    Assessment of Heavy Metals Concentration in Swampy Agricultural Soil of Nasarawa West, Nigeria
    (Department of Physics, Nasarawa State University Keffi, 2019-01-18) Abdullahi, Abbas Auta; Ibrahim, Umar; Abubakar, Abdullahi Mundi; Mustapha, Mohammed Idris; Sarki, Usman Musa
    Aim: This research was carried out to investigate the concentration of heavy metals in swampy agricultural soil of Nasarawa west, Nigeria. Study Design: To compare the swampy soil heavy metal concentrations with regulatory standard or allowable values by the World Health Organization (WHO) and other National and International standards. Place and Duration of Study: Department of Physics, Nasarawa State University Keffi between January, 2018 and October, 2018. Methodology: Ten soil samples from each of thefive sampling locations (Karu, Keffi, Kokona, Nasarawa, and Toto) were randomly collected. A total of fifty (50) soil sampleswere collected within the period of one week. The collected samples were stored in polyethylene bag and labeled properly and taken to the Center for Energy Research and Development (CERD) at Obafemi Awolowo University Ile- ife Osun State, Nigeria. At CERD, elemental analysis was carried out for the fifty sample using X- ray fluorescent spectrometry analyzer. Results: The range of mean concentration of Zn, As, Cd, Pb, Fe, Ni, and Cu (in KR, KF, KK, NS, and TT locations) are 243.60- 502.80 mg/kg, 7.40- 37.00mg/kg, 260.90- 524.50 mg/kg, 167.80 336.60 mg/kg, 20222.90- 58170.50 mg/kg, 342.20- 555.10 mg/kg, and 266.60- 515.90 mg/kg respectively. The average mean of all the sample locations are found to be higher than the WHO allowable concentration limits of As (20 mg/kg), Pb (100 mg/kg), Cd (3 mg/kg), Zn (300 mg/kg), Fe (n.a), Ni (50 mg/kg), and Cu (100 mg/kg)respectively. There is high concentration Zn, As, Cd, Pb, Fe, Ni, and Cu in the swampy soil. Conclusion: The results indicates that the swampy agricultural soils of Nasarawa west (Karu, Keffi, Kokona, Nasarawa, and Toto) are contaminated with toxic metals (Zn, As, Cd, Pb, Fe, Ni, and Cu).

    Assessment of the Knowledge and Attitude to Radiation Safety Standards of the Radiological Staff in Damaturu, Yobe State, Nigeria
    (Department of Physics, Nasarawa State University Keffi, 2020-06-09) Dauda, Samson Yusuf; Umar, Ibrahim; Bukar, Idris Abba; Mustapha, Mohammed Idris
    Radiation protection and safety has been a major concern of many national and international bodies because of the potential hazardous effects associated with ionizing radiation if not properly controlled. However, no much research has been done on the compliance of Radiographers to radiation safety standards in Nigeria. In this study, we access and evaluate the level of compliance of the radiological staff in Damaturu, Yobe State using a self-structured questionnaire. The simple random sampling technique was used to collect 25 valid responses from radiographers, radiologist, technicians and other staff, corresponding to 92.86% response rate. Results show that even though the radiographers show high compliance rate to radiation safety standards, majority of the workers do not have thyroid shields and monitoring devices and since the total number of exposures given during radiography is usually not recorded, it means they are over exposing themselves as well as the patients to radiation which is not a good safety measure. However, hospital management should focus attention on providing continuous professional development programs and quality assurance programs so as to maintain good processing of X-ray films for good quality radiographs as this will reduce repeated exposures. Provision of monitoring devices and thyroid shields are of great importance.

    Health Risk Assessment of Heavy Metals in Swampy Agricultural Soils in Nasarawa West, Nigeria
    (Department of Physics, Nasarawa State University Keffi, 2018-12-01) Ibrahim, Umar; Abubakar, Aisha Kana; Abdullahi, Abbas Auta; Mustapha, Mohammed Idris; Abdullahi, Mundi Abubakar
    In this study, the health risk caused by heavy metals in swampy agricultural soil of Nasarawa west was assessed. A total of 50 soil samples from five local government of Nasarawa west (10 from each) were collected and analyzed for Asernic (As), Lead (Pb), Cadmium (Cd), Nikel (Ni) and Zinc (Zn) present in the samples using XRF Spectrometry at Center for Energy Research and Development (CERD) in Obafemi Awolowo University, Ile lfe. Osun State, Nigeria. Measured concentrations of these heavy metals were then used to calculate the health risk for adults and children. The result show that the concentrations are in the order of Ni> Cd> Zn>Pb>As which are all below the permissible level except for As which appear to be higher than the permissible levels. The Hazard Index (HI) of all the pathways for adults and children were found to be 1.55 and 12.19 respectively. These values are greater than 1 which is the tolerance level for both adults and children. These makes non- carcinogenic effects significant to the adult’s population and pose serious non- carcinogenic effect on children in those areas. The carcinogenic risk values were found to be both higher than acceptable values. This implies that there is a probability that 1 adult in about 10,000 may be affected.
