, air-conditioned place if you’re vulnerable to effects of smog.

-Speak to your doctor about how best to manage if you suffer from respiratory or cardiac illness.

-Know your limits and pay attention to how you’re feeling.

Boadway said there’s more public awareness about the health effects of smog than there was 10 years ago when the OMA first started studying the problem.

“When we first started to talk about this, quite frankly, it was likely speaking into an empty room. People weren’t tuned in,” he said.

“Now people are very much aware that something needs to be done about the air and the environment and they are asking their politicians to be accountable.”
