For the second year in a row British Columbia is in a state of emergency due to the number of wildfires raging in the province. Air quality across the province is being.seriously impacted.
AQHI stands for Air Quality Health Index
The 'high' (7 - 10) is the result of fine smoke particles in the air which is the PM2.5 data on the following chart. Currently Nanaimo falls in the highest 'Very High' category meaning it is 10+ on the index. In this case, a high score is not where we want to be.
The air quality objective is 25 under the category of PM25 ug/m3 and as you can see Nanaimo posted a reading of nearly 10 times that level at 5:00 am this morning with a reading of 244.0.
This is the measure of fine particles of 2.5 microns in size of which 25 in a cubic meter is considered good. At 5:00 am this morning that number was 244.0 per cubic metre.
