Residential Wood Burning: A Major Source of Fine Particulate Matter in Alpine Valleys in Central Europe - Urban Air Quality in Europe - page 130

Fig. 1 Map of sites in the Alpine region where results on the contribution of wood burning
emissions to PM, OC and EC have been reported

PM10, OC and EC at the Northern Italian sites in Milan, Sondrio and Cant ` as
reported by Piazzalunga et al. [ 52 ].

3.2 Impact of Wood Burning Emissions on Air Quality

Table 1 summarises the results of 18 publications on the impact of wood burning
emissions on PM, OC and EC at sites in the Alpine region, denoted here as PM wb ,
OC wb and EC wb , respectively. The table provides (subject to data availability)
absolute contributions from wood burning emissions at 27 measurement sites.
In addition relative contributions from wood burning emissions to total EC, OC
and PM are presented together with the concentrations of wood combustion tracers
levoglucosan and water-soluble potassium as well as the ratio of levoglucosan and
mannosan. For all sampling stations, the site type, the PM size-cut, the measure-
ment season and references are also listed. The applied source apportionment
approach is given, further details can be found in the corresponding publications
as well as in Sect. 2.3 . Some sites appeared repeatedly in different studies with
different sampling periods. These stations appear in Table 1 repeatedly.
