Abstract :Microplastic insert ignore into journalissuearticles values(MP); ingestion by fish can not only impact the environment but also human health. This study determines the abundance and composition insert ignore into journalissuearticles values(polymer, shape, size); of MPs ingested by gray mullet insert ignore into journalissuearticles values(Mugil cephalus);. A total of 30 specimens were purchased from local fish market collected from Lake Cernek located in Kızılırmak Delta, Türkiye by local fishermen. The digestive tracts of the fish were removed and digested with hydrogen peroxide insert ignore into journalissuearticles values(H2O2); to extract microplastics. The share of the contaminated fish with microplastics was 90%. The average microplastic abundance by individual and weight were 2.87±0.27 MP/ind and 0.014±0.001 MP/g respectively. The length, weight, and condition factor of the fish did not correlate with MP abundance insert ignore into journalissuearticles values(Spearman’s correlation, p > 0.05);. Four different polymer types were determined in the digestive tract of the specimens. The composition of polymers consisted of 44.58% polyethylene terephthalate insert ignore into journalissuearticles values(PET);, 34.94% polypropylene insert ignore into journalissuearticles values(PP);, 10.84% polyethylene insert ignore into journalissuearticles values(PE);, and 9.64% polyamide insert ignore into journalissuearticles values(PA);. The determined shapes were fiber insert ignore into journalissuearticles values(67.47%);, fragment insert ignore into journalissuearticles values(20.48%);, and film insert ignore into journalissuearticles values(12.05%);. The size range of MP particles was ranged between 132 μm to 4850 μm, and the average was 1522.45±131.22 μm.
