“…Similar to these studies, approximately, 5.25 trillion particles weighing 268940 tons float in the world's oceans surface [47]. MPs have been reported along various beaches as well as Yellow sea, China [48]; Nallathanni Island, Gulf of Mannar, India [49]; Aveiro beach of Portugal [50]; France [51] and Turkey [52]. These beaches were mostly characterized by touristic zones, which obviously attract MPs pollution.…”

Microplastics (MPs) with particles lower than 5mm in size, are crucial pollution of increasing ecotoxicological concern in the environments. Lately, studies on MPs have been documented globally due to increasing awareness of the potential risks for human health and for the environment. However due to limitations of different analytical methods and environmental assessment risk, MPs distribution and biological effects are still database topics. To clarify this gap, this study brings out a wide range of scientific literature related to MPs studies in different environmental compartments as well as sediments, oceans, coastlines, uptake and the health effect. The environmental and health risk related to microplastic contamination is still unclear.

“…These regions being a major fishery zone often forms the prime location for fish landing and other fishing related activities. Furthermore, beaches being a major zone of coastal tourism and pilgrimage activities get heavily impacted by pollution related to human interventions (Krishnakumar et al, 2018). The present study was conducted in GoM and PB, two major coastal water bodies in the northern Indian Ocean threatened by the impacts associated with fishing and tourism-related activities.…”

“…These coastal regions characterized by diverse habitats such as coral reef, sea grass meadows and mangrove forests, forms rich feeding and breeding grounds for a wide variety of aquatic organisms, especially many economically important fish species. Hence these regions are more explored for its fisheries and tourism values which subsequently forms the root cause of microplastic contamination (Krishnakumar et al, 2018). Taking into consideration the susceptibility of these sensitive coastal ecosystems to anthropogenic interferences, the state government has launched a ''Green Rameswaram'' project at Rameswaram Island from 2014 intending to create a clean, environment friendly and green Rameswaram island, aimed at preserving its ecology and marine biodiversity (Vasudeo et al, 2018).…”

Impact of microplastic pollution on the marine environment and its biota is a major concern globally. Gulf of Mannar (GoM) and Palk Bay (PB) are two important biodiversity hotspots along the south-east coast of India. However, in the recent years the intense tourism and fishery activities have made the ecosystem and biota of these two ecologically significant coastal zones vulnerable to microplastic contamination. Hence, a comparative study on the seasonal distribution of microplastics in the surface waters, sediments, and in commercially important fishes were conducted to evaluate the threats imposed by microplastics on the environment and biota of both these coastal ecosystems. Microplastic distribution in the surface waters and sediments of GoM and PB exhibited conspicuous seasonal variation and showed positive correlation with the seasonal current patterns. In the surface waters of GoM, microplastics were abundant during the South West Monsoon whereas in PB it was high during the Early Winter Monsoon period. In the sediments of PB, microplastics was more during Spring Inter-monsoon and South West Monsoon whereas in GoM it was high during Late Winter Monsoon. Fragments, of size 1 to 5 mm formed the abundant microplastic type in the surface waters whereas in the sediments, fragments of size < 1 mm dominated. Of the gut content of the 613 fishes belonging to 12 families examined, microplastics were more in pelagic than demersal fishes with higher incidences in the family Clupeidae (42%). Among the fishes studied, microplastic ingestion was more in Selaroides leptolepis (27.77%), Sphyraena sp. (14.28%), Pelates quadrilineatus (12%), Caranx sp. (10.34%), and Sphyraena barracuda (10%).

“…The study concludes that the white coloured micro plastics could be because of the plastic bottles which get washed away or are carried by winds to the water. S.KrishnaKumar et al, [21], conducted a study on the Nallathanni Island in India. Samples collected from different sites showed the presence of microplastics, fibers and household plastic waste including cosmetic scrubbers, insect repellents, resin pellets and sunscreens.…”

Microplastic pollution is a new emerging problem to our generation, with lack of proper disposal and tones of production. Every year tones of plastic is disposed in the water bodies and which gets weathered and results in the production of microplastics, which when ingested by aquatic organisms leads to their mortality and many serious issues. The microplastics are good adsorbents and absorb all the chemical and metals in the water causing mortality in fishes. They also act as pathogen carriers and lead to the water born diseases. Our review study finds that there is a need to evaluate the effects on the fresh water organisms as the literature on fresh water is scarce.
