Crude oil, women and the environment: a case study of Delta state of Nigeria
(2001) Olaifa, F. E.; Olaifa, A. K.; Lameed, G. A.
The study of effects of petroleum pollution on the general environment with peculiar relevance to women in Delta State was carried out for a period of nine months, by using structured questionnaire and personal observations. The study was basically focused on women of all age groups and generalized all sources of pollution in the area. Among all, oil spillage to the rivers, streams, and farmlands (44.8%) was most rated, while other sources like fish (62.1%), and effect their occupational status that is based on peasant farming (33.7%) and fishing (52.1%). However, there is high significant effect (P<0.05) of the sources of pollution to the environment related tow omen livelihood in the area. While responses to the effect were in form of cooperative (2.3%), individual (2.1%), the oil companies compensation (41.9%) and sometimes government assistance (33.2%). It was therefore suggested that women should be given advantage of both formal and informal education, adequate supply of funds in form of loan, with other amenities such as good source of water, alternatives to fishing and farming to alleviate the poverty conditions that oil spillage had caused.
Field and experimental investigations of an outbreak of African swine in Nigeria
(2005) Otesile, E. B.; Ajuwape, A. T. P.; Odemuyiwa, S. O.; Akpavie, S. O.; Olaifa, A. K.; Odaibo, G. N.; Olaleye, O. D.; Adetosoye, A. I.
An African swine fever (ASF), characterized by a mortality reaching 50 to 100 p. 100 in different herds were diagnosed with high domestic pigs loose in Delta State in Nigeria in August 1998. The etiologic confirmation of the PPP was obtained by virus isolation, PCR and sequencing of 280 base pairs a segment of the gene encoding the major protein (VP72) capsid. The experimental infection of animals with infected blood caused fevers, with the highest peaks two to four days after infection, death followed five to six days after infection. Post-mortem examinations revealed very extensive bleeding and the appearance of congested and edematous tissue. The lymph nodes, spleen, liver and kidneys exhibited pronounced random focal necrosis and loss of cells in the follicles of the spleen and lymphoid tissue. Pigs have also revealed acute orchitis with massive neutrophilic infiltrates and macrophages in intertubular connective tissues. of meningitis and focal hemorrhages were observed in the brain and spinal cord. It seems that the home came from the spread east of the PPA, from Benin, neighboring state where the PPP had declared the previous year (1997)
Heavy metal contamination of clarias gariepinus from a lake and fish farm in Ibadan, Nigeria
(Ibadan Biomedical Communications Group, 2004) Olaifa, F. E.; Olaifa, A. K.; Adelaja, A. A.; Owolabi, A. G.
Adult Clarias gariepinus (African Catfish) were purchased from Eleiyele Lake and Zartech fish farm in Ibadan. Water samples were also collected in February (dry season) and June (rainy season), 2002. Gill, bone, intestine, muscle and water samples were analyzed for five metals: manganese, copper, zinc, iron, and chromium by atomic absorption spectroscopy (AAS) in two separate experiments. In each case, two tissues were compared with the levels of the metals in water viz: Gill, bone, and water; intestine, muscle and water. Generally, lower concentrations of the metals were recorded in water than fish tissues. Higher concentrations of zinc than recommended by the Federal Environmental Protection Agency were recorded in the fish during the dry season. Iron was the dominant metal in the muscle while Chromium was the least. Significant differences (p<0.05) were recorded in copper and zinc concentrations in the muscle, intestine and water during the dry and rainy seasons .In gill, bones and water, significant differences (p<0.05) were only recorded for the two stations for copper during the rainy season and only zinc was significantly different (p<0.05) in the dry season. It was concluded that though the heavy metals of interest were present in measurable quantities there were still within safe limits for consumption
Lethal and sub-lethal effects of copper to the African catfish (Clarias gariepinus) juveniles
(Ibadan Biomedical Communications Group, 2004) Olaifa, F. E.; Olaifa, A. K.; Onwude, T. E.
Lethal and sub-lethal effects of copper on Clarias gariepinus were studied using a 96-hour static bioassay. Copper (as copper chloride, CuCl2 . H2O) was used to prepare the stock solution from which five standard concentrations 0.0, 1.8, 3.2, 5.6, and 10.0 mg/L were prepared (coded A – E). 15 juvenile C. gariepinus fish having a mean weight and length 5.8g and 18 cm respectively were used. The 96-hour LC50 estimated using the logarithm method were 0.6, 0.71 and 0.7 mg/l for replicates 1, 2 and 3 respectively with mean as 0.67mg/l. Haematological changes were generally not significant (P> 0.05). Copper concentrations in bone and muscle-tissues were also determined. The mean copper concentration in bone ranged from 1.86 (treatment A) to 17.04 ppm (Treatment E) and muscle 1.29 (treatment A) to 55.5 ppm (treatment E). There were significant differences (p<0.05) in mortality among treatments
Splenic lymphoma in an adult local bitch-a case report
(2008) Oni, S. O.; Akinrinmade, J. F.; Ajadi, R. A.; Eyarefe, O.D.; Olaifa, A. K.
A four-year old local dog weighing 12kg was presented four days after signs of persistent anorexia and dullness were observed. Physical examination of the bitch revealed a circumscribed distension of the left lateral abdomen about 5cm caudal to the rib cage, which on palpation appeared firm, discrete and nodular but painless. X-rays views confirmed that the mass was intrasplenic and had a fat density. Blood and urine samples were analysed, the result of which showed proteinuria, bilirubinuria and neutrophilic leucocyosis. Exploratory laparotomy and spleenectomy were carried out. The extirpated spleen had pendunculated projection. The biopsy of the spleen revealed that the tumour is a lymphoma

Toxic stress of lead on clarias gariepinus (African catfish) fingerlings
(2003) Olaifa, F. E.; Olaifa, A. K.; Lewis, O. O.
The toxic stress of lead on fish was tested employing a 96-hour bioassay test. The experimental fish used were Clarias gariepinus fingerlings. Lead in the form of lead chloride was used to prepare the stock solution. The concentrations of lead used for the experiment were 0, 1.8, 3.2, and 5.6, and10.0mg/l. The lethal concentration (LC50) was estimated using the logarithmic method and was found to be 0.6, 0.58 and 0.62mg/l for replicates1, 2 and 3 respectively.
