ASSESSMENT OF MICROPLASTICS CONCENTRATION IN SOME SELECTED FISHES AND WATER FROM CHALLAWA RESERVOIR, KANO

ABSTRACTS Microplastic pollution is a growing environmental concern, especially in freshwater ecosystems. This study aimed to assess the concentration of microplastics in selected fish species (Catfish, Tilapia, and Mackerel) and water samples from the Challawa Reservoir using Fourier Transform Infrared Spectroscopy (FTIR). The FTIR analysis revealed the presence of distinct absorption peaks corresponding to functional groups such as O-H, C=C, C≡C, C-O, and C=N, indicating the presence of various chemical groups including oxygen, nitrogen, and aliphatic compounds. The predominant polymer identified in both fish and water samples was polystyrene, suggesting contamination from industrial or domestic sources. Microplastic particles were consistently detected across all fish samples, highlighting potential bioaccumulation. Water samples from multiple weeks also showed a recurrent presence of microplastics, reinforcing the persistent nature of plastic pollution in the reservoir. These findings indicate a potential risk to aquatic organisms and human health through the food chain. The study emphasizes the need for effective pollution control strategies and further research on microplastic impacts in freshwater ecosystems
