- ItemA Follow-up Study on Lead Poisoning in Soil and Drinking Water Sources in Bagega Village in Zamfara State, Nigeria(Faculty of Basic and Applied Sciences, Kebbi State University, Kebbi, Nigera, 2024-12-31) Salami, Olalekan Oluwatoyosi; Aminu, Liman; Sawyerr, Henry OlawaleLead poisoning from artisanal small-scale gold mining has occurred in 38 villages in Zamfara State, Nigeria since 2010. Soils from only 8 of the affected villages had been remediated including those from the town used for this study. This study assesses the lead concentration in the soil and water media of the village. Soil samples were collected in the vicinity of the village as well as at the mining/processing site. Water samples were also collected from well, boreholes and the pond near the village. All samples were collected, preserved, and prepared for lead analysis using standard procedures. Atomic Absorption Spectrophotometer was used for lead content analysis. Lead in the mining/processing site (soil) was 9200 to 12500 mg/kg while that of the village soil was between 10.1 and 33.6 mg/kg. Lead content was detectable only in the well water (0.1 to 0.3 mg/kg) and in the pond (0.9 to 1.21 mg/kg). Although the values were below the US Environmental Protection Agency (EPA) guideline for soil lead, the level in water was elevated above the maximum allowable limit for drinking water. Better monitoring of children between 5 and 15 years of age for bioaccumulation was suggested to prevent future reoccurrence of the health impact of the affected children and young adults.
- ItemAssessment of drinking water quality in rural northern Nigeria: a case study of Diggi village in Kebbi State, Nigeria.(2024-06-30) Sawyerr, Henry Olawale; Iyanda, Yusuf Ayodeji; Salami, Olalekan Oluwatoyosi; Bagudu B. M.The United Nations Millennium Development Goals (MDGs) target, and recently, World Health Organizations’ SDG goal, was to achieve access to safe and affordable drinking water for all. An important strategy to achieve these goals was to obtain up-to-date information of water sources and their quality, especially the rural areas. This study assesses and provides such information on the typical sources and quality of drinking water available in a northern Nigeria rural community, most of which still lack infrastructure for effective treatment and distribution. Water samples from three wells and two boreholes were collected, analysed in-situ and in the laboratory for quality – physico-chemical, heavy metals and bacteriological parameters using appropriate methods. The pH was within acceptable limit (5.64 – 7.77) except in the well located at Illela. Although the conductivity (12.6-435.0 µs/cm), TDS (7.45-261 mg/l), alkalinity (10.0-12 mg/l) and chloride (1.9-45.9) values were lower than the recommended WHO ranges, the values could affect acceptability of the water. The well in Kofar Yamma recorded high lead values (0.09 mg/l) as well as chromium (0.08 mg/l) and arsenic (0.06 mg/l). The five water sources have very poor microbiologic quality with records of E. coli in all the samples. Boiling, chlorination and better hygiene practice was recommended for the village community.
- ItemEvaluation of biomedical waste in Kogi State University Teaching Hospital, Anyigba, Kogi State, Nigeria(Academic Journals, 2017-04-01) Sawyerr, Henry Olawale; Adeolu, Adedotun Timothy; Salami, Olalekan Oluwatoyosi; Adejoh, P. A.Adequate handling, efficient treatment and effective methods of biomedical waste play a vital role in the hospital infection control programme. Inadequate management of healthcare waste is a serious concern in many developing countries due to the risks posed to human health and environment. This study evaluates the biomedical waste generated at the Kogi State University Teaching Hospital, Anyigba. Seven wards were selected within the health facilities to determine the quantities of waste. The result showed that total waste generated in seven consecutive days was 19.89 kg/week. The average waste generated in seven wards was 2.8 kg/week and average waste generated per day was 0.4 kg/day. The quantity of waste increased as the number of patients and visitors increased. There were non-availability of bags in all the bins used for waste collection, storage and the bins were not colour coded, neither was there segregation of waste in the seven units. The study equally showed that the waste collected from the hospital are subjected to open burning which may affect the health of the workers, patients, visitors and the residents. There should be proper management of healthcare waste which can be improved through employment and retraining of staff, provision of colour coded bins and at least an incinerator for waste treatment before final disposal.
- ItemExploring University Undergraduate Students’ Knowledge and Attitudes towards Waste Management(Faculty of Education, Kwara State University, Malete, Nigeria, 2024-05-01) Salami, Olalekan Oluwatoyosi; Akanbi-Gada, Mariam A.; Iyanda, Yusuf Ayodeji; Ishola, Barakat AdebimpeAbstract Waste generation is inherent in various processes, posing environmental and health challenges. Although Kwara State University administration is committed to maintaining a clean environment, the level of awareness among students remains unclear. This study examines the knowledge and attitudes of university undergraduates toward waste management in kwara State university, Malete. Three hundred and thirty-two students participated, with 96% being under 28 years old. Results showed that 66% of respondents are aware of waste management, 51% have not taken courses on the subject, and 65% are unconcerned about waste-related issues, though 78% are aware that improper waste disposal poses a health risk. Seventy-one percent dropped garbage in a car or throw it out of the window, or just dumped it in a neighboring bush or drainage. The study concluded that the knowledge of students was at an intermediate level, but their attitude towards waste disposal was insufficient. It was recommended that relevant topics and practical experiences should be integrated into the undergraduate curriculum to enhance awareness and better attitude.
- ItemImpact of Dumpsites on the Quality of Soil and Groundwater in Satellite Towns of the Federal Capital Territory, Abuja, Nigeria(EHP PUBLISHING, 2017-06-01) Sawyerr, Henry Olawale; Adeolu, Adedotun Timothy; Afolabi, Abiodun Segun; Salami, Olalekan Oluwatoyosi; Badmos, Biola KazeemBackground: Urbanization, industrialization and changes in consumption patterns have compounded the problem of solid waste management in Nigeria. Poor waste management threatens the well-being and health of the local population, particularly those living adjacent to dumpsites. Objectives. An assessment of the impact of dumpsites in a satellite town of the Federal Capital Territory, Abuja, Nigeria was carried out to determine the level of biophysical/chemical parameters (pH, temperature, conductivity, nutrients (calcium and magnesium), heavy metals (lead, chromium, zinc), and microbial burden) on the quality of soil and groundwater and their impact on health and the environment. Methods. Soil and ground water samples were collected in four different dumpsites (Bwari, Gwagwalada, Kuje and Azhatta) with reference samples taken from the Federal Capital Territory, Abuja, and taken to the laboratory for biophysical/chemical analysis using standard methods. Results. The results were compared with the national and World Health Organization (WHO) standard limits for soil and water respectively. Except for zinc, the average concentrations for heavy metals in the soil samples were higher in all four dumpsites than the permissible levels. Soil and water parameters that exceed the standard limits pose significant health and environment risks to nearby residents. Conclusions. There is a need for raising the awareness of residents living close to dumpsites and those who use the well or nearby streams for domestic activities on the need to carry out adequate water treatment prior to its use.
- ItemPublic Perception and Adaptation to Climate Change in Moro Local Government, Kwara State, Nigeria(Department of Chemistry, Faculty of Science, University of Port Harcourt, Nigeria, 2025-01-01) Salami, Olalekan Oluwatoyosi; Rafiu, Fasilat Olajumoke; Akanbi-Gada, Mariam Abiola; Walliyyulahi, SofiyatThe objective of this paper was to evaluate the public perception and adaptation to climate change in Moro Local Government, Kwara State, Nigeria. A total of 60 questionnaires were administered across five settlements. Findings revealed that 45% of respondents had heard about climate change, though awareness levels varied, with Igbo Oreku showing the highest awareness (11.7%) and Okete the lowest (3.3%). About 90% of respondents acknowledged changes in rainfall patterns and temperature, which significantly had impact on their agricultural operations. Majority (75%) noted that the dry season had lengthened, and 78.3% observed a shift in planting times due to reduced rainfall. While only 40% acknowledged contributing to climate change through deforestation, 46.7% were willing to adopt adaptation strategies like reducing wood burning and participating in environmental campaigns. The study concludes that climate change adaptation must address local socioeconomic realities and be supported by targeted policies. Recommendations include increasing public awareness through local government-led education programs, promoting sustainable practices, and enhancing collaboration between local authorities, NGOs and communities.
- ItemSanitary Status and Compliance with the Standard Slaughter Practices in Karu Abattoir Abuja Municipal Area Council of the FCT, Nigeria(International Journal of Current Innovations in Advanced Research, 2019-02-01) Adeolu, Adedotun Timothy; Opasola, Olaniyi Afolabi; Salami, Olalekan Oluwatoyosi; Iyanda, Yusuf Ayodeji; Omenta, R. CAbstract: Background and Objective: The sanitary and hygiene conditions of abattoir are of public health concern because of its implications on the quality of meat being sold in the markets. In Nigeria, very few studies have provided a comprehensive assessment of the sanitary status in the abattoir premises. This study assessed the sanitary status and compliance with the slaughter practices in Karu Abattoir, Abuja Municipal Area Council of the Federal Capital Territory, Nigeria. Materials and methods: A descriptive cross-sectional study was conducted using semi-structured, interviewer-administered questionnaire and observational checklist adapted from Policy guidelines on market and abattoir sanitation by the Federal Ministry of Environment. Eighty (80) staff and workers of the abattoir were interviewed. Data obtained were analyzed using descriptive statistics. Results: More than half (53.7%) of the respondents reported that there is inadequate water supply facility and sourced their water from tap (64.6%) and dispose their waste water in the nearby stream. More than two-third (77.6%) of the abattoir workers reported that there are adequate veterinarians and other health officers and routine post mortem examination is adequate in the abattoir. The study showed that the abattoir lacks infrastructure and compliance with slaughter practices as basic requirements for a good abattoir as stipulated in the Policy Guidelines on Market and Abattoir Sanitation. Conclusion: The regulations on the operations of the slaughterhouse were below the standard requirements and that much was needed to be done to improve the system at the facility. There is an urgent need to enforce the minimum standards as stipulated in the policy guidelines.
- ItemThe Social Behaviour and Perceived Impact of Headphone Use across Selected Tertiary Institutions in Ilorin, Kwara State, Nigeria(Fountain University Journals, 2025-01-01) Salami, Olalekan Oluwatoyosi; Sani, Mohammed; Adiama, Yusuf Bolaji; Yusuf, MohammedBackground: Noise is regarded as sound which is generated as a byproduct of man-made or natural activities introduced directly or indirectly into the environment usually at levels above 80 dB. Daily exposure to noise in many occupations may impair hearing or reduce efficiency or both. Objectives: The aim of this study was to evaluate the headphone usage habits among adolescents in selected tertiary institutions in Ilorin and to examine the perceptions of adolescents regarding the impact of headphone use on their hearing health. Methodology: Data were collected from respondents across three universities in Kwara State using a descriptive survey research approach through a structured questionnaire to gather data from the students. The sample was drawn randomly in three key zones of the institutions – the Administration building area, the university bus park and the University library. Background sound level in these areas were also recorded. The collected data were analysed using descriptive statistics using SPSS 20 and the results were presented in frequencies and percentages to highlight trends across the study variables. Result: The findings reveal that most respondents (43.5%) prefer listening to music at medium volumes, with fun and relaxation (74.5%) being the primary motivations for headphone use. However, a significant portion experiences negative effects such as ear soreness, ringing in the ears, and distraction (62.0%). Despite these issues, many respondents show a lack of concern about potential hearing loss, highlighting a gap in awareness about the risks of excessive sound exposure. Additionally, the study finds that respondents often use headphones as part of their daily routine, with 43% occasionally removing their headphones to engage in social interactions. Conclusion: Several factors influence the reasons for headphone use among adolescents in these universities. Their behavior, perceived health implications, and experiences differ based on the duration and volume of exposure, as well as the background noise levels. The study recommended developing guidelines to promote mindful headphone use in shared spaces considering the growing incidence, especially among young persons. Parents, educators, and healthcare professionals should play active roles in raising awareness about safe listening habits.
