چکیده انگلیسی
Following the 2010 Gulf of Mexico oil spill, concerns were raised regarding exposure of fish to crude oil components, particularly polycyclic aromatic hydrocarbons (PAHs). This three year study examined hepatic enzymes in post-mitochondrial supernatant fractions from red snapper (Lutjanus campechanus) and gray triggerfish (Balistes capriscus) collected in the north central Gulf of Mexico between 2011 and 2014. Biomarker activities evaluated included benzo(a)pyrene hydroxylase (AHH), ethoxyresorufin O-deethylase (EROD), glutathione transferase (GST), and glutathione peroxidase (GPx). Mean EROD activity was higher in gray triggerfish (12.97 ± 7.15 pmol/min/mg protein [mean ± SD], n = 115) than red snapper (2.75 ± 1.92 pmol/min/mg protein, n = 194), p < 0.0001. In both species, EROD declined over time between 2011 and 2014. Declines in GST and GPx activities were also noted over this time period for both species. Gray triggerfish liver was fatty, and heptane extracts of the liver fat contained fluorescent substances with properties similar to known PAHs, however the origin of these PAHs is unknown.
