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.

This study investigates microbial colonization of plastics in Caribbean coastal waters. We deployed five polymer types, on set with a mild UV-pretreatment and one without UV-pretreatment, for 4.5 months the water column sediment at two locations, analyzed epiplastic biofilms 16S rRNA gene sequencing. While significant influence location habitat was apparent, we could not detect notable effects related to type or community composition. Nevertheless, potential plastic hydrocarbon degraders constituted up 43 % sequences from biofilms, suggesting an affinity plastic. Indeed, utilizing 13C-labeled PE PP, determined incorporation plastic-derived carbon into biomass. measured isotopically labeled fatty acids incubations 13C both sediments, whether virgin pre-weathered UV light. The apparent biodegradation benthic habitats challenges perception marine sediments as final sink polyolefins.

Large quantities of plastic enter the oceans each year providing extensive attachment surfaces for marine microbes yet understanding their interactions and colonization debris remains limited. We investigated microbial various types (polyethylene, polystyrene, polyethylene-terephthalate, nylon) in ex-situ incubation experiments. Plastic films, both UV-pretreated untreated, were exposed to seawater from a coastal an offshore location North Sea. 16S rRNA amplicon sequencing was employed assess community structures after 5, 10, 30, 45 days incubation. Our findings show significant influence time, origin type on succession. also identified several genera associated with hydrocarbon or degradation potential as well selecting specific plastics such Ketobacter Microbacterium. results highlight role microorganisms biodegradation support idea that colonizers seemingly select distinct substrate types.
