Research ArticleOpen accessIn the author namesMutagenic Screening of Crude Oil Fractions Using Modified Ames Test and Allium cepa (Linn) AssayOlufunsho Awodele, Alade Akintonwa, Sunday O. Olayemi et al.Problem statement: Crude oil which may be broadly characterized as paraffinic or naphthenic is a complex mixture of alkanes, cycloalkanes and aromatic hydrocarbons. About 500,000 workers are employed in crude oil exploration and production worldwide. There have been reports of occupational exposure during drilling, pumping and transportation of crude oil, including maintenance of equipment used for these processes. Thus, skin … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 1 · 31 Jan 2010 · 8,629 accessesView PDFCite

Olofinnade et al.Problem statement: The pharmaceutical industry is a major contributor to industrial wastes globally. Effluents from this industry are usually discharged into the environment and when not properly handled and disposed, they affect both human health and the environment. Approach: This study evaluated the mutagenic potentials of effluents from six pharmaceutical companies in the Lagos province of Nigeria using modified Ames … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the author namesPhenanthrene Contaminated Soil Biotreatment Using Slurry Phase BioreactorM. Arbabi, M. Sadeghi, Ch. AnyakoraProblem Statement: Polycyclic Aromatic Hydrocarbons (PAHs) are suspected toxins that accumulate in soils and sediments due to their insolubility in water and lack of volatility. Slurry-phase biological treatment is one of the innovative technologies that involve the controlled treatment of excavated soil in a bioreactor. Due to highly soil contamination from petroleum compounds in crude oil extraction and also oil … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,758 accessesView PDFCite
Research ArticleOpen accessIn the author namesOrganochlorine Pesticide Residues in Fish Samples from Lagos Lagoon, NigeriaDavid Adeyemi, Grace Ukpo, Chimezie Anyakora, JohnPaul UnyimaduThe organochlorine pesticide (OCPs) residues were measured in three species of fish Tilapia zilli (Red belly Tilapia), Ethmalosa fimbriata (Bonga Shad) and Chrysichthys nigrodigitatus (Catfish). These fish species are a significant part of the diet of residents of Lagos Nigeria. The organochlorine pesticides analyzed include DDT(pp'1,1,1-trichloro-2,2-bis-(4-chlorophenyl) ethane), DDD, DDE (pp 1,1-dichloro-2, 2-bis-(4-chlorophenyl) ethylene, HCH (gamma 1,2,3,4,5,6-hexachlorocylohexane, HCB (hexachlorobenzene),Dieldrin (1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a octahydro-1,4,5,8 … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 9,904 accessesView PDFCite
Research ArticleOpen accessIn the author namesA screen for Benzo(a)pyrene in Fish Samples From Crude Oil Polluted EnvironmentsChimezie Anyakora, Mohsen Arbabi, Herbert CokerSeveral studies have shown that exposure to Benzo(a)pyrene increases the risk of cancer. In this study several fish samples from Niger the Delta region of Nigeria were screened for the presence of Benzo(a)pyrene. The study was carried out using Gas chromatograph coupled to a mass spectrometry detector. Benzo(a)pyrenes in the samples were identified through both retention time match with authentic … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,766 accessesView PDFCite
