[All] Air Quality

[Randy B. McLean]

It use to be that a API Air Pollution Index of 50 required everyone to limit the outdoors activity and that mojor polluters, ie founderies and smelters, cut back.

It is probably more complex now.

  Thanks John. The word "moderate" may be used for political reasons. We should find out what it means beyond numbers and whether the air quality index scheme is sufficient as an AQ measure -- if we can find a trustworthy expert. A Google search my help point us in the right direction.

    Last evening at the GREN meeting one of the proposals was that we request the papers throughout the watershed to publish a daily air quality index.

    The Toronto Star prints such an index with the weather every day. Today’s Toronto Star index shows that Kitchener and Guelph each have a rating today of 38 (which is considered moderate). It is important to note that this is the highest rating (i.e., worst air quality) of the cities that they reported on in the province. These included Hamilton (33), Toronto (32), and 6 other cities.
