Figure 2.

Comparison of semi-quantification (triangle markers) and RIE predictive model (circle markers) methodologies (y axis) with authentic standards (x axis) for the quantification of identified compounds, shown as average concentrations (μg m^–3), within the wood burning aerosol samples. The 1:1 line is presented as a dashed line, and the 1:2 and 2:1 lines are indicated by the solid lines. Compounds within a factor of 2 from the authentic standard concentration in both methods are shown as gray markers. Compounds which do not meet this condition are presented in color.
