“…In this study, total (Σ) APAH in bivalves were ca 2 to 10 times greater than ΣPAHs concentration although ΣAPAHs were 1.2 to 4.5 times lower in sediments at each sampling site. A similar trend was reported for vertebrates and invertebrates from the Northern Gulf of Mexico after the Deep Water Horizon (DWH) oil spill and Dubai Star Bunker fuel oil spill in San Francisco Bay . An increase in APAHs relative to parent PAHs was also observed in benthic invertebrates from the North Chukchi Sea …”

“…A similar trend was reported for vertebrates and invertebrates from the Northern Gulf of Mexico after the Deep Water Horizon (DWH) oil spill and Dubai Star Bunker fuel oil spill in San Francisco Bay. [15][16][17] An increase in APAHs relative to parent PAHs was also observed in benthic invertebrates from the North Chukchi Sea. 18 Although the unsubstituted PAHs have received more attention, evidence is mounting that the alkylated congeners are more inherently toxic than their parent analogs.…”

“…These species were exposed to the individual compound phenanthrene via environmental or experimental exposures (i.e., dietary, intragastric, or intraperitoneal). In addition, Kemp's ridley sea turtles collected in the northern Gulf of Mexico during the Deepwater Horizon spill had detectable levels of 1-, 2-, and 3hydroxyphenanthrene, albeit at generally low concentrations ( 35 ng/g wet wt) [38]. Thus, these studies, combined with the results from the present study, suggest that 1-hydroxyphenanthrene may be the principle biotransformation product regardless of species, exposure route or whether phenanthrene is introduced as a single compound or within a complex mixture such as crude oil.…”

The 2 most abundant polycyclic aromatic hydrocarbons (PAHs) measured in Deepwater Horizon crude oil, naphthalene and phenanthrene, and their associated homologs have both been shown to be acutely toxic in fish. Although fish have a relatively high metabolic capacity for PAHs, hydroxylated PAH (OH-PAH) derivatives formed during the initial metabolic response can negatively impact the health of fish. Species-specific metabolism of naphthalene and phenanthrene was evaluated in 3 marine teleosts, red drum (Scianops ocellatus), Florida pompano (Trachinotus carolinus), and southern flounder (Paralichthys lethostigma). Fish were exposed to Deepwater Horizon crude oil by intraperitoneal injections at time 0 and 48 h, with bile sampling events at 24 and 72 h post injection. The data suggested metabolic induction in Florida pompano and red drum, whereas southern flounder may have demonstrated metabolic fatigue. By 24 h post injection, overall profiles of red drum and southern flounder were dominated by hydroxylated phenanthrene metabolites; conversely, the Florida pompano profiles were dominated by monohydroxylated naphthalenes. In addition, Florida pompano had faster overall relative biotransformation rates, suggesting their potential decreased susceptibility to adverse effects. Red drum and southern flounder had much lower relative biotransformation rates, indicating their probable susceptibility to adverse outcomes after naphthalene and phenanthrene exposures. To our knowledge, the present study is the first to investigate monohydroxylated PAHs in fish exposed to Deepwater Horizon oil.

“…Dead, sick, or injured turtles found washed up on the coast can provide valuable information on their health status, and point to the primary causes of morbidity and mortality in a zone or region. Threats identified in stranded sea turtles include interactions with fishing gear (Monteiro et al, ; Tomás, Gozalbes, Raga, & Godley, ; Vélez‐Rubio, Estrades, Fallabrino, & Tomás, ), marine debris (Bugoni, Krause, & Petry, ; Santos, Andrades, Boldrini, & Martins, ; Tourinho, Sul, & Fillmann, ), boats and others watercrafts (Hazel & Gyuris, ; Work, Balazs, Summers, Hapdei, & Tagarino, ), hopper dredges (Goldberg et al, ), and oil and natural gas exploration/production activities (Stacy et al, ; Ylitalo et al, ). Natural factors, including diseases such as fibropapillomatosis (FP) (Chaloupka, Work, Balazs, Murakawa, & Morris, ; Reis, Pereira, et al, 2010), other neoplasms (Orós, Torrent, Calabuig, & Déniz, ), endoparasitosis (Flint et al, ), septicaemic processes (Goldberg et al, ), and hypothermia (Shaver et al, ; Vélez‐Rubio, Trinchin, Estrades, Ferrando, & Tomás, ), are also reported as causes of stranding.…”

Data on stranded sea turtles were examined between 2010 and 2016 along the northern region of Rio de Janeiro state and between 2016 and 2017 in the southern region, looking for spatio‐temporal patterns and determining which factors contributed to their mortality. A total of 12,162 strandings of all five species that occur in Brazil were recorded, with Chelonia mydas being the most common (89.9%). Sea turtles use the Rio de Janeiro coast as a feeding and/or migration area. The intense upwelling (October to April) may be an important factor for the sea turtles feeding in this region, mainly for Eretmochelys imbricata and Dermochelys coriacea, which had a higher number of strandings during this period. Areas further north of the study area include an important nesting site for Caretta caretta in Brazil, which explains the higher concentration of strandings of subadults/adults of this species in this region and during its nesting season. Many anthropogenic threats to sea turtles were documented, mainly incidental capture in fisheries and marine debris, indicating possible hotspots for these threats in the regions of Sepetiba and Guanabara Bays, Cabo Frio, and São Francisco de Itabapoana. Among the natural causes of strandings, the primary factors were chronic illness, endoparasites, and fibropapillomatosis. However, pollution may also be an indirect threat, which negatively affects these animals through reduced health and immunosuppression, leaving them more susceptible to opportunistic diseases. These data are valuable for directing and implementing specific and local mitigation measures along the Rio de Janeiro state coast, such as avoiding bycatch hotspots through fleet communication programmes and/or area and seasonal closures, enforceable legislation, effective penalties and proper waste management.
