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 shows 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 jumbo-sized poison particle that bombards your lungs with nastiness. Almost makes your chest hurt just thinking about it. [Allegheny Front via Digg]
