    ECOTOXICOLOGICAL IMPACT OF PLASTIC ON SELECTED AQUATIC AND TERRESTRIAL HABITATS OF MALETE MORO LOCAL GOVERNMENT AREA OF KWARA NORTH CENTRAL, NIGERIA
    (FUDMA Journal of Sciences, 2024-02-01) Amubieya, Omolara Faith
    Plastic pollution is now a major environmental issue that has a significant impact on ecosystems all around the world. The aim of this research was to examine the ecotoxicological effects of plastic pollution on the aquatic water bodies and terrestrial habitats, in urban centers and waste disposal sites of Malete Community, Kwara State, Nigeria. Plastic samples were collected from three sampling points with the following coordinates, (Latitude 8° 71' 8" and longitude 4° 46' 8"), (Latitude 80 70' 8" Longitude 40 46' 8"), and (Latitude 8° 70' 8" and longitude 4° 46' 8") and they were tagged samples 1, 2 and 3 respectively, this was done as a representative of aquatic and terrestrial ecosystems. Gas Chromatography-Mass Spectrometry (GC-MS) analysis as well as chemical characterization of the plastic samples were carried out using standard procedures and methodologies. Interestingly, sample 1 has high levels of the following compounds, benzene (8.3%) ethylbenzene (22.6, %) and styrene (45.2%), known to have harmful impacts on aquatic life. The presence of 1-Octene (18.9%) and 1-Nonene (22.6%) in Sample 2 indicated the possibility of biomagnification through food chain. The presence of ethyl terephthalate (25.9%), and ethylene glycol (19.3%), which are compounds associated with aquatic toxicity, was evident in Sample 3. This study highlights the widespread ecotoxicological impact of plastic pollution in the aquatic and terrestrial ecosystems of Malete Community, Kwara State. The presence of hazardous compounds in the plastic samples suggests significant risks to environmental health.

    Influence of Biochar on Lead –Induced Oxidative Damage and AntiOxidative Defense Mechanisms on the Leaf of Solanum lycopersicum (L.) (Tomato)
    (Jewel Journal of Scientific Research (JJSR), 2024-06-23) Amubieya, Omolara Faith
    This study examined the impact of biochar derived from kolanut pods on the growth of Solanum lycopersicum (tomato) and its ability to mitigate oxidative stress caused by lead (Pb) toxicity. A pot experiment was conducted in artificially Pb-contaminated soil, utilizing various levels of biochar application (1%, and 3% w/w). Tomato seedlings were cultivated under four treatment conditions for 74 days; control, soil spiked with 250 mg Pb/kg, soil spiked with 250 mg Pb /kg and treated with 1% biochar, and soil spiked with 250 mg Pb and treated with 3% biochar. Growth parameters, which include the plant height, leaf number, stem girth, leaf area, number of petiole and petiole length were monitored. The findings indicated heightened oxidative stress in plants grown in soil solely spiked with Pb. Application of 1% biochar enhanced plant growth, whereas a higher dose (3%) hindered growth. Both 1% and 3% biochar treatments reduced oxidative stress and improved antioxidant activities compared to the control and Pb-contaminated soil without biochar amendment. Consequently, the application of biochar to soil contaminated with Pb shows promise in mitigating the hazards posed by lead (Pb) toxicity in plant.

    Plastic Bag Usage, Inappropriate Disposal and Its Environmental Impacts in Ilorin Kwara State, Nigeria
    (Department of Chemistry, University of Port Harcourt, Nigeria, 2024-12-01) Akanbi-Gada, Mariam Abiola; Amubieya, Omolara Faith; Salami, Olalekan Oluwatoyosi; Sule, B. T.; Olabamiji, S. T; Oyewopo, A. O.
    Plastic bag usage and inappropriate disposal have become serious environmental issues, especially in developing nations with sometimes insufficient waste management infrastructure. Hence, the objective of this paper is to survey the plastic bag usage, inappropriate disposal and its environmental impacts in Ilorin, Kwara state, Nigeria by collecting primary data with 100 an online questionnaire. The results were then analyzed and displayed in graphical formats, such as pie charts. According to the poll, 76% of participants said they preferred using plastic bags, and 69% said they used them occasionally. Burning (45%) and open dumping (47%), two disposal techniques that greatly increase environmental contamination, were used. Additionally, 92% of respondents said they were aware of the negative environmental effects of disposing of plastic bags. The findings show that Ilorin has a significant reliance on plastic bags, and that inadequate waste management methods are causing environmental deterioration. The study discovered that although most people are aware of the harm plastic trash does to the ecosystem, inappropriate disposal practices are nevertheless common.
