Background. Polycyclic aromatic hydrocarbons (PAHs) are toxic contaminants and pose health risks to humans and the ecosystem due to their persistence in the environment. Objectives. This study determined the concentrations of PAHs in sediment, two species of fish (Drepane africana and Pomadasys jubelini), crabs (Callinectes amnicola) and shrimps (Penaeus notialis) around the Atlas Cove jetty, Lagos, Nigeria. Methods. Polycyclic aromatic hydrocarbons were extracted from fish, shrimp, and crabs that were purchased from local fishermen. Sediments were collected at five locations impacted by ship movement and cargo offloading around the Atlas Cove jetty during the period of June to August 2016, using standard methods. Potential toxicity of PAHs in the sediments on the surrounding aquatic organisms was assessed. The PAHs were analyzed using gas chromatography-mass spectrometry. Human health risk assessment was calculated from biota using dietary daily intake and carcinogenic potencies of individual PAH concentrations. Results. A total of 17 PAH congeners were detected in sediment samples and ten were detected in biota samples. Concentrations of total PAHs obtained in sediment and fish samples ranged from 2.15 - 36.46 mg/kg and 11.89 - 71.06 mg/kg, respectively. The total PAHs concentration pattern follow the order of P. notialis > C. amnicola > P. jubelini (whole) > D. africana (whole) > D. africana (fillet) > P. jubelini (fillet) > sediment. Concentrations of total PAHs were higher in whole fish than in fillet samples (muscle) in both fish species. High values of PAHs were recorded in the dietary intake (0.10 - 2.33 mg/kg body weight/day) of the organisms. Toxic equivalent quotient values (0.01 to 0.10 mg/kg) were observed to be higher than the screening values (0.0014 to 0.0599 mg/kg). In the muscle of Drepane africana and Pomadasys jubelini, splitting and atrophy of the muscle bundles were observed. Conclusions. The concentrations of PAHs in analyzed sediment and organisms were higher than the maximum permissible limit of the United State Environmental Protection Agency (USEPA). Most of the detected PAHs were of petrogenic origin, which is an indication that anthropogenic activities were influencing PAH concentrations. Competing Interests.

“…Many of these chemicals, which most times are carcinogenic accumulate in fish and shellfish, binding to fatty tissues or muscle tissues (Copat et al, 2013). Dietary exposure is, therefore, the predominant route of exposure of humans to these contaminants (Wu et al, 2012).One of such contaminants is PAHs.…”

“…PAHs are persistent organic compounds (POPs) with a wide range of distribution in various environmental media (Wu et al, 2012). They are important components of crude oil and have been reported in areas of crude oil spills (Awajiusuk, 2015).…”

“…PAHs have been reported in different environmental media including fish and shellfish in this region (Nkpaa et al, 2013;Nwaichi and Ntorgbo, 2016).PAHs have received considerable attention in recent times because of their highly carcinogenic potentials (Wu et al, 2012) therefore, be reasonable to comprehend that residual levels of PAHs in fish and shellfish, especially edible species could have a great effect to human health (Llobet et al, 2006). Sadly, only very few studies have paid direct attention to the public health consequences of eating PAH contaminated aquatic species used as food.…”

The concentration of polycyclic aromatic hydrocarbons (PAHs) in Fish (Mullet fish-Mugil cephalus) and Shellfish (Tiger prawn-Penaeus Monodon and crab-Uca tangeri) samples from fishing areas in Amariaria Community, downstream of Bonny River, Southern Nigeria, were assessed to determine possible human health risk associated with consumption. Mean levels (mg/kg) of total PAHs ranged from 0.059 to 0.126 in fish, 0.015 to 0.106 in prawn and 0.057 to 0.063 in crab. A considerable predominance of the 3 and 4-rings PAHs in all the matrices was observed with benzo (a) anthracene dominating in all three species. Estimated daily intake (EDI) of PAHs through consumption of fish ranged from 0 to 0.0005 mg/kg/day, for prawn, 0 to 0.0002 mg/kg/day and for crab, 0 to 0.0002 mg/kg/day. EDI values were, however, lower than the reference dose (RfD) indicating low risk from consumption. Results of the estimated excess cancer risk (ECR) for Benzo (a) anthracene in fish, however, suggests that lifetime exposure to Benzo (a) anthracene through fish consumption would result in cancer risk.

Concentrations of Persistent organics (Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), metalloid (As) and heavy metals (Fe, Zn, Mn, Cu, Ni, Cd. V, Cr, Pb, Hg) were measured in fish (Clarias gariepinus) samples collected from selected stations (S1, S2 and S3) along the stretch of Ovia River, Southern Nigeria, to assess the potential risks to humans consuming fish from the river. Acenaphthylene (AcPY), PCB 18 and iron (Fe) were the most dominant residues with mean concentrations ranging from 0.002 to 0.128, 0.001 to 0.003 and 175.97 to 255.52 mg/kg respectively. The most carcinogenic PAH, Benzo(a)pyrene (BaP) in S3, all the PCB congeners, cadmium (Cd), and lead (Pb) concentrations in the three stations were observed to be above EU recommended guideline values for food safety. Concentrations of dioxin-like PCB congeners, 77, 105, 114 and the sum of carcinogenic PAHs also contributed to the toxic burden of these contaminants in fish. The estimated cumulative THQ for the assessed metalloid and heavy metals indicates health risks from exposure to metalloid and Heavy metals through fish consumption.
