“…Sixteen EPA PAHs were considered: naphthalene (Naph), anthracene (Ant), phenanthrene (Phen), acenaphthene (Ace), acenaphthylene (Acy), fluorene (Flu), fluoranthene (Flt), pyrene (Py), chrysene (Chr), benz(a)anthracene (BaA), benzo(a)pyrene (BaP), benzo(b)fluoranthene (B(b)F), benzo(k)fluoranthene (B(k)F), dibenzo(a,h)anthracene (DB(ah)A), benzo(g,h,i)perylene (B(ghi)P), and indeno(1,2,3-c,d)pyrene (IP). After specific clean-up 41 , 42 PAHs were determined by gas chromatography coupled to mass spectrometry (GC–MS) 43 . The recovery rates, validated with spiked samples, ranged from 50% to Naph to 90% for Chr.…”
