“…From previous studies, isomeric ratios like Ant/(Ant + Phen), Flt/(Flt + Pyr), BaA/(BaA + Chry), IndP/(IndP + BghiP) BaP/BghiP and others LMW/HMW, COMB/TPAHs, PAH(4)+( 5 Though PAHs compositional may be used in some instances in distinguishing sources, it's not the only ultimate tool because of some other limitations. LMW/HMW can also be used to differentiate emissions from pyrogenic source and petrogenic sources (E ong, et al, 2016;Soclo, Garrigues, & Ewald, 2000). LMW/HMW ratio from this study in I ekporo Creek ranged between 0.00 to 3.08 and this revealed that most of the samples (94.4%) had LMW/HMW values less than < 1 while only 5.6% LMW/HMW > 1.…”

The occurrence and level of polycyclic aromatic hydrocarbons (PAHs) in the mangrove sediment of the Ifiekporo community in Warri South Local Government Area of Delta State were assessed in this study. A total of 10 sediment samples were collected from 10 sites along the Ifiekporo Creek. The extraction of PAHs from the sediment samples was achieved using the PAHs Analytical Test Method (USEPA 8270). This method measures individual concentrations of extractable PAHs in samples. The aliphatic and poly-aromatic hydrocarbons were quantified within C11-C22. The basic GC parameters for the analysis of polyaromatic hydrocarbons were analyzed using the Gas Chromatograph-Mass Selective Detector (GC-MSD). The individual PAH concentration in mangrove sediment samples varies from Not Detected (ND) to 3.47 µg/kg. The PAHs concentration of 3.47 µg/kg was highest in sampling point 5 across the sampling points. The PAH source apportionment employing isomeric ratios and multivariate statistics indicated both pyrogenic and petrogenic source inputs in sediment samples. The PAHs homologous distribution sequence for sediment is 3-ring > 2-ring > 1-ring > 6-ring. The sediment samples are mostly dominated by LMW PAHs. The result of the ecological risk assessment in the study area indicates that there is low ecological risk associated with PAH exposures in sediment. These results provide data on the concentrations and compositional patterns of PAHs, which is useful in understanding the effects, sources, fate, and transport of PAHs in sediment in the study area, as well as providing relevant information for environmental quality management and forensic studies.

“…But this present study showed the dominance of HMW-PAHs and a pyrogenic source of PAHs in other study locations (Bonny, Ibeno and Iko town) which is consistent with the report of Nwaich and Ntorgbo 26 who noted that other sources of PAHs contamination could contribute at different degrees. In a related study on the PAH burden in some fish species from Bonny and Cross River estuaries, in the Niger Delta, Effiong et al 27 noted that the compositional pattern of PAHs in the Niger Delta showed the dominance of three and fourringed PAH congeners and they were the greater source of PAH burden. The diagnostic ratios showed that the PAH burden emanated from pyrogenic or combustion activities.…”

Background and Objective: Bivalve shellfish such as Bloody cockle (Anadara senilis), Donax clam (Donax rugosus), Knife clam (Tagelus adansonaii) and Mangrove oyster (Crassosstra gasar) are the most abundant soft-bodied invertebrate inhabiting the brackish and intertidal mudflat of the Niger delta. They are considered as nutritious and healthful food items as well as a biological matrix for environmental monitoring. The study investigated compositional patterns and tissue concentration of polycyclic aromatic hydrocarbons (PAHs) in bivalve shellfish. Materials and Methods: Four samples of bivalve shellfish harvested from four locations in the Niger delta were assessed for PAHs concentrations through the use of Gas chromatography. Results: Results obtained from the compositional pattern of PAHs indicated the dominance of low molecular weight PAHs at Andoni location while other study locations were dominated with high molecular weight PAHs. The tissue burden of PAHs indicated bloody cockle (53.75 :g kgG 1 ), knife clam (50.00 :g kgG 1 ), mangrove oyster (40.34 :g kgG 1 ) and Donax clam (36.94 :g kgG 1 ), while diagnostic ratio showed that the PAH burden originated from the petrogenic source at Andoni while those of other locations were from pyrogenic or combustion processes. PAHs are recognized as major contributor to environmental pollution affecting aquatic ecosystems under the influence of human mediated activities. Conclusion: From the results obtained, the compositional pattern of PAHs in bivalve tissue found in the study locations are typical of an areas under the influence of intensive anthropogenic activities. Therefore bivalve shellfish harvested from these locations can induce potential deleterious health effects to the consumers.

“…Changes in PAH concentrations and fractions as a result of frying can be attributed to the interaction of long frying times, cyclization, and the transition from low-ring to high-ring PAHs as the temperature of cooking rises (Iwegbe et al, 2020). Concerns have been raised regarding the appearance of a signi cant proportion of pyrene and uoranthene in some oil samples, as these compounds are carcinogenic when combined with B(a)P (An et al, 2017;E ong et al, 2016;Stepanov et al, 2010). Flouranthene concentration in mixed vegetable oil after the third fry with beans cake and in the unused oil were below the detection limit, at 30µg/Kg respectively and 36-74 µg/Kg were measured for pyrene in the unused oil and third fry, respectively, with a Similar pattern observed for other components of oil samples.…”

Boiling, roasting, baking and frying are all food preparation methods that can have a significant impact on food quality. Frying and baking are popular methods of preparing finger food in Ghana. It is common among Ghanaians to use the same batch of oil to fry food multiple times. In this study, the effect of multiple frying on the composition and concentration of PAHs in three commonly used cooking oils—soybean, mixed vegetable, and sunflower—was examined. PAH levels were measured in fresh (unused) as well as used oil samples. Bean cake, doughnuts, and plantain chips were fried alternately using the three types of oil, and PAH levels were quantified. Gas chromatography and mass spectrometry were used to determine the PAH content of the oils and finger foods. PAHs, mostly low-ring were found in the unused (fresh) oil. The total concentration of the PAHs in the fresh oil was 223 µg/kg. A total of 15 individual PAHs congeners were recorded in the oils after repeated fries. The sum concentrations of the 15 PAHs was 15612µg/kg. It was also discovered that the PAH composition differed depending on the type of oil, finger food, and number of frying cycles. The percentage increase for high molecular PAH (HM-PAH) in the second and third fry sessions was, on average, 22% and 40%, respectively. The PAHs levels recorded in the edible oils after repeated fries were above the recommended guideline limit. It is therefore recommended that repeated use of edible oil in frying should be avoided to protect public health.
