Wrong ranges The size ranges for pollens and several other air contaminants are wrong. Author claims that he uses http://www.engineeringtoolbox.com/particle-sizes-d_934.html as the source of the sizes. The sizes present under the link are different from those in the plot. — Preceding unsigned comment added by Mieszko the first (talk • contribs) 22:55, 06 January 2016 (UTC)

Scale

This diagram appears not to have a scale. I think it needs one. Boleslaw (talk) 16:24, 1 August 2011 (UTC)DB

I agree. The scale (micrometers) is only indicated in the description.
