Different pollutants often coexist in natural environments, making it crucial to monitor and study the ecotoxicological effects of composite aquatic environments. Nanoplastics heavy metals are emerging environmental that can affect health organisms threaten human via food chain. In this study, zebrafish was employed as a model organism explore short-term exposure polystyrene nanoplastics (PS-NPs) metal copper ions (Cu2+) either individually or combination on fish behavior. First, single combined toxicity Cu2+ PS-NPs adult investigated obtain LC50 values two at 24, 48, 72, 96 h. Then, sub-lethal concentrations (0.06, 0.15, 0.3 mg/L), (5, 10, 15 mg/L) binary mixtures containing (0.06 mg/L + 10 mg/L, 0.15 swim speed individual distance within 4 h were studied. The results show value for decreased with increase time, while showed no significant acute when concentration less than 20 time resulted 3.1–32.2% reduction different points compared alone. behavioral both induced hyperactivity aggregation phenomena levels; duration these correlated pollutants. exacerbated changes alone, reducing their average by 30.7–41.0%, 13.6–15.4%, 28.3–28.8%, respectively. Therefore, indicates exacerbate pollutants, also proves feasibility early warning NPs pollution based indicators.

Microplastics occurrence in commercial crab Scylla serrata from Kaveri River of Tamil Nadu: An emerging concern for community health

Water Environment Research, Journal Year: 2025, Volume and Issue: 97(2)

Abstract Microplastic (MPs) pollution has engulfed global aquatic systems, and the concerns about MPs translocation bioaccumulation in fish, crabs, other marine organisms are now an unpleasant truth. In past few years, freshwater particularly rivers, subsequently organisms, especially caught attention of researchers. Rivers provide livelihood to approximately 40% population through food potable water. Hence, assessment emerging contaminants like waterways associated fauna is crucial. This study assessed crab S. serrata across largest riverine system south India, Kaveri River. The were characterized by optical microscopy, field emission scanning electron microscopy‐energy dispersive X‐ray (FESEM–EDX) analysis for their number, shape, size, color. Polymer composition was analyzed using attenuated total reflectance Fourier‐transform infrared spectroscopy (ATR‐FTIR) Raman spectroscopy. Polypropylene (PP), polystyrene (PS), polyamide (PA), polyvinyl chloride (PVC) dominant plastic polymers intestine. Additionally, FE‐SEM revealed that have differential surface morphology with rough surfaces, porous structures, fissures, severe damage. Most comprised Na, Si, Mg, Cl, K, Ca, according EDX analyses. findings might insight into status at Kavery river could help formulating regulations reduction contamination rivers eventually protect environment human health. Practitioner Points first on identity properties crabs from River Mettur Dam. A simple cost‐effective approach extracting microplastics samples Dam, River, Salem District, Tamil Nadu, India. Microplastics detected ATR‐FTIR, FE‐SEM.
