2.3.5 Polycyclic aromatic hydrocarbons (PAHs)
The present emission inventory for polycyclic aromatic hydrocarbons (PAH)
includes four PAHs: benzo(a)-pyrene, benzo(b)-fluoranthene, benzo(k)fluoran-thene
and indeno-(1,2,3-cd)pyrene. Benzo(b)fluoran-thene and
Benzo(a)pyrene contribute the major PAH emission by 31 % and 30 %, respectively.

series for 1990 to 2010.
The most important source of PAH emissions is combustion of wood in the
residential sector making up 88 % of the total emission in 2010. The increasing
emission trend is due to increasing combustion of wood in the residential
sector. The PAH emission from combustion in residential plants has increased
by 17 % from 1990 to 2010.
