Ranges of percentage change in annual inhalation dose with a standard deviation change in selected parameters with their baseline values and standard deviations: top five most sensitive parameters for either urban or rural sub-population.

aOutdoor concentration of some other PAH congeners could also bring percentage change of over 1% but were omitted for clarity, which included BaP, Nap, DBA, BbF, BkF, Acy in all seasons, and IP, Ant, BaA, Phe, Flu in winter. They all had smaller percentage influence than BaP in winter.bQuantity of coal used could also bring percentage change of over 1% but was omitted for clarity. It had smaller percentage influence than the quantity of wood and crop residues used.cSD stands for standard deviation, which is listed in brackets.dValues separated by “/” are percentage changes when subtracting or adding standard deviations to the baseline values.eRankings of variables for urban and rural sub-populations respectively are listed in brackets; the table is sorted by the larger of the percentage changes in annual inhalation dose for urban and rural sub-populations.
