It's pretty obvious that breathing in sooty air is bad. But just how bad is it? Scary bad — as The Allegheny Front explains.
As if soot wasn't bad enough on its own, researchers are finding out it's a delivery system for super high concentrations of pollutants. Each particle acts like a magnet, collecting other toxic gases from the air and creating one super-sized poison particle that bombards your lungs with nastiness. Almost makes your chest hurt just thinking about it. [Allegheny Front via Digg]
