“…The extraction procedure was repeated by adding 20 mL of the mixture of DCM and acetone and then allowed to undergo ultrasonication. The extract was combined and later cleaned up [13,14]. For the clean-up experiment, an SPE column was packed with cotton wool containing anhydrous sodium sulphate and silica gel.…”

Fish is easily contaminated from water prone to water pollution. In this study, the levels of polycyclic aromatic hydrocarbons (PAHs) in fish samples processed, using three methods and marketed in Makurdi, Benue state, were determined. The samples were coded as SF (Smoked Fish), SD (Sundried) and FD (fried) fish samples. PAHs in the samples were quantified, using gas chromatography – mass spectrometer (GC-MS). The Ʃ16PAH concentrations were in the range of 0.2- 10.0 mg/kg. Both LPAHs/HPAHs and the binary diagnostic ratios of PAHs indicated pyrogenic and petrogenic sources Ʃ16PAH and their dominant PAH ring-types were separately computed for each sample. The six-membered ring PAHs in smoked fish was 32.07% (with Bezo(ghi)perylene as most dominant). High levels of six member ring PAHs (Dibenz(a,h) anthracene) were also found in Sundried fish and fried fish contain Dibenz(a,h) anthracene. Generally, the PAHs concentrations in the samples, pointed more at pyrogenic than the petrogenic source. With exception of the five and six membered rings, estimated PAH levels were within the NAFDAC permissible limits.

formed during incomplete combustions of organic substances but few to be mention such as cigarettes, coal etc. They are usually found as a mixture containing two or more compounds such as soot. The emissions of PAHs in Nigeria have contributed significantly to the environment and live of aquatic organisms. Thus, this paper reviewed the contamination of polycyclic aromatic hydrocarbon (PAHs) in the water, sediments and organisms in inland and coastal waters. Methodology: Literatures of relevant and previous studies of polycyclic aromatic hydrocarbons in the water, sediment and organism within and outside Nigeria were reviewed. Results: The contamination of polycyclic aromatic hydrocarbons (PAHs) was known to be carcinogenic, mutagenic, teratogenic and can cause adverse effect on human health, wildlife and aquatic lives with no report on mammals in the aquatic environments. Conclusion and Recommendation: Polycyclic aromatic hydrocarbons (PAHs) reviewed displayed different effects caused in the lives of human and aquatic organism based on the concentration level. Their sources were more of anthropogenic than natural source with varied concentrations at various source points due to different activities in question. The positive impact of polycyclic aromatic hydrocarbon on fish and other aquatic organisms as a result of bioconcentration, biotransformation and biomagnification become a threat to humans that rely on eighty percent of aquatic resources. Therefore, conceived efforts should be made to reduce these effects, general public monitoring of polycyclic aromatic hydrocarbon on discharge sources in the biosphere.
