“…Pearl spot being an endemic species in brackish water of the region and an important part of the local cuisine are a matter of concern with the high abundance of MP in its body. MP abundance (34 ± 12.66 par/ individual) in E. suratensisis comparable to studies on the same species from Vembanad with 13 ± 5 number /individual(Nikki et al 2021). Toxicological study conducted on E. suratensis using PVC (Polyvinyl chloride) microplastics recorded signi cant changes in growth, behavioral and enzymatic activities (Vijayaraghavan et al 2022).…”

Microplastics (MPs) are gaining global attention in recent years due to its widespread distribution and potential health impacts. The present study focuses on the distribution and characterization of microplastics in the sediments and bottom dwelling organisms of Kavvayi and Kumbla backwaters of Northern Malabar region, Kerala, India. MP isolation procedure including density separation, organic matter digestion and membrane ltration followed by visual and spectral analysis using optical microscope and confocal Raman spectroscopy have been utilised for the microplastic evaluation. Microplastics of size range up to 500 nanometres were analysed and presence of MPs were detected in all samples with an average abundance of 99.5 ± 69.43 particles/ kg and 96.57 ± 29.96 particles/ kg in Kavvayi and Kumbla backwaters respectively. Raman spectral analysis con rmed about 50% of MPs to be synthetic elastomers with the remaining half encompassed by PA, PE, PEST, PU and PP. Higher abundance of MPs in the edible aquatic organisms like clams, prawns and shes con rmed the transfer of MP from the environment into living organisms envisages the need of further investigation on toxicological impacts and management strategies.

“…41,42 MPs can enter freshwater environments through various pathways, including agricultural runoff, industrial effluents, fishing activities, tourism, atmospheric fallout, plastic waste dumping, stormwater discharge, road runoff, flooding events, wastewater treatment plant effluents, and domestic sewage. 43,53 In India, MPs research work is mostly focused on coastal environments, coastal sediments, 46,47 seawater, 48 biota, 49 sea salt, 50 lakes, 30,33,51 and fish. 49 To the best of our knowledge, only a few studies of MPs in India's freshwater systems have been conducted to date.…”

Microplastics in Freshwater Ecosystems of India: Current Trends and Future Perspectives

Microplastics (MPs)�i.e., plastic particles less than 5 mm in length�are becoming a growing environmental concern due to their potential ecotoxicological impacts on aquatic ecosystems. In India, MPs contamination is a significantly growing problem due to increased plastic production as well as its low rate of recycling. As a result, MPs research work in India has gained considerable attention in the last two decades. The objective of this study is to conduct a comprehensive review of the existing scientific literature on MPs in freshwater ecosystems (e.g., lakes and rivers) of India. A bibliographical search was used to conduct the literature review across a number of databases including ScienceDirect, Google Scholar, and ResearchGate. We found that in comparison to the marine ecosystem the source, transport, and fate of MPs in freshwater ecosystems of India are still underexplored, and we found only 18 relevant papers. This review work reveals that there is no standard procedure for separating MPs from water and sediment samples, and as a result, comparing the results was a challenging task. The larger MPs (>500 μm) in water and sediments were identified most commonly using the attenuated total reflection (ATR) Fourier Transform Infrared (FTIR) spectroscopy technique (ATR-FTIR), whereas smaller-sized MPs (<500 μm) were identified using FTIR fitted with a confocal microscope, also known as μ-FTIR imaging or chemical imaging. We found that white-colored fibers and fragments of polypropylene (PP), polyethylene terephthalate (PET), and polyethylene (PE) were the most common polymer types in the freshwater ecosystems of India. Although research on MPs in freshwater ecosystems of India has gained momentum over the past decade, the literature review reveals a limited understanding of the impact of MPs' weathering patterns, the role of biofouling, and the role of water hyacinths on freshwater ecosystem services in India. Furthermore, the fluxes of MPs to the Indian oceans are not constrained, and atmospheric transport in high-altitude mountains, which have already been made fragile by climate change, has not been fully investigated. This study, therefore, calls for additional assessments of MPs in freshwater ecosystems�particularly in the central parts of India.

Microplastics are considered as an emerging global issue due to its detrimental effects on natural ecosystem. These microplastics have ill-effects on aquatic biota and possible hazards to human health. Contamination of fish by microplastics is a major hazard that requires special focus. We examined the presence of Microplastics in edible and inedible tissues of Mugil cephalus (Mullet) from Ashtamudi Lake, a RAMSAR site. 53.33% of the sampled 60 fishes had ingested plastic particles. The average abundance of microplastics was 0.08 ± 0.009 and 0.31 ± 0.016 items/fish respectively in the edible and inedible tissues. The most commonly found MPs were fibre (70.83%). Red and black coloured microplastics were the most commonly ingested particle. Fourier Transform Infra-Red spectroscopy characterisations of the debris revealed, polyethylene as the most abundant polymer type in both edible and inedible tissue. The results point to the possibility of small-scale human ingestion of microplastics through the consumption of filter feeders from this lake.
