(Asian Journal of Advanced Research and Reports, 2024-10-17) Solomon Olayinka Adewoye; Yusuf Adiama; Opasola Olaniyi Afolabi; Adebayo, Buliyaminu Amoo
The effective implementation of International Health Regulations (IHR) at points of entry is crucial for safeguarding public health and preventing the spread of infectious diseases across borders. However, the process faces significant constraints that hinder its success. This study aims to assess the key constraints impeding the successful implementation of IHR at various points of entry in Lagos, Nigeria, specifically at the Murtala Muhammed International Airport, Seme Land Border, and the Lagos Sea Port. A descriptive correlational research design was employed, utilizing a structured questionnaire administered to customs officials, immigration officers, health professionals, and other relevant stakeholders. The study revealed that factors such as inadequate knowledge among personnel, insufficient resources, and limited interagency collaboration are major barriers to effective IHR implementation. The analysis showed a significant relationship between years of experience and knowledge of IHR implementation, highlighting the importance of continuous training and capacity building. Additionally, challenges related to resource availability, including insufficient equipment, lack of personnel, and inadequate facilities, were found to critically affect the implementation process. Despite the majority of respondents indicating adequate physical facilities, a substantial funding gap was identified, underscoring the need for improved financial support to enhance IHR enforcement. The study recommends that addressing these constraints through targeted interventions, including enhanced training programs, better resource allocation, and stronger interagency coordination, is essential for strengthening health security at points of entry in Lagos. The study emphasizes the critical role of sustained investment in infrastructure, training, and interagency collaboration to achieve the full potential of IHR in protecting public health.

(Innovative Journal of Medical Sciences, 2022-03-02) Habeeb Modupe Lateefat; Sawyerr Olawale Henry; Opasola Afolabi Olaniyi
The rise in contamination of raw foods by heavy metals has become an unavoidable problem nowadays. The episodes of accumulation of heavy metals in the biotic environment result from rapid increase in industrial activities, advancement in agricultural methods, or the activities of humans in the urban settings. These activities have prompted metal distribution in the environment and, subsequently, resulting to impairment in health of the populace by the ingestion of food contaminated by harmful metals components. The aim of this study was to assess the heavy metals concentrations and characterize the heavy metals found in raw food samples collected from selected standard hotels in Kaduna State and compare with the Food Agriculture and Organization (FAO)/World Health Organization (WHO) guidelines so as to assess the potential health hazard. Twenty samples of rice and nine samples beans were obtained from 20 hotels within three-, four-, and five-star ratings with their purchase sources coded from hotel 1 to 20 for confidentiality. The powdered samples were digested with nitric acid. Extract from the digest was analyzed for Copper (Cu), Lead (Pb), and Cadmium (Cd) using Buck Scientific AAS. The results of this research indicated levels of HMs were within safe limit, when compared with FAO/WHO standard and concentrations are significantly low, as the heavy metals are the same across the samples at P-value set at 0.05. The results of this study indicated presence of the heavy metals (Copper, Cadmium, and Lead) in the samples but they were at safe levels when compared with the WHO standard. Despite these, one should not neglect the fact that the two metals (Cd and Pb) accumulate in the body over time because of consumption frequency of beans and rice. Bioaccumulation rate can pose serious health risk to consumers. Implementation of hazard analysis critical control point for routine assessment of heavy metals in food products to help eliminate of not exceed global standard for food safety should be practice.

(Pure Earth: Journal of Health and Pollution, 2019-03-22) Opasola, O.A, Adeolu, A.T, Iyanda, A.Y, Adewoye, S.O and Olawale, S.A
Background. Harmful wastes and other dangerous industrial by-products constitute major sources of environmental pollutants in Nigeria. Industrial pollutants discharged into the environment contain organic and inorganic pollutants in dissolved, suspended and insoluble forms. Fishes are known for their innate potential to bioaccumulate heavy metals in their muscles and various organs. Objectives. The present study aimed to assess the bioaccumulation status of heavy metals in selected organs and tissues of African catfish in Asa River, Ilorin, Kwara State, Nigeria. Methods. Three sampling points (A (upstream), B (point of discharge) and C (downstream)) were selected in relation to industrial effluents that enter the river. African catfish were randomly harvested from each site using fishing nets at the three sampling points. The samples were digested and subjected to atomic absorption spectrophotometric analysis. Statistical analysis of data was carried out using the Statistical Package for the Social Sciences (SPSS) version 20 and two-way analysis of variance (ANOVA) to compare data among sites and organs. Results. The present study found that the bioaccumulation level of heavy metals in selected organs and tissues of African catfish in Asa River, Ilorin, Kwara State, Nigeria was very high and the level of accumulation of heavy metals increased downstream. Accumulations were much higher during the dry season (especially in the month of February) and relatively low during the peak of the rainy season. Conclusions. Heavy metals at elevated levels in the aquatic environment can accumulate in fish tissues and organ, and therefore fish from the Asa River are not fit for human consumption.

(SEAHI PUBLICATIONS: International Journal of Innovative Biochemistry & Microbiology Research, 2017-12-23) Opasola O.A; Iyanda Y.A.; Sawyerr H.O; Adewoye S.O; AbdulRahman H; Dauda K. A. and Onifade I. A.
The rise of multiple resistance bacteria among the pathogenic bacterial community is becoming a serious threat to public health most especially those contaminating environmental surfaces like the surface of Automated Teller Machine (ATM). This study was carried out in other to evaluate the prevalence of microbial contamination with its antibiotic resistance on automated teller machine and to elucidate its implications on the users of ATM. Twelve samples were collected from different ATM centers including the ATM at Kwara State General Hospital, Al-Hiqma University and the only ATM located around the busy part of Garin Alimi along Asa dam, Ilorin. Based on standard microbiological methods, the distribution of these organisms shows that 28.6% of the isolated organisms were Pseudomonas aeruginosa, 11.9% were Proteus vulgaris, 38.1% were Morganella morgani, 19.0% were Klebsiella edwardsii, and 2.4% were Proteus mirabilis. Antibiotic susceptibility test revealed that all the isolated organisms (100%) were resistance to septrin and 80% of all the organisms were resistance to chloramphenicol, amoxacillin, augmentin and Pefloxacin. From this study, it can be concluded that there is heavy bacterial contamination of ATM surfaces with bacteria that are resistant to commonly used antibiotics in human medicine, therefore, there is urgent need for frequent disinfection of ATM machines and its accessories along with periodical microbiological surveillance.

(American Journal of Environment Studies, 2024) Kolawole Adebayo; Modupe Lateefat; Maryam Abimbola; Abigeal Abosede; Olaniyi Afolabi; Modupe Olabisi
Purpose: The research aimed to investigate the challenges associated with waste disposal and management in Eyenkorin, a peri-urban neighborhood in Kwara State. Materials and Methods: The study adopted cross-section survey research. The study involved sampling 250 respondents within Eyenkorin using a questionnaire as the primary data collection instrument. Demographic information such as gender, marital status, and age was recorded, alongside data on waste storage methods, disposal practices, frequency of disposal, and average weekly waste generation. The data was presented in tables. Findings: The findings revealed that a majority of the respondents were male, married, and aged between 41-60 years. Plastic baskets were identified as the primary means of waste storage, with burning being the preferred method of waste disposal. Waste was disposed of every fortnight, with an average weekly waste generation of less than 5 kg. The implications of improper waste disposal included the creation of breeding spaces for germs and pollution. Furthermore, the study identified nonchalance by residents, poor policy frameworks, and a lack of technical know-how as the major challenges of waste management in Eyenkorin. Implications to Theory, Practice and Policy: In conclusion, the research highlighted the inadequacy of waste management services and facilities in Eyenkorin, despite its status as a fast-growing peri-urban area. The increasing physical development of the neighborhood necessitates a proportional enhancement of waste management infrastructure. This suggests a disparity between current waste management practices and the evolving needs of the community, underscoring the urgency for policy interventions and technical support to improve waste management in peri-urban regions like Eyenkorin.

(Malaysian Journal of Society and Space, 2023) Bamiji Michael Adeleye; Ayobami Abayomi Popoola; Zitta Nanpon; Kolawole Adebayo Shittu; Funke Jiyah; Hangwelani Magidimisha-Chipungu
The conversion of vegetation land cover contributes to the retention of solar radiation in the environment, resulting in the formation of the urban heat island. This study analyses the distribution pattern of urban heat island in the traditional core of Ibadan amidst the rapid urbanization experienced. The remote sensing tool was used to analyse the trend of land surface temperature, normalized difference built-up index, and normalized difference vegetation index for the traditional Ibadan's core between the year 2000 and the year 2020. This reveals that increasing built-up areas will continue to strengthen the effects of urban heat island in the traditional core of Ibadan, while vegetated land covers will weaken the effects of urban heat island. This is because anthropogenic activities resulting from rapid urbanisation has adversely altered the natural landscape in the traditional core of Ibadan. This alteration manifests in converting vegetation land covers into physical developments and other impervious surfaces by the increasing urban population. Thus, increasing the land surface temperature. The maximum average land surface temperature of 35.34℃, 36.62℃ and 31.86℃ were record for the years 2000, 2013 and 2020 respectively. This study further recommends that urban greening and proper urban planning should be encouraged in the traditional core of Ibadan.
Comparative Assessment of Seasonal Variations in the Quality of Surface Water and Its Associated Health Hazards in Gold Mining Areas of Osun State, South-West Nigeria
(LIDSEN Publishing Inc., 2023-01-23) Awogbami Stephen Olalekan; Solomon Olayinka Adewoye; Sawyerr Olawale Henry; Morufu Olalekan Raimi
Industrial and urban development are contributing to an increase in global environmental degradation. Therefore, the release of heavy metals from mining-related operations into surface water is harmful to human health. But as anthropogenic influences on the environment grow, surface water characteristics are also alter, impacting aquatic creatures. In order to analyze the acceptability of the surface water in the gold mining area for drinking and irrigation uses, different quality water assessment methodologies were incorporated in this research. In light of this, the purpose of the current study is to comprehend how the hydrogeochemistry and appropriateness of surface water for drinking and irrigation vary every month. The study employed standardized analytical techniques. According to APHA recommendations, all sampling, conservation, transportation, and analysis were completed (2012). All collected samples were transported to the study lab while being kept in an icebox to prevent the degradation of the organic components. As a result, the study is focused on the contamination level in the surface water for a year. Overall, the study highlights important pollutants impacting surface water quality as it passes through Osun State's gold mining regions. Finally, it has been determined that the following criteria are crucial for the stretch of this research season: DO, Hardness, Turbidity, Chloride, Potassium, Nitrate, Lead, TSS, Cadmium, Chromium, Sulphate, Manganese, Mercury, and Arsenic. Most of the physicochemical variables examined in this study fell within their corresponding standard limits. Based on the results of this study, the appropriate constituted authority is encouraged to continuously monitor and assess surface water quality suitability for drinking, domestic, and irrigation purposes by keeping track of the effects of water contaminants and detecting any changes in the water quality. To safeguard and maintain groundwater quality and public health, it is advised that appropriate regulatory policies and water treatment procedures be employed in the area. Additionally, it is proposed that when enhancing water quality and investigating the sustainable use of water resources, surface water pollution should be taken into consideration.
Concentrations of Pesticides Residues in Grain Sold at Selected Markets of Southwest Nigeria
(Visagaa Publishing House, 2023-07-29) Modupe Abeke Oshatunberu; Adebayo Oladimeji; Sawyerr Olawale Henry; Opasola Afolabi Olaniyan; Morufu Olalekan Raimi
ABSTRACT: The objective of this work is to determine the concentration of the identified pesticide in grains commonly used by farmers, and which are available directly from the open markets in the Nigerian market. Pesticide residues were quantified through a multiresidue method using a varian 3800/4000 Gas Chromatograph Mass Spectrometer (GC/MS). The simultaneous measurement of four classes of pesticides by gas chromatography-mass spectrometry (GC/MS) approach using sample preparation on QuEChERS-citrate, was developed and validated. The results frequently showed high specific contamination, which makes sense given the target market and dietary diversity in the area. This study found that grains purchased from particular markets in southwest Nigeria contained numerous pesticide residues. The MRLs set by the EU or FAO/WHO or both were surpassed by 17 out of the total 27 pesticides reported in this work in at least one grain, despite the fact that there were no published codex MRLs for some pesticide residues in some grains. These residues were classified among the four pesticides classes: carbamates, organophosphates, organochlorines, and pyrethroids. In actuality, 90% of the mainly banned organochlorine pesticides exceeded MRLs. Thus, this study revealed higher concentration levels of organo-chloride pesticides and organo-phosphate pesticides in grain samples drawn from selected markets in southwest Nigeria. Consumers seeking high-quality food in Nigeria should take note of these facts. Notwithstanding, the small number of samples with detectable residues suggests that there is a necessity to increase monitoring of pesticides in grains, educating farmers, and raising their awareness of the dangers associated with the unauthorized use of pesticides that are only allowed in agriculture and can damage the reputation of the sector as a whole.

(Conscientia Beam, 2022-04-28) Edet OTTO; Henry SAWYERR; Olaniyi OPASOLA
The aim of this study was to evaluate the Ecological Footprint (EF) for Environmental Sustainability in Ijebu Ode. The study adopted a descriptive cross-sectional study design and the objective was to assess the average EF of Ijebu Ode. Both primary and secondary data were employed, and the primary data for this study was collected from four hundred (400) systemically sampled households through structured questionnaires, and analysed descriptively using the Statistical Package for Social Sciences (version 20.0). The findings revealed the average ecological footprint of the Ijebu Ode to be 0.3gha per capita, with the footprint of water as the highest contributor to the EF, with 0.9gha (86.5%) of the total footprint. Thus, the study concluded that, the average EF of Ijebu Ode is 0.3 gha and therefore sustainable. However, it was recommended that, sustainable consumption must be encouraged, implemented and demonstrated to sustain the current EF of Ijebu Ode and public campaigns should be encouraged and implemented adequately in light of increasing awareness of the adverse environmental impacts of unsustainable consumption.
Ecological Footprint of Energy Consumption in Ijebu Ode, Nigeria
(Journal of Technology Innovations and Energy, 2023-03-20) Sawyerr H , Opasola O. A, Otto, E, and Nsikak A.
Notwithstanding overwhelming evidence that shows how unsustainable energy consumption contributes to our already rising ecological footprint (EF), the situation is mostly unchanged worldwide, especially in developing countries with poor equipment for efficient energy generation, with a growing threat of global warming due to unsustainable energy consumption and its disastrous environmental effects. Therefore, this study sought to analyze the ecological footprint of energy consumption in Ijebu Ode. A descriptive cross-sectional method was employed, and primary data were sourced from systemically sampled 400 households using structured questionnaires, analyzed descriptively using Microsoft Excel, and inferentially using the ecological footprint mathematical model. Findings revealed the overall EF of energy consumption in Ijebu Ode at 0.07 gha/capita, constituting about 6.7% of the city EF share, with electricity having the major share (0.04 gha; 51.9%), followed by gas with a footprint of 0.02 gha (26%). The lowest of the energy footprints were kerosine, charcoal, and firewood, with 0.003 gha (3.9%), 0.002 gha (2.6%), and 0.001 gha (1.3%), respectively. Thus, we conclude that Ijebu Ode has sustainable energy consumption, and therefore calls for practical policy directives aimed at improving our natural gas distribution potential to facilitate household availability and affordability in light of our reputation as the highest natural gas reserve holder in Africa.
Ecological Footprint of Food Consumption in Ijebu Ode, Nigeria
(Asian Journal of Basic Science & Research, 2022-08-14) Edet Otto; Henry Sawyerr; Olaniyi Opasola; Babatunde Adiama
A recent study establishes that since 1970, there has been an ecological gap between human needs and the planet's resources, with annual resource demand exceeding the bio-productivity of the planet. Specifically, humanity utilises equivalent of 1.75 earths to produce the ecological resources used, with half of this attributable to food consumption. The present work therefore seeks to provide an empirically-based insight into the environmental sustainability of the EF of food consumption in Ijebu Ode. A descriptive cross-sectional approach was used, and primary data were collected from 400 systemically sampled households via structured questionnaires and analysed descriptively using Microsoft Excel and inferentially using mathematical models for calculating ecological footprints. Findings revealed that the household EF of food consumption in Ijebu Ode is 0.05gha per capita, with the footprint of cereal consumption (0.17gha; 37%) taking the major share, followed by meat with a footprint of 0.11gha (23.9%). As a result, it was concluded that Ijebu Ode has sustainable food consumption, which is necessary for its environmental sustainability. However, the sustenance of the former requires creating awareness of the need for sustainable consumption and prioritisation of integrated and population-wide policies and food intervention initiatives to encourage attitudinal change in favour of sustainable food consumption while fostering sustainable food production strategies amidst current environmental realities.
