“…The estuary in Goa showed 3950 ± 930 MP/kg sediment at a depth of 2 -3 m. Here, however, the samples were taken in the estuary at a location before the river meets the sea [152]. The Kayamkulam estuary near Kollam, Kerala, shows much less MP contamination at 433 M/kg sediment [153]. Dominant polymers were found to be polyester, followed by PE and PP.…”

Microplastic has been found in all major waterbodies in the world. Many examples of ingestion of microplastic by marine organisms have been reported. This presence of microplastic in marine organisms gives it the possibility to penetrate the human food chain by increasing the chance of microplastic in seafood targeted for human consumption. Although it is known that parts of the Indian Ocean suffer from significant plastic pollution, much of the systematic research on the microplastic abundance in different regions of the Indian Ocean stems only from the last five years. This manuscript reviews the available literature of 2015-2022 on the presence of microplastics in commercially important fish species in the Indian Ocean. The literature data on microplastic content on beaches, in subtidal sediment, in the sediment from the ocean floor, and in surface water of different regions of the Indian Ocean is reviewed, also.

“…The shallow sediment contained more microfibers, and the rate of microfiber deposition in the sediment was strongly related to the expected change in production in the study area based on annual plastic production [76]. Furthermore, seawater inundation in the estuary and the distance of sampling points from the coast had a significant influence on the distribution of fibres and films in estuary sediments [77]. The most common polymer types found there were PE, PP, PVC, PA, PAM, and PES [96][97][98].…”

The estuarine ecosystem is under threat due to the addition of different anthropogenic pollutants. Among the various pollutants, microplastics(MPs), and antibiotics play a significant role in affecting estuarine organisms and human health by transport through the food chain. In the estuaries, microorganisms, including pathogens, colonise microplastics by the development of biofilms. Estuaries have long been home to MPs, served as novel hubs for the transmission of Antibiotic Resistance Genes (ARGs). As a result of their continual interactions with a variety of aquatic creatures, MP-associated bacterial communities will eventually present a transfer opportunity to organisms that consume MPs. To comprehend the presence of microplastics and ARGs in the estuaries, a thorough review is necessary. This review discusses the various sources of MPs and antibiotic pollution, as well as the transport of ARGs via biofilm formed on MPs. Furthermore, the factors affecting biofilm formation in estuaries are reviewed. In addition, the transport of ARGs by microbial populations within biofilm is discussed. The ARGs are transported into the food chain, which will be a threat to human health. Hence, the occurrence of antibiotic-resistant genes in fish is discussed.

“…Estuarine regions, acting as vital interfaces between rivers and oceans, inevitably serve as convergence and deposition points for microplastics. 6 Particularly, locations such as the Kayamkulam Estuary (southwest coast of India), 7 the Solent Estuarine System (UK), 8 Tampa Bay (USA) 3 and Setiu Wetlands (Malaysia) 9 have reported substantial quantities of microplastic particles. The pronounced accumulation potential of plastics, particularly microplastics, within estuaries poses significant threats to both biodiversity and human food security.…”
