Microplastics (MPs) have attracted global concern because of their harmful effects on marine biota; toxic properties can negatively impact aquatic ecosystems. Fish is an essential source protein for humans, playing a crucial role in daily food intake. Until recently, MPs were addressed primarily as environmental pollutants, but they are now increasingly recognized contaminants the supply. The present review has comprehended current knowledge MP contamination freshwater and fishes Asia, including 112 peer-reviewed sources from 2016 to 2023. recorded 422 Asian (345 77 freshwater) be contaminated with MPs. Clarias gariepinus Selaroides leptolepi shown maximum environments respectively. Omnivorous carnivorous exhibited higher susceptibility ingesting Benthopelagic, demersal, reef-associated habitats identified more prone accumulation.

Abstract Microplastics (MPs) pollution has wreaked havoc on biodiversity and food safety globally. The false ingestion of MPs causes harmful effects organisms, resulting in a decline biodiversity. present review comprehended the current knowledge MP contamination Crustacea Mollusca from 75 peer‐reviewed articles published Asia between 2015 2023. A total 79 species (27 52 Mollusca) have been recorded to be contaminated with MPs. Out 27 Crustacea, Metopograpsus quadridentatus (327.56 MPs/individual) Balanus albicostatus (0.42 showed highest lowest contamination, respectively. Mollusca, Dolabella auricularia (2325 Crassostrea gigas Mytilus edulis (0.2 In terms country‐wise China number both phylums among Asia. Findings indices revealed very high risk all countries.

Abstract The escalating issue of microplastic (MP) pollution poses a significant threat to the marine environment due increasing plastic production and improper waste management. current investigation was aimed at quantifying MP concentration on 25 beaches Maharashtra coast, India. Beach sediments (1 kg) were collected from each site, with five replicates evaluate extent MPs. samples homogenized, three 20 g replicas prepared for subsequent analysis. Later, sieved, MPs extracted using previously published protocols. abundance found as 1.56 ± 0.79 MPs/g, ranges 0.43 0.07 3 0.37 MPs/g. Fibers most abundant shape Size‐wise classification revealed dominance <1 mm 1–2 mm‐sized Blue‐ black‐colored recorded dominantly. Polymer identification polyurethane, polypropylene, polyvinyl chloride, acrylic or polymethyl methacrylate, rubber. findings that be higher highly impacted sites, followed by moderately sites low‐impacted possibly different degree anthropogenic pressure. study recommended urgent need effective policy prevent plastics accumulation in coastal State, Practitioner Points investigated distribution microplastics environment, specifically sediments. common type fibers, fragments films.

Abstract Plastic pollution poses a pervasive threat to ecosystems worldwide, jeopardizing marine life, contaminating water sources, and perpetuating global environmental crisis. Spatial temporal distribution of beach debris was quantitatively assessed on three recreational beaches in Gujarat State, India. A total six categories were recorded with mean 0.9 items/m 2 number 3.62 g/m weight. Mean concentrations weight per item did not vary significantly between study sites. Highest observed October 2021 at all Around 90% macro-debris (2.5–100 cm), white transparent colours most frequently encountered. Based Clean Coast Index findings, sites categorized as " dirty ". Abundance revealed that had very high abundance plastics compared other debris. Recreational activities beaches, tourism, extensive fishing can be the possible source State.

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.
