“…The findings from this study corroborated the report of pyrogenic and petrogenic PAHs at levels exceeding maximum tolerable standards outlined by different regulatory bodies [9]. Contrary to this study, the increased level of LPAHs found in waters of the Atlas cove in Lagos State in Nigeria was an indication of increased petrogenic inputs [37], and the predominance of petrogenic LPAHs in hand-dug wells of South-Western Nigeria [38].…”

Ten water samples were collected along the Imiringi water channel, cutting across several sub-communities of the upstream to downstream sections of the river. All samples were collected in the month of August 2019, reflecting increased tidal movement of water and aggravated pollutants redistribution which is typical of the rainy season. Analysis was carried out using the HP 6890 Plus gas chromatograph – flame ionization detector (GC-FID). The rate of ionization of each PAH component was directly proportional to the obtained concentration. The total concentrations of 14 PAHs ranged from <0.01 to 300.1 µgL-1, with the high molecular mass PAHs (4-6 ring HPAHs) observed as the most important fractions showing 82.4% distribution. Also, the low molecular mass PAHs (2-3 ring LPAHs) were found in trace concentrations, accounting for 17.6% of total PAH mass. The application of PAH source diagnostic ratios revealed vegetation and coal combustion as primary sources, followed by petroleum combustion, and then, petroleum sources. Correlation cluster analysis (CCA) and principal component analysis (PCA) showed discrete localization for samples of stations OL1, OB2 and OS4. The pyrogenic inputs are most likely from runoffs of seasonally burnt vegetation at near-coastal farmlands as well as leachates from surrounding waste-dumpsites. Petroleum sources may have resulted from neighbouring oil installations and illegal oil bunkering sites. Overall, the study is aimed at identifying the most important contributing sources of polycyclic aromatic hydrocarbon (PAH) micro-pollutants in the aquatic environment.

“…Also, the current work showed lower concentrations than those obtained from hand-dug wells at Ile-Oluji, Nigeria, where concentrations ranged from <0.01 to 11.3 ng/µL. Furthermore, LPAHs (2-3 aromatic rings) consisted of about 95% of the total PAH mass, with the remaining 5% being associated with the 4-6-membered aromatic rings [38].…”
