Water quality index and correlation study for the assessment of water quality and its parameters in Etim Ekpo, Nigeria
Abstract Water bodies can be polluted by the addition of nutrients such as nitrates, phosphates, sulphates and chlorides through urbanization, agricultural, industrial and domestic activities. This study was aimed at determining the pollution status of EtimEkpo River, AkwaIbom State, Nigeria, during wet and dry seasons. Physicochemical parameters of water including, temperature, pH, dissolved oxygen (DO), […]
Comparative Evaluation of Phytochemical Constituents, Bitterness Characters and Essential Oil Contents of Extracts from Four Nigerian Plants as Potential Substitutes for Isomerized Hop Extract in Beer Brewing
Abstract Four selected Nigerian plants namely Azadirachta indica (neem), Garcinia kola (bitter cola), Gongronema latifolium (heckel) and Vernonia amygdalina (bitter leaf) as potential substitutes for hops in beer brewing were evaluated in terms of methanolic extracts. Phytochemical screening of the extracts was carried out using standard methods. The iso-alpha acid and essential oil contents of […]
Studies on the Removal of Petroleum Hydrocarbons (PHCs) from a Crude Oil Impacted Soil Amended with Cow Dung, Poultry Manure and NPK Fertilizer
Abstract The potential effects of animal-derived organic wastes and commercially available NPK fertilizer as nutrient supplements to biostimulate soil indigenous microorganisms for hydrocarbons degradation were investigated. 150 g each of soil samples were spiked with Bonny light crude oil (BLCO) (10 % w/w) and one week after contamination, about 30 g each, of the amendment […]
Phytochemical and in vitro antimicrobial efficacies of the crude flavonoids and saponins rootbark extract of Combretum glutinosum perrot. Ex. Dc.
Abstract The methanol rootbark extract of Combretum glutinosum was subjected to preliminary phytochemical screening and in vitro antimicrobial tests. The methanol rootbark extract revealed the presence of flavonoids, tannins saponins, alkaloid and cardiac glycosides using standard procedures. The antimicrobial activity of the plant extract was assayed by the agar plate disc diffusion and nutrient broth […]
Determination of percentage yield of oil extracted from watermelon seeds (A case study of Mainok, Kaga local government Borno state)
Abstract The extraction of oil from watermelon was successfully conducted using soxhlet apparatus, some chemical and physical analysis of the oil was carried out, and the percentage of the oil is 46. 11%. The proximate and physicio – chemical analysis of watermelon seeds were carried out. The result showed that the seeds had produced yellow […]
Determination of Concentration of Flouride in Some Boreholes (A case study of Monguno Local Government Area)
Abstract Fluoride is a natural mineral that protects and strengthened teeth against cavity. It is usually found in lower concentration in drinking water and foods. The concentration in seawater averages 1.3 (ppm). Fresh water supplies generally contain between 0.01-0.3ppm, whereas the ocean contains between 1.2 and 1.5ppm. In some locations, the freshwater contains dangerously high […]
Synthesis, Characteristics and Antiplasmodial studies of the deoxy and disulphide Derivatives of Dihydroartemisinin
Abstract Malaria parasite has developed resistance to the available and affordable drugs. The world health organization has recommended the use of artemisinin and artemisinin based combination therapy (ACT) for the treatment of chloroquine resistant uncomplicated malaria. The use of the artemisinins is challenged by short half life of the drugs due to the presence of […]
Comparative Analysis of Heavy Metals in Some Vegetables within Maiduguri Metropolis
Abstract Pollution is the undesirable changes in the physical, chemical or biological characteristics of air, water or land that can harmfully affect the health, survival or activities of human or other living organism. Soil is a dynamic habitat for an enormous variety of life-forms. It gives mechanical support to plants from which they extract nutrients. […]
