“…In Nigeria, imported petroleum products are stored in tank farms, many of which are in Lagos, and these products are distributed to other parts of the country through pipelines connected all over Nigeria. Nigeria has a wide pipeline network and depots for distributing refined petroleum products (Renner et al 2008). There are about 5000 km of pipelines and about 20 oil depots altogether in Nigeria (Adewuyi and Olowu, 2012).…”

“…Frequent petroleum spillages, impacting the terrestrial ecosystem, occur due to vandalization of the pipelines. In Nigeria, a total number of 2097 oil spill incidents were recorded between 1997 and 2001 (Renner et al 2008). In 2005, 117 cases of fire outbreak were recorded as a result of pipeline vandalization and rupture of Nigerian National Petroleum Corporation (NNPC) pipelines (Renner et al 2008).…”

According to Shell Petroleum Development Company of Nigeria Limited, in the Niger Delta region alone, 1301 oil spill incidents were recorded around SPDC facilities between 2007 and March 2013 resulting from equipment failure, corrosion or human error (Doherty, 2014) Lagos State contains networks of petroleum distribution pipelines, depots, and petrol filling stations, with underground tanks which leak petroleum products into the terrestrial environment.…”

Background: Monocyclic aromatic hydrocarbons are toxic compounds which are major components of petroleum products. This study was aimed at identifying histopathological alterations and changes in antioxidants defense systems in Eudrilus eugeniae (earthworm) that can be used as good battery of biomarkers for early detection of pollution associated with hydrocarbons. The toxicological evaluations of benzene, toluene, xylene, and ethylbenzene (BTEX) were carried out against E. eugeniae. Earthworm samples were collected around oil impacted and control sites. The effect of BTEX was investigated on oxidative stress markers of E. eugeniae. Results: Results showed that xylene (1.2 mg/kg) was the most toxic compound, followed by toluene (1.3 mg/kg), ethylbenzene (1.4 mg/kg), and benzene (1.9 mg/kg). The biochemical responses revealed an increase in malondialdehyde level and decrease in the level of superoxide dismutase, catalase, glutathione, and glutathione-S-transferase in E. eugeniae collected around the oil impacted area of Ijegun. The results from the laboratory studies were confirmed in the field studies. Significant histopathological alterations in the whole organisms were observed in both field and laboratory studies. The pathological findings include cellular and epidermal degeneration, and presence of pigment and inclusion bodies. Conclusion: The results reflect the biological effects of hydrocarbon pollution, thus confirming the relevance of histopathological and antioxidant enzymes as biomarkers for detection of hydrocarbon pollution during environmental monitoring programs.

“…Despite high reportage of oil spills and illegal oil activities in the Nigerian coastal water, there is scarcity of report or documentation on the effect of crude oil or its fractions on tissue biochemistry of an important brackish species Tympanotonus fuscatus, despite the efforts towards heavy metals accumulation and total hydrocarbon content and mortality of this species in post spill incidence (Daka et al, 2006;Ideriah et al, 2006;Egonmwan, 2007;Renner et al, 2008;Benson and Essien, 2009;Ewa-Oboho and Otogo, 2009;). This study investigates changes in the enzymes of the periwinkle (Tympanotonus fuscatus) exposed to diesel a refined product of crude oil.…”

The effect of mild concentrations of diesel (10.40,15.60,21.00 and 26.00 mg/l) on some biochemical parameters such as Aspartate transaminase (AST), Alanine transaminase (ALT), and Alkaline phosphatase (ALP), in the tissue of periwinkle (tympanotonus fuscatus) were examined using a renewal static bioassay for six days. The activities of the enzymes were measured on 120 specimens of periwinkle of size between 4.5-5.5cm lengths. The result of AST activity in the muscle showed either an increased or decreased activity against the control. The activity of ALT showed significant (p=0.05) decrease in all the test concentrations. ALT also showed significant difference (p=0.05) which were either higher or lower than the control value. In the viscera, activity of AST significantly increased (p=0.05) than that of the control. ALT activity was significantly increased (p=0.05) above the control except at 10.40ml/L where a significant decrease (p=0.05) was observed. Significant increase (p=0.05) was observed in the activity of ALP above the control value except at 10.40ml/L. The result of the tissue enzyme activities indicated alteration in the biochemistry of tympanotonus fuscatus and therefore could be used as a biomarker of aquatic pollution and toxicities.

Background:The study was aimed at investigating the bioaccumulation of BTEX in Parachanna obscura, its enteric parasite, Procammalanus sp, water and sediment collected from Lekki lagoon in Lagos, Nigeria. Parasite intensity, antioxidant enzymes, and lipid peroxidation activities were also investigated in the fish. Ninety-two (92) samples of P. obscura were investigated for BTEX and parasitic infection for a duration of six months. Physicochemical parameters were measured in-situ using a handheld multiparameter probe (Horiba Water Checker Model U50). BTEX was analyzed using Agilent 7890B gas chromatography system with FID and 7683 series injectors. Histopathological analysis of the fish intestine was conducted following standard histopathological measures. Results: BTEX was not detected in the sediment but m+p-Xylene and O-Xylene 6.938 µg/g and 5.854 µg/g were detected in the water respectively. P. obscura showed high accumulation of total BTEX in the intestine than in the liver especially Benzene even though benzene was not detected in the water. The concentration of BTEX was similar in ranges for the parasitized and unparasitized tissues. The parasite recovered from the fish was Procamallanus spp. The parasite showed little or no depurative capacities for BTEX. The decrease in superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH) in conjunction with an increase in Malondialdehyde (MDA) characterized relatively higher susceptibility in the fish. Lipid peroxidation damage is one of the foremost damages to cell components that could be inflicted by BTEX. Conclusions: It is therefore pertinent that regular monitoring of BTEX in the water body as well as in the biota should be undertaken and regulatory agencies need to ensure that all the oil depots and tank farms situated along the Lagos lagoon treat all their storm waters and effluents in order to reduce its hydrocarbon level before discharge into the lagoon to safeguard human health and integrity of the aquatic habitat.
