Figure S-1: Daily frequency of wet deposition occurrence (rain and fog) during the SONTAS 2000 in Hamilton. The frequency was determined by dividing the number of hourly counts of wet deposition during the sampling by the sampling duration (h).

Figure S-2: Hourly averaged SO2 mixing ratio at (a) Hamilton and (b) Simcoe.

Figure S-3: Time series plot of TC and molecular markers in PM10 collected at Hamilton (left) and the Simcoe (right). Error bars shown are standard errors estimated based on the replicate measurements.

Figure S-4: Plot of square root of the sum of unused eigenvalues as a function of number of loading (scree plot) for (a) Hamilton and (b) Simcoe.
