Microplastic contamination in commercially important bivalves from the southwest coast of India

Oysters and mussels as equivalent sentinels of microplastics and natural particles in coastal environments

“…However, in the present study oysters and mussels demonstrated high equivalence considering levels and qualitative aspects of particles accumulated. Similar outcomes were observed in the Netherlands (Leslie et al, 2017), Iran (Jahromi et al, 2021), India (Joshy et al, 2022;Saha et al, 2021), France (Phuong et al, 2018) and South Korean (Cho et al, 2021;Jang et al, 2020), where oysters and mussels were also able to reflect characteristic of MPs present in surrounding environments.…”

Occurrence of microplastics in wild oysters (Crassostrea tulipa) from the Gulf of Guinea and their potential human exposure

“…Due to their abundant presence in waterbodies, they are more likely to be ingested by invertebrates such as oysters, mussels, shrimps and echinoderms ( Baechler et al., 2020 ; Hermabessiere et al., 2019 ; Mohsen et al., 2019 ; Patterson et al., 2019 ; Li et al., 2015 ; Vandermeersch et al., 2015 ) which could impair their feeding behaviour and disrupt their energy budget ( Lusher et al., 2013 ). The sources of these fibers in aquatic environments have been linked to the growing textile manufacturing and hospitality industries along major rivers and lakes that discharge directly into them ( Joshy et al., 2022 ; Browne et al., 2013 ). However, it is important to note that all the sampled locations in this study are active fishing sites where the loss of synthetic fishing gears (i.e., nets, ropes, and lines) could contribute to fibrous pollution.…”

“…These fibers may have been accessible to the organisms either because of wear and tear while the fishing gear was being used or possibly as a result of the dangers posed by abandoned, lost or discarded fishing gear, which does not appear to attract the attention of waste managers. Aside its use in the fishing industries, polyethylene and polypropylene are principal components of food packaging, plastic containers and the production of textiles ( Joshy et al., 2022 ; Gedik and Eryaşar, 2020 ).…”

A Systematic Review on Microplastic Contamination in Fishes of Asia: Polymeric Risk Assessment and Future Prospectives

“…Presently, more than 660 marine species are documented to be contaminated by plastics (Carbery et al, 2018; Claessens et al, 2013). Owing to their minute dimensions, MPs are prevalent across various trophic levels, including plankton, bivalves, and fish (Joshy et al, 2022; Lindeque et al, 2020; Sfriso et al, 2020; Teng et al, 2019). Microplastics can be taken up by fish via various pathways, such as false or accidental ingestion (active) and trophic transfer by the food chain (passive; Bhatt & Chauhan, 2022).…”
