Perhaps one of their biggest successes was communicating the importance of air pollution to Canadians. he Sudbury Smelter T Prior to the construction of the Superstack, the waste gases from the smelter in Sudbury contributed to severe local ecological damage. The use of open coke beds in the early to A. McMillan and G. Foley mid-20th century as well as logging for fuel resulted in a near-total loss of native vegetation. Exposed rocky outcrops were stained black, first by the pollution from the roasting yards, then by the acid rain.

Inhaled particulate from smoking is much more concentrated than that experienced from most ambient air. The dangers of smoking were established over this period and a profound cultural change has taken place to see far fewer smokers than in the past. If dose response was linear, we would expect that these changes would constitute a powerful air quality management program which would significantly reduce health impacts of particulates.
