<DIV><BR></DIV>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.

a daily air quality index.<BR><BR>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.<BR><BR>John<BR><BR>-- <BR>John
