In Nigeria, limited research has been conducted on Microplastics (MPs) in inland rivers, necessitating a comprehensive assessment to understand the extent of contamination. This study aimed to assess the abundance, distribution, and composition of MPs in fishes, sediment, and water from inland rivers across Nigeria's six geopolitical zones. Samples were collected from selected rivers in each geopolitical zone (Rivers Yauri, Benue, Argungu, Jamare, Ogun, Ethiope and Orashi). MPs were isolated using a combination of filtration, density separation, and visual identification. MPs abundance, distribution, shapes, colors, and chemical composition were determined using microscopy and Fourier-transform infrared spectroscopy. The study presents the first report of MPs in six in land rivers in Nigeria and found that MPs were present in all the fishes, sediments and river waters studied across all the rivers. The abundance and composition of MPs varied among the different sample types, with fibers being the most abundant shape in both water and fish samples. PET, PP, and PE were the most prevalent types of plastics found in fish samples, while PE/PA/Nylon, PVA, and PVC were predominant in water samples. PA/Nylon, PUR, PVC, and PET were the most common in sediment samples. Source analysis by Principal component analysis (PCA) and Hierarchical Cluster Analysis (HCA) indicated that the presence of MPs was mainly influenced by local anthropogenic activities. However, estimated daily intakes are generally low, indicating that daily consumption of the samples is not likely to be harmful. The widespread presence of MPs in inland rivers across Nigeria highlights the urgent need for effective waste management strategies and environmental conservation efforts to mitigate plastic pollution.

Objectives:
Youths can function as agents of change by disseminating essential information, but they are also
considered a vulnerable group in the COVID-19 pandemic. Literature on COVID-related knowledge, attitude, and anxiety has not focused comprehensively on youths. This study assesses the knowledge, attitudes, and anxiety level of youths in eastern Nigeria during the COVID-19 pandemic.
Methods:
We conducted a descriptive cross-sectional study using an online survey among young people between the ages of 18 and 35 years in southeastern Nigeria during the COVID-19 pandemic. We analyzed data using the Statistical Package for Social Science (SPSS) version 25 software. We used descriptive statistics, the Chi-square test, and bivariate and multivariate logistic regression analyses to measure the associations. A p-value of < 0.05 was considered statistically significant at a 95 percent confidence level.
Results:
We included 397 participants. Majority of the study participants (88%) had a high level of knowledge about COVID-19. Around 68% showed a good attitude toward COVID-19 prevention, overall low anxiety related to the COVID-19 pandemic was proportionally higher at 57.43%. Knowledge and educational level were statistically significantly associated with anxiety levels related to the COVID-19 pandemic.
Conclusion
The young adults had a good knowledge of the COVID-19 transmission and symptoms, positive attitude, and low anxiety levels. Those with higher educational levels had good knowledge and lower anxiety level. Public health and mental health experts can use this material to help reduce high levels of anxiety among the vulnerable population affected by the pandemic.
