“…The contents of PAHs in the edible tissues of cephalopods have been evaluated by several authors, being squids and cuttlefish the most well characterized species (Bordajandi et al, 2004;Domingo et al, 2007;Fontcuberta et al, 2006;Gomes et al, 2013;Hwang et al, 2012;Ke et al, 2017;Martí-Cid et al, 2007, 2008Martorell et al, 2010;Moon et al, 2010;Perugini et al, 2007aPerugini et al, , 2007bRodríguez-Hernández et al, 2016;Semedo et al, 2014;Unger et al, 2008). To the best of our knowledge, limited information exists concerning the assessment of PAHs in the edible tissues of octopus; only common octopus (Octopus vulgaris) from northeast Atlantic Ocean (Semedo et al, 2014), argonauta argo from South China Sea (Ke et al, 2017), and seven-arm (Haliphron atlanticus) octopus from western Atlantic Ocean (Unger et al, 2008) were characterized. Other authors also assessed the levels of PAHs in common (Octopus vulgaris), giant Pacific( Octopus dofleini), and whiparm (Octopus variabilis) octopuses that were acquired from local fish markets and retailers not specifying the origin of species (Hwang et al, 2012;Moon et al, 2010;Rodríguez-Hernández et al, 2016).…”
