“…Results showed that the TEQ values for all the fish species were below the SV of 3.556 mg/kg ( Table 4 ). Results from this study, were not consistent with the report of Ikue et al [43] , in a study of PAH contaminants in Chrysichthys nigrodidatatu in Rivers State, Nigeria, who reported calculated TEQ values above estimated screening values, indicating potential health effects. Nozar et al [44] also reported higher TEQ values when compared to calculated SV values for PAH in seafood (fish, crab, and bivalve) in Iran at a consumption rate of 55.1 g/d.…”

Polycyclic Aromatic Hydrocarbons (PAHs) levels in four commonly consumed smoked fish species from markets in Southern Nigeria were assessed to evaluate possible human health risks associated with consumption. Varying levels of PAH congeners were observed in the fish tissues with the highest total concentration of PAHs in Scomber scombrus. High concentrations of benzo(a)pyrene was observed in Clarias gariepinus and Ethmalosa fimbriata with values above the guideline value of 0.05 mg/kg. The Dietary Daily Intake (DDI) value for total PAHs (∑PAHs) was highest for S. scombrus while the DDI value for the total carcinogenic PAHs (∑CPAHs) was highest for E. fimbriata. Carcinogenic human health risk assessment using carcinogenic toxic equivalents (TEQ), indicated that consumption of E. fimbriata has a higher potential to cause carcinogenic risks. TEQ values for all the fish species were however, below the estimated screening value (SV) of 3.556 mg/kg, while the estimated cumulative excess cancer risk (ECR) for E. fimbriata and C. gariepinus and PAH4 index for all the assessed fish species exceeded threshold values indicating potential carcinogenic risk from consumption.

“…The results of the present study are in agreement with a study of PAHs contaminants in Chrysichthys nigrodigitatus in Rivers State, Nigeria, where Patrolecco et al reported TEQ values above estimated SVs 48,49. In addition, higher TEQ values were reported when compared to calculated SVs for PAHs in seafood (fish, crab, and bivalves) in Iran, indicating potential health effects 5.…”

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.

“…Changes in the action of antioxidant enzymes, damaged DNA bases, the result of protein oxidation and lipid peroxidation products are all examples of oxidative stress (Sarker et al 2018). In addition, PAHs may cause the most commonly used biochemical indicator in environmental pollutant biomonitoring to be cytochrome P450 1A (Ikue et al 2016). It is involved Gaber et al in the metabolism of xenobiotics and drugs (Parente et al2008).…”

Effect of polyaromatic hydrocarbons on cellular cytochrome P450 1A induction

The detection of cytochrome P450 1A in S. rivulatus liver and gills was used as a biomarker for the exposure to polyaromatic hydrocarbons (PAHs) as organic pollutants along the Bay of Alexandria, Egypt. PAHs were determined in both sediment and S. rivulatus tissues in Abu Qir Bay, Alexandria as a test area and the Matrouh coast as a control area. High levels of PAHs in Abu Qir Bay area and ratios of specific PAH compounds indicate the petrogenic origin of hydrocarbons. Both antioxidant activity and oxidative stress markers increased significantly. The protein expression of P450 1A in the liver and gill of S. rivulatus was markedly induced. Moreover, the toxicity in fish organs was supported by histopathological observations. These data suggest correlation between bioaccumulated PAH and P450 1A induction and provide strong evidence of the importance of P450 1A as a biomarker of the exposure of S. rivulatus to xenobiotics.
