Ok,
now where the heck did the pollution come from???

Where did it come from? From automobiles of course. Every man's man in town has himself a diesel burning 1 ton pick up to drive back and forth to work in. Meanwhile his wife is driving a gas guzzling SUV. All that has to be done is fire up the engines and go for a drive. The result, bad air. Ask anyone in California where smog comes from. Duh.?!

The moist air takes it away, and so the dry air must create it ... ;-)

Actually, this stuff virtually all came from northeast of downtown.

In fact, the AQHI, which is different from the AQI (4 pollutants combined and short time average of 3 hours) hit around 10 on Thursday afternoon. That is the highest I have seen in the province since they started running the pilot a couple of months ago.

The SO2 readings and the NO2 readings were higher than normal at the same time that the PM2.5 was high. Had Ozone been as high as it sometimes gets, we would have seen an even higher number.

The AQI, which was dependent on the PM10 24 hour average reading the entire time, was really not that high, except that it was over 50 at all three locations at the same time for the first time this air as far as I recall.

So, the answer to the question is that it was predominately the pulp mills + Husky .... which of those was the greatest contributor, I have not got the faintest. Possibly the mills on River Road contributed some as well since the air was was quite calm much of the time.

Time to put some tracers on the emmissions and stop beating around the bush!!!

Spanky ..... actually it was all those people burning wood in their fireplaces in their virtual condos on Quebec Street.

Ya, for sure. Those virtual condo's are beautiful! My mind took a trip through one the other day. Out of this world that is for sure.
