[Stoves] Chart of breathable particles

[Peter DeCarlo]

Hi All,

I think there is good utility in putting together this information however,
I'm a little confused by the data in the chart.   I think there may be some
unit issues.  Where exactly did the data come from?  I couldn't find it in
the papers listed at the bottom of the chart. For example human hair in the
chart is on the scale of a micron, when it should be more like hundreds of
microns a millimeter or so.  Similarly smog size range is more from 10s of
nanometers (0.01 microns) to 1 micron, but is smaller than that in the
graphic (several other ones too). I don't want to be too nit-picky here, but
the information just doesn't seem quite right.

In response to the question of whether we can separate out BC and OC in the
size chart, I'm not sure that's really advisable since the BC and OC are
nearly always a mixture, implying it isn't really physically meaningful to
have different sizes for the each component if they are part of the same
particle.

Just my 2 cents.
