VISUAL IDENTIFICATION OF MICROPLASTIC CONTAMINATION IN COMMON BLEAK (Alburnus alburnus, L. 1758) FROM GRUŽA LAKE

Microplastics (MPs) in freshwater ecosystems pose significant environmental risks, particularly to fish populations. This study examines the gastrointestinal (GI) tract contents of fish, revealing a predominance of blue fibers, likely originating from textiles and fishing activities. After visual detection, digestion of residual biological material is needed for precise analysis. Identifying MPs requires chemical techniques like FTIR and Raman spectroscopy. Blood traces in fish intestines suggest potential physiological impacts. As lakes act as pollution sinks, understanding MPs sources is crucial for mitigating risks to aquatic ecosystems and ensuring environmental sustainability.
