Unveiling the Microplastics Menace in Freshwater Fishes: Evidence from the Panjnad Barrage, South Punjab, Pakistan

Fishes, Journal Year: 2025, Volume and Issue: 10(5), P. 198 - 198

This study explored the prevalence and types of microplastic (MP) pollution in three fish species—Labeo rohita, Wallago attu, Cirrhinus mrigala—collected from Panjnad Barrage South Punjab, Pakistan. MPs were analyzed gastrointestinal tracts (GITs), gills, muscles 90 samples. Advanced analytical techniques, including Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy/Energy-Dispersive X-Ray (SEM/EDX), Gas Chromatography/Mass Spectrometry (GC/MS), deployed, confirming polymeric composition presence various additives. Quantitative qualitative analyses revealed significant variations MP accumulation across tissues, with GIT consistently showing highest count, gills having concentration per gram, exhibiting lowest amount accumulation. attu was found to have accumulated microparticles among all species due its feeding habits habitat. Fibers fragments predominant MPs, yellow red being most frequent colors. Polypropylene (PP) polyethylene (PE) primary polymers identified, alongside other like terephthalate (PET) polyvinyl chloride (PVC). The size distribution indicated that mid-sized particles (150–50 µm) abundant while smaller (<50 muscles, suggesting different levels bioavailability tissue penetration. Overall, results suggest agricultural activities are a major contributor plastic Barrage. These findings highlight ecological health impacts contamination, stressing importance targeted mitigation strategies eliminate waste aquatic environments.
