“…However, it is well known that biomass combustion in domestic appliances is a significant emission source for air pollutants (Kocbach Bølling et al, 2009). Several studies were carried out in North America (e.g., Rogge et al, 1998, Purvis et al, 2000, Fine et al, 2004 andmore recently -in Europe (e.g., Boman et al, 2003, Saarikoski et al, 2008, Hellen et al, 2008, Caseiro et al, 2009.
