    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.
