A comparison of the bile carcinogenic polyaromatic hydrocarbon level (ppm) in Mugil spp. collected from the six sites
Source publication
The total polyaromatic hydrocarbons (TPAH) and the total polychlorinated biphenyls (TPCB) that originate from oil spills in sea and ocean waters are toxic to fish and their offspring. The authors compare the levels of organic contaminants (TPAH and TPCB) recovered from the bile versus the dorsal muscles of 120 individual Mugil spp. that were harves...

... means of the total bile CPAH in Mugil spp. harvested from the six sites ranged between 0.011 ppm and 0.025 ppm (Fig. 4). No statistical difference was observed among the six means of the total bile cPAH obtained from the Mugil spp. harvested from the six sites (p >0.05). The bile TPAH level correlated significantly to the bile cPAH in Mugil spp. at a confidence level of 90%, resulting in a positive slope regression equation of Y (bile TPAH) = 0.0057X ...

... range of the cPAH in the bile of Mugil spp. was between 0.011 ppm and 0.025 ppm (Fig. 4). The level of cPAH in the bile of other fish has been reported in the literature (4). In the bile of the English sole (Pleuronectes vetulus), the range of a marker of exposure to cPAH is reported to be between 0.0158 ppm and 0.054 ppm. The range of the marker in the bile of the same fish harvested from another site was between 0.0169 ...

Recent development of a large oil field in the Eastern Province of Saudi Arabia achieved real time well placement above a tar mat by utilizing Formation Pressure While Drilling (FPWD) and Saudi Aramco's Pyrolytic Oil-Productivity Index (POPI). Placement of 6 ⅛ in. horizontal power water injector wells in close proximity above an impermeable, undula...
One of the most important factors of the successful production, transportation and utilization of the highly viscous oil such as bitumen is viscosity reduction. Several approaches including emulsification of bitumen as dispersed particle in the continuous aqueous phase containing surfactant have been investigated and practised. However, recent prog...
Air injection is an effective technique for improved oil recovery in light oil reservoirs. It is speculated that the main mechanism of the process is via spontaneous low-temperature oxidation (LTO) to consume oxygen and generate “flue gas” that displaces oil out of the reservoir. In this study, laboratory experiments have been conducted to study th...

Polycyclic aromatic hydrocarbons (PAHs) are a group of persistent organic pollutants, some of which are mutagenic and carcinogenic so PAH concentrations in fish used for human consumption are crucial to assess impact to human health. Total PAH concentrations in muscle and liver of mullets Chelon bispinosus from the Bay of Porto Grande (Cape Verde) (four sites in the bay and a control) ranged from 112.7 to 779.5 and 291.5 to 7548.7 ng/g d. w., respectively. Two and three ring PAHs were the most frequent (72.8 to 90.8% in the muscle and 75.9 to 98.3% in the liver), but levels of carcinogenic PAHs (mainly Dibenzo (a,h) antracene) in certain sites (CN and PG) are of concern. Results reflect a chronic PAH pollution in the bay and sources are a mixture of anthropogenic (petrogenic and pyrolytic) and natural sources, making their identification extremely complex. Although, BaP levels were below the threshold established by Cape Verde and the European Union, BaPEs levels in muscle ranged from 0.28 to 3.66 ng/g w. w. and BAPEs and TPAHs exposure for the average adult was 0.02 to 0.26 and 1.6 to 11.2 µg/day, respectively. Further knowledge of PAH concentrations in other species are necessary for a proper environmental risk assessment policy.
