[Stoves] Chart of breathable particles

[Erin Rasmussen]

I've posted this chart of breathable particles on the stoves site:
http://www.bioenergylists.org/en/content/inhalable-particles

It's a combination of some of the available data on particles small enough to inhale, and it's inspired by the available charts online. 
Please feel free to look at it skeptically, and let me know if any errors crept in.

Thanks,
Erin Rasmussen
