Stationary combustion plants accounted <strong>for</strong> more than 93 % of the PAH<br />

emission in 2010.<br />

Table 3.12 and Figure 3.20 present the PAH emission inventories <strong>for</strong> the stationary<br />

combustion subcategories. Residential combustion is the largest<br />

emission source accounting <strong>for</strong> more than 91 % of the emission. Combustion<br />

of wood is the predominant source, accounting <strong>for</strong> more than 99 % of the<br />

PAH emission from residential plants, see Figure 3.21.<br />

Time series <strong>for</strong> PAH emissions are presented in Figure 3.22. The increasing<br />

(103 % - 148 %) emission trend <strong>for</strong> PAH is a result of the increased combustion<br />

of wood in residential plants. The time series <strong>for</strong> wood combustion in<br />

residential plants is also provided in Figure 3.22. The decrease in residential<br />

wood combustion in 2007-2009 and the increase in 2010 is reflected in the<br />

PAH emission time series.<br />
