Abstract Chronic exposure to sodium arsenite (SA), a common environmental pollutant, induces systemic toxicity characterized by hematological dysregulation and organ-specific inflammation, primarily through oxidative stress pathways. Vitamin E (α-tocopherol) is a potent lipid-soluble antioxidant with potential protective effects against such toxicity. This study investigated the ameliorative impact of Vitamin E on SA-induced hematological alterations and […]

Abstract This research explores the hydrometallurgical extraction of zinc from sphalerite (ZnS) using a salted-out alkaline leaching system composed of ammonia and ammonium sulphate, with particular focus on the kinetic mechanisms controlling dissolution. Conventional routes for zinc recovery, including pyrometallurgical and acidic hydrometallurgical processes, remain limited by their high energy requirements, elevated operating temperatures, and […]

Abstract Plant leaves are known to be rich in a wide range of bioactive compounds with diverse biological properties, making them valuable in drug discovery and development. This study investigated the bioactive constituents and sub-acute toxicity profile of Cola acuminata leaf extract. Fresh leaves were air-dried, ground into powder, and macerated in methanol for 72 […]

Abstract Phosphorus is critical to the growth and yield of plants, because it stimulates growth, initiates nodule formation as well as influences the efficiency of rhizobium-legume symbiosis.  Deficiency of phosphorus in plants is manifested in terms of stunted growth, reduced yield and delayed maturity. Application of organic or inorganic chemical fertilizers or combinations of both […]

Abstract Global interest has been in water, sanitation and hygiene practice due to its vital role in public health and environmental protection. This study evaluated the gaps in Water Quality, Sanitation and Health in Evbuotubu Community, Edo state, Nigeria. Physicochemical and bacteriological qualities of water samples were analyzed adopting standard analytical procedures and pour plate […]

Abstract This study assessed the diversity and abundance of fish species in the River Benue over an 18-month period (January 2020 to June 2021), spanning dry and wet seasons. Fish sampling was conducted monthly at three sites: Lau (Site A), Mayo-Ranewo (Site B), and Ibi (Site C), using gillnets of varying mesh sizes (60, 70, […]

Abstract This study presents insights into the screening, morphological and biochemical properties of some phosphate solubilizing microorganisms, which are organisms that can solubilize these fixed forms of phosphorus and make it available to plants.  A total of 27 Phosphate Solubilizing Microbial colonies were isolated on Pikovskaya agar medium, containing insoluble tricalcium phosphate (TCP) from agricultural […]

Abstract This study explores the potential of using Aspergillus niger for the sustainable bioleaching of zinc from municipal solid waste (MSW), offering an eco-friendly alternative to conventional extraction methods, which are often capital- and energy-intensive as well as environmentally hazardous. The physiochemical characterization of MSW was performed, with XRD analysis revealing the presence of quartz, […]

Abstract This study investigated the suitability of three organic planting media (sawdust, rice husk, and loamy soil) for growing lettuce (Lactuca sativa L.) in an open environment in Kaduna North Local Government Area, Kaduna State, Nigeria. A randomized complete block design with three treatments (media types) replicated five times was employed. The pH values of […]

Abstract This study covers the determination of inorganic contaminants which include lead (Pb), nickel (Ni), iron (Fe), copper (Cu) and zinc (Zn) in soil around tank farms in Oghareki community, Delta State. The soil samples were collected for a period of twelve months (April 2022 – March 2023) at distances of 100 meters to 1 […]
