Changes in the air – Wildfire Smoke
With all of the wildfires burning from Vancouver British Columbia down to California, our air quality is some of the worst in the country. It doesn’t require the warnings from major media outlets to tell us when the air is this bad. Just look outside.
The air quality is so poor right now that DEQ suggests that all outdoor activities be very limited. You can track the biggest 5 blazes around us here: https://www.oregonlive.com/expo/news/erry-2018/08/6b8fa147951565/major-wildfires-in-oregon-blaz.html#incart_big-photo
The EPA grades the air quality from 0 to 500, with 0 being the least amount of particles in the air. Portland is currently at 176.
