- ItemMrs(FUW Trends in Science & Technology Journal, 2024-03-28) Bilikisu SuleBisphenol-A is a plastic constituent, known as an endocrine disruptor, has become ubiquitous in the environment due to its presence in various products such as food and beverage packaging. This study investigated both acute and sub-lethal effects of Bisphenol-A on some haematological and biochemical indices of Clarias gariepinus fingerlings (mean weight, 8.0 ± 0.9g and Standard length, 5.0 ± 0.3cm), exposed to varying concentrations (0, 3, 5, 8, 10, 12mg/l) of bisphenol-A exposed for 96 hours and 60 days in plastic aquaria of 20L capacity, to determine both acute and sublethal toxicity respectively in static bioassay. Haematologically, the acute and sub-lethal exposures of C. gariepinus to BPA showed significant changes in levels of anaemia and haemodilution with packed cell volume values (19.67±0.33 and 30.00±0.58), while biochemical indices also showed significant changes in levels of induced hyperproteinaemia with total protein values (1.70±0.10 and 1.83±0.09) in the highest concentrations of both acute and sub lethal toxicity. Further research should be carried out to investigate the effects and bioaccumulation of this chemical on the muscle, brain and gonads of the fish.

- ItemPhytoremediation Potentials of Selected Plants in Crude Oil-Polluted Soils(Jewel Journal of Scientific Research, 2020-10-10) Olawepo, G. K1*, Ben-Uwabor, P. O.2, Ogunkunle, C. O.1, Danzaki, M. M.3, and Fatoba, P. O.Phytoextraction involves the absorption of contaminants by roots followed by translocation and accumulation in the aerial parts. It is mainly applied to metals (Cd, Ni, Cu, Zn, Pb) but can also be used for other elements (Se, As) and organic compounds. Experiments were carried out with 24 polyethylene pots each containing 7 kg of sandy loam soil mixed with 50 ml of crude oil. Twelve containers contained the crude oil-polluted soil while the remaining twelve containers contained the Control soil. Seeds of Amaranthus hybridus L., Tithonia diversifolia, Abelmoschus esculentus L. and Zea mays were sown in polyethylene containers containing 7 kg of contaminated or Control soil. The seeds were sown after two weeks of spiking the soil with crude oil. After two months, plants were harvested, separated into roots and shoots. Five heavy metals, namely Copper, Lead, Chromium, Cadmium and Nickel were evaluated. On the basis of the results obtained, the plants were classified as accumulators, hyperaccumulators, indicators or excluders. The results showed that Z. mays has the ability to accumulate Cu, stabilize Pb and Ni in crude oil-polluted soils. Z. mays is an excluder of Cr and Cd in crude oil-polluted soil. Z. mays showed suitability for Cr accumulation in Control soil with TF > 1 but less suitable for Pb extraction in Control soil with BCF, TF and BAF < 1. A. esculentus is suitable for phytoextraction of Cu, Cr and Pb, phytostablize Ni and Cd in Control soil. A. esculentus proved suitable for Cd phytoextraction in crude oil-polluted soil but less suitable for Ni extraction in crude oil-polluted soil. A. hybridus is an accumulator of Cu, Cd and Pb, stabilizer of Cr and Ni of crude oil-polluted and an excluder for Cr and Ni for Control soil. T. diversifolia was the most efficient in remediating Cu and Cd in crude oil-polluted soil. A. esculentus had the highest remediation factor in both crude oil-polluted (0.0475%) and Control soil (0.048%). A. esculentus was the most efficient at remediating Cd in crude oil-polluted soil, while T. diversifolia was the most efficient in the remediation of Cd in Control soil.
- ItemTOWARDS EFFECTIVE ORGANIZATION AND IMPLEMENTATION OF SCHOOL ORNAMENTAL HORTICULTURE PROGRAMME(Al-Hikmah Journal of Arts & Social Sciences Education, 2024-06) Alabi, John Omoniyi, Ben-Uwabor, Patience Olayinka, Iyapo, Kafayat AinaThis paper is a report of the study that examined the view of the Kwara State Educational Administrators and Secondary School Teachers towards the effective organization and implementation of the school ornamental horticulture programme. This study therefore intends to find out the views of the educational administrators and teachers as regards the services, organizational structure, and implementation of school ornamental horticulture programme. A descriptive survey method was employed in carrying out this study The instrument used was the scale of educational administrators and teachers “views about the establishment of ornamental horticulture programme, the instrument consists of 14 items of 30 questions clustered into five broad sections and one free response question administered on 200 respondents made up of Kwara State Ministry of Education officials and Secondary School Principals on one hand and teachers at Secondary Schools on the other hand. A five-point Likert scale technique was employed. The results showed a high level of awareness towards the organization and implementation of the programme, by the schoolteachers, administrators as well as the professional personnels and since it is a new programme or innovation, it needs the services of counseling unit for effective organization and implementation.
