Figure 1s: Flow diagram of experiments to evaluate accuracy: Comparison of results among agitation (AG-D and AG-DM using dichloromethane and dichloromethane/methanol, respectively), microwave (MAE) and Pressurized liquid (PLE) extractions. Sampling date and mass loadings of collected particulate matter (mg) are included in parentheses.

Figure 2s: Flow diagram of experiments to evaluate intermediate precision: Comparison of results of agitation (AG) with microwave (MAE) and Pressurized liquid (PLE) extractions.

Table 2s: Results obtained from the analyses of the reference material, SRM 1649b, using agitation/sonication procedure and dichloromethane as extraction solvent. Results are expressed in µg g1 and ng g1 for PAHs and NPyr, respectively.

Table 3s: Calculations of intermediate precision as Percentage difference by estimating a relative standard deviations of the normalized differences: The normalized difference data was calculated as the difference divided by mean value for each pair of data.
