aTSP = total suspended particulate matter aerosols
with aerodynamic diameter <75 µm
bPM10 = suspended particulate matter
aerosols with aerodynamic diameter <10 µm
cPM2.5 = suspended particulate
matter aerosols with aerodynamic diameter <2.5 µm
dN = number of samples above detection limit
that were included in calculations
eRPD = relative percent difference where an
RPD of 100% corresponds to a difference between values of a factor of 3.
