7-1 15-22 change "translocated" to "clearance" and vice-versa. Theusage of these terms is in error, and is inconsistent withusage later in the chapter.7-3 1 insert "components of" before "aerosols".7-3 14 delete "a", and insert an "s" after "parameter".7-3 16 insert "from specific sources" after "aerosols". The ambientaerosol is generally composed of multiple log-normaldistributions of aerosols from specific sources.7-3 18 change "σg" to "σg".7-3 19 change "(or 16th % particle size to the 50th % size" to "%particle size to the 50th % size, or the 50th % to the 16th %size"".7-3 20 delete "aerosol", and insert "of a specific aerosol" after "sizes".7-4 21 delete "cellular", and insert "cells of airway surfaces in the"before "ET".7-5 11 change "1 :m" to "2 :m".7-5 13 change ">0.5 :m" to ">1 :m".7-5 19 change "lower" to "smaller" and delete "largest".7-5 20 change ", which" to "that".7-5 28 change "0.3 to 0.5" to "0.2 to 1.0".7-6 4 insert ", but their length is the factor that determinesinterception deposition" after "length".7-6 6 delete "when it is electrically neutral". This is an entirelyredundant statement.7-6 9 insert "generally" before "lose".7-6 10 delete "slowly"7-6 14 insert "positive and negative" before "charges".7-6 15 change "some particles may result in an" to "particleswill result in".7-6 20 change "probably" to "often".7-7 23 insert "ET" before "deposition".7-7 30 change "0.3 to 0.5" to "0.2 to 1.0".A - 41
