The Canadian Medical Association Journal, in its July 20th, 2015 editorial, titled “Adopting global guidelines for air pollution: protecting the health of Canadians” says a lot about laxity of standards that ought to aim to protect the health of the helpless. Children, carcinogenic, particles, VOCs all discussed. Pretty good read. Mirrored here.
Fave quote, “In 2008, it was estimated that more than 20,000 premature deaths related to outdoor air pollution occur each year in Canada. Yet, current Canadian standards for air pollutant levels lag behind WHO guidelines.”
