Decreasing the polarity of water by successive increase of the extraction temperature from 50 [1]C to 200 [1]C at the moderate pressure (10.3 MPa) enabled selective, non-exhaustive extractions to be performed. Concurrent with increasing temperatures to 150 [1]C there was an increase in PAH extraction efficiencies. For the majority of determinations no significant differences between extractions at 150 [1]C and 200 [1]C were observed. Varied extraction efficiencies of PAHs at the same extraction conditions reflected dissimilarities between environmental matrices investigated. S ...
