Wildfires – Siberia
Wildfires in Russia’s Far East and Siberia swelled by 3,600 ha to 16,700 ha over the past 24 hours, the Russian Aerial Forest Protection Service reported on Friday.
“The major increase occurred in the Magadan Region – in one day the wildfire area grew 43-fold from 40 ha to 1,700 ha. In the Amur Region the wildfires grew from 1,700 to almost 2,000 ha, and in the Irkutsk Region – from 4,000 to 5,200 ha,” the service said.
Wildfires – New Mexico, USA
Eleven wildfires are burning in New Mexico as of Thursday. The state Department of Health issued a smoke advisory for northern parts of the state.
Air Pollution From Wildfires Much Worse Than Previous Estimates
Particle pollution from wildfires, long known for containing soot and other fine particles known to be dangerous to human health, is much worse than previously thought, a new study shows.
Naturally burning timber and brush from wildfires release dangerous particles into the air at a rate three times as high as levels known by the EPA, researchers at Georgia Tech found.
Scientists sampled air quality by flying planes directly into thick plumes from three major wildfires, including the 2013 Rim Fire, the largest wildfire in the Sierra Nevada. Previous EPA data was based on plume samples from controlled burns. Greg Huey is the study’s lead author.
“Under the conditions of the prescribed fires, it seems like you can get a smaller impact on air quality, So I think an extrapolation is that if you had more prescribed burning you might prevent some wildfires and in the process of doing that you would also probably help air quality issues,” Huey says.
The study also found wildfires spew methanol, benzene, ozone and other noxious chemicals.
