The monosaccharides fructose and glucose showed median concentrations of 27 ng m3 and 33 ng m3 in 2012 and of
23 ng m3 and 31 ng m3 in 2013, representing 0.17% and 0.21% of the OC in 2012 and 0.084% and 0.12% of the OC in 2013. A straightforward explanation for the higher contributions in 2012 could not be found. The polyols arabitol and mannitol exhibited median concentrations of 9.3 ng m3 and 11.3 ng m3 in 2012 and of 11.6 ng m3 and 14.8 ng m3 in 2013, corresponding to 0.061% and 0.070% of the OC in 2012 and to 0.044% and 0.053% in 2013. The arabitol and mannitol concentrations may be compared with those reported in a previous study for PM10 samples from two sites in
Vienna, Austria, where the concentrations were estimated at 22 ng m3 and 34 ng m3 in 2004 for an urban fringe site and at 28 ng m3 and 42 ng m3 in 2005 for an urban traffic site (Bauer et al., 2008).
