    Emissions of CO and SO2 from solvent extraction treatment of used lubricant
    (4th International Conference on Science and Sustainable Development, 2021) Oladimeji, Temitayo E.; Sonibare, Jacob A.; Omoleye, James A.; Emetere, Moses, E.; Odunlami, Olayemi, A.
    Emissions fromused lubricant could have adverse effect on man and its environment due to the presence of degraded additives and contaminants. Different treatment methodshas been developed with few check on its pollution aspect. This study investigated the emissions of two major criteria pollutants - carbon monoxide (CO) and sulphur dioxide (SO2) from the solvent extraction treatment of used lubricant. CO was found to be the highest emitting pollutant with mean emission concentration of 85.85 mg/m3 which has exceeded the set NAQS standard while SO2 falls within the standard limit. Therefore,there is a great need to give attention to the control of CO emissions around the treatment plant. However, CO emission can be controlled by employing a CO converter to convert the poisonous gas to a less poisonous gas or substituting the existing process in solvent extraction with a more environmentally friendly one.

    From origin to oversight: properties, impacts and management of heavy metals
    (Discover Applied Sciences, 2025) Oladimeji, Temitayo E.; Oyedemi, Melody O.; Odunfa, Moradeyo K.; Agboola, Oluranti; Adeoye, John B.; Oke, Michael A.; Akindele, Olubukola O.
    Heavy metals, derived from both natural processes (e.g., rock weathering) and anthropogenic activities (e.g., industrial emissions, agricultural runoff ), pose significant environmental and health risks due to their persistence and bioaccumulation in ecosystems. This review emphasizes the need for an in-depth examination of heavy metals, their sources, properties, toxicity, and management. The document also evaluates regulatory frameworks aimed at managing heavy metal contamination and highlights the need for innovative detection and regulation. It underscores the importance of future research and policy advancements to strengthen remediation efforts, safeguard public health, and promote sustainable environmental practices
