“…Prior to this, other authors reported TEQ levels that were consistent with what found here (Fossi et al, 2004;Jiménez et al, 2000). TEQs reported in this study were below values found in Mediterranean sperm whales, pilot whales and bottlenose dolphins (Bartalini et al, 2019;Pinzone et al, 2015;Romanić et al, 2014;Storelli et al, 2007;Storelli and Marcotrigiano, 2003).…”

“…The high lipid content of Clarias gariepinus (Ezemonye et al, 2015) favours their trapping of pesticides in their lipid stores. This is supported by Romanic et al (2014), who observed a positive correlation between lipid content of fish muscle and bioaccumulation of pesticide. The bottom feeding modes of Clarias gariepinus can also be attributed to the higher prevalence of atrazine in the fishes due to the likelihood of exposure to contaminated sediments and sinking feeds as reported by Biego et al (2010).…”

Extensive use of atrazine as herbicide in crop farming in Nigeria may lead to its accumulation in fish feed ingredients or aquatic ecosystem from aerosol or by runoff resulting in its residue in aquatic animals. Atrazine residues were determined in fish feed and catfish (Clarias gariepinus) fillets from commercial aquaculture farms in Southwestern Nigeria by matrix solvent particle dispersion and quantification using an ELISA kit. The mean atrazine concentrations in feed and fish were about 1.3-1.5 μg/kg and 1.4-1.8 μg/kg respectively. Atrazine was mostly detected in catfish from Ogun State (91.3%) and feed from Lagos State (80.0%) with mean concentrations of 1.4 AE 0.4 μg/kg and 1.5 AE 0.5 μg/kg, respectively. Mean atrazine concentration in catfish samples from Lagos State was significantly higher (P < 0.05) than the mean concentration in catfish samples from Ogun State. This study showed that the Estimated Average Daily Intake (EADI) of atrazine in fish samples from the selected states were below the Acceptable Daily Intake (ADI) value of 6 μg/kg for herbicide residues and thus within safe limit but their presence in fish is a cause for concern.

“…Chromium was only detected in water from the study site and had a value of 0.008±0.001µg/ml. Generally, catfish may have accumulated more heavy metals than mullet in this study probably due to its high lipid content [46].…”

The concentration of selected endocrine disrupting chemicals in tissues of Chrysichthys nigrodigitatus (catfish) and Liza falcipinnis (mullet) obtained from Choba river in Rivers State, Nigeria was analyzed to determine their levels and possible hazard for human consumption. Pesticides and polychlorinated biphenyls were assessed using gas chromatography coupled with electron capture detector. Heavy metals analysis was carried out using atomic absorption spectrophotometer. The concentration of pesticides ranged from 0.0013±0.0002 to 0.0130±0.0002 µg/l and 0.0077±0.0000 to 0.0390±0.0001µg/g in water and sediments, respectively. Similarly, pesticides concentration ranged from 0.0001±0.0000 to 0.0171±0.0002µg/g and 0.0002±0.0001 to 0.0385±0.0002µg/g respectively. The concentration of PCBs in analyzed fish ranged from 0.2439±0.0001 to 0.2683±0.0003µg/g in the muscle and liver, respectively. Heavy metal concentration ranged from 0.004±0.001 to 0.460±0.002µg/g for cadmium and mercury, respectively. Risk hazard estimates of dichlorodiphenyltrichloroethanes, Chlordanes, hexachlorobenzene, and heavy metals (Cd, Cr) in the studied fishes showed no potential adverse effect to human consumption at the observed concentrations. Mercury was high in all fish analyzed with a quotient value greater than unity indicating potential mercury poisoning. The cancer risk was also evaluated according to USEPA, (2005) and was within acceptable risk range of 10-4. Thus exposed populations are not at cancer risk through consumption of fish.
