Fig. 2 Gas chromatography-flame ionization detection chromatograms containing early artifact peaks from different solvent extraction methods Soxhlet, ASE (pie), SEE, and subcritical water extraction of a soil sample collected from a manufacturing gas plant site. The numbers refer to PAHs identified in the legend of Fig. 1. (From Ref. [12].)...
