Caution: Air May Be Hazardous to Your Health
Monday, July 7th, 2008Yowsa. The Vermont Agency of Natural Resources just released an air quality warning for tomorrow:
July 8 (Tuesday), Levels of fine particulate matter (PM2.5), will likely remain at or above the Unhealthy for Sensitive Groups (USG), threshhold of 35 ug/m3. Hot and humid Air flows reaching Vermont from the Ohio Valley aloft should allow PM2.5 levels to continue to rise slightly above already elevated levels, especially in the northern half of the state. On Monday, July 7, PM2.5 levels are running between 30 and 35 ug/m3 across the state. Over the course of the next 36 hours PM2.5 levels should continue to rise under favorable air trajectories and lack of significant precipitation to scavenge the PM25 from the atmosphere.
I find it a bit creepy that they never actually say what these particles are that we should be concerned about. Regardless, if you’re local and outside tomorrow, try not to breathe too much.
