Aerosol Size Distributions The following questions refer to the aerosol size distribution in the table below, adapted from "Atmospheric Chemistry and Physics" by Seinfeld and Pandis (Chapter 8) Size Interval (aerosol Mean of Size Interval (aerosol diameter, um) Number of Particles in Interval (cm³) diameter, um) 0-.2 .1 10 2-.4 .3 80 .4-.6 .5 132 .6-.8 .7 142 .8-1.0 .9 138 1.0-1.2 1.1 112 1.2-1.4 1.3 75 1.4-1.6 1.5 65 1.6-1.8 1.7 52 1.8-2.1 1.95 65 2.1-2.7 2.4 50 2.7-3.6 3.15 35 3.6-5.1 4.35 40 3) Plot the normalized (divided by the width of the size interval) number-size distribution of the described aerosol population. 4) Plot the normalized surface area distribution of the described aerosol population. Assumptions: all aerosols are spherical; you may assume that all species in a given size bin have the mean diameter. 5) Plot the normalized volume distribution of the described aerosol population Assumptions: all aerosols are spherical; you may assume that all species in a given size bin have the mean diameter. 6) Which aerosol size interval(s) are likely to be most important for aerosol health effects? Explain why.
