Assessment of Water Quality from Hand Dug Wells in Kurmin Siddi, Kaduna State

Communication in Physical Sciences 2020, 5(2): 198-204 Authors: Ibrahim Usman, Williams N. Kaigama, Thankgod Daniel and Abu E. Benjamin Received 17 April 2020/Accepted 20 May 2020 After considering the necessity for portable water and hand dug wells as the common source of water, physicochemical and biological analysis was carried out on water samples collected from four hand-dug wells located within Kurmin Siddi settlement in Kaduna State, Nigeria. Mean values of the measured parameters were Turbidity (2.50±0.01  to  4.90±0.20  NTU) Hardness(61.99±0.02  to 83.70±0.01     mg/L), conductivity    (0.06±0.83  to 1.66±0.32µS/cm6),   pH(6.30±2.27   to  8.21±0.24)and total coliform count (9 to 26). The analysed parameters were compared with WHO (2002) requirements for drinking/portable water. Although all the measured parameters were within WHO standards, the total coliforms count is above the standard which indicate that the water is not suitable for drinking except it is treated

Phytoconstituents evaluation and antimicrobial efficacy of the crude flavonoids and saponins rootbark extracts of Terminalia avicennioides and Ficus polita

Introduction: Plant is a friend to man in survival as it gives him food, shelter and medicine beyond the ages of human civilization. This paper evaluates the phytochemical constituents and the antimicrobial activities undertaken on Terminalia avicennioides and Ficus polita. Methods: Phytochemical screening was conducted on the root extracts according to the standard procedures. The hole-in-plate disc diffusion technique was used to determine the antimicrobial activities of the crude saponins and crude flavonoids against the tested microorganisms used in this study. Results: The results revealed the presence of alkaloids flavonoids, saponins, sterols, phlobatannins and terpenoids. The antimicrobial activities presented as diameter of inhibition zones showed high activity value of 34.70±0.57 mm against Staphylococcus aureus and Pseudomonas aeruginosa at a concentration of 100 mg/mL and by crude flavonoids portion of T. avicennioides while the least activity was shown by crude saponins portion of F. polita at a concentration of 25 mg/mL with value of 9.67±0.58 mm against Shigella dysenteriae. The crude flavonoids inhibited the growth of Candida albicans at all concentrations while resisitances were found towards the crude saponins portion of both plants. Hence, flavonoids extractives from the two plants appeared to be more effective than the saponins against the tested microorganisms. Conclusion: These findings justify their potential use as drug-plant against bacterial-related infections in African traditional medical system and also suggest a possible insight for the isolation of bioactive chemotherapeutic agents from T. avicennioide

Medicinal plants used for the management of diabetes mellitus in Zaria, Kaduna state, Nigeria

Context: The knowledge of traditional uses of medicinal plants in the management of diabetes mellitus in Zaria is still intact with the traditional medicine practitioners. Aims: To collect, identify and document medicinal plants used traditionally for the management of diabetes mellitus in Zaria city. Methods: Open-ended informal interviews and general conversation were administered to twenty-two (22) traditional medicine practitioners (TMPs) and herb sellers. The data collected included the local names of plants, parts used, method of preparations and mode of administration. Results: Twenty-six (26) species of plants belonging to eighteen (18) families were identified. Herbal remedies were mostly prepared from freshly collected plants, while decoction was the main method of preparation. Leaves and stem bark formed the major parts of plants for herbal preparations. Conclusions: The study has documented different traditional practices used for the management of diabetes mellitus in the study area. Further studies should be conducted to evaluate the antidiabetic activity of plant species that have not yet been studied and to identify the bioactive compounds responsible for the antidiabetic activity as claimed by the traditional healers

Geoelectrical resistivity imaging of shallow oil sands in the Eastern Dahomey Basin (SW Nigeria): Implication for heavy oil exploration and production

The Eastern Dahomey Basin hosts an extensive reserve of oil sands, a significant portion of which is unexplored and located within the southwestern part of Nigeria. Here, we use detailed outcrop mapping and Electrical Resistivity Tomography (ERT) to investigate the physical and geological characteristics of the oil sands and surrounding lithological units within the Eastern Dahomey Basin in SW Nigeria. The oil sands in the studied outcrop belong to the Turonian to Maastrichtian sandstones of the Afowo Formation which is characterized by active bitumen seepage along the length of the outcrop. The ERT results reveal lateral and vertical variability of the overburden and oil sands units in the study area. The oil sands are characterised by two unique geoelectric anomalies. Each of these anomalies has higher resistivity values (>3713 Ωm) compared to the low resistivity values of the topsoil/laterite overburden (160–2790 Ωm) and the underlying clay dominated interval (160–1576 Ωm). Importantly, the oil sands have variable thicknesses of up to 20 m and are located at shallow depths (~1–5 m below ground level). Hence, the oil sands can be exploited using surface mining techniques. This study provides a detailed assessment into the application of a non-invasive geophysical techniques for characterising oil sands near an active seep system, with implications for drawing up exploitation strategies
