“…Similarly, larger individuals have a reduced dependence on annelids, increasing their consumption of 304 bivalves, echinoderms and vertebrate prey (Rijnsdorp and Vingerhoed, 2001). Polychaetes, such as Nereis 305 (Lourenço et al, 2017) and Arenicola (Van Cauwenberghe et al, 2015) have also been seen to take in plastics in the 306 wild, and may represent a further route of transfer to plaice; however, this could not be confirmed in the current 307 analysis due to the highly degraded state of soft bodied prey. 308…”

Microplastic pollution is apparent throughout the marine environment from deep ocean sediments to coastal habitats. Most of this is believed to originate on land, although marine activities, such as fishing and shipping, also contribute to the release and redistribution of microplastic. The relative importance of these maritime plastic sources, the manner by which they are distributed in the environment, and their effect on uptake by marine organisms are yet to be fully quantified. In this study, the relative impact of fishing activities on microplastic uptake by demersal fish and crustaceans was explored. Local fishing intensity, proximity to land and mean water velocity are compared to microplastic uptake in plaice, Pleuronectes platessa, and spider crab, Maja squinado, from the Celtic Sea. Observations were also made of microplastic contamination in ingested sand eels, Ammodytes tobianus, to establish a potential route of trophic transfer. This study is the first to identify microplastic contamination in spider crab and to document trophic transfer in the wild. Individuals were sampled from sites of varied fishing intensity in the Celtic Sea, and their stomach contents examined for the presence of microplastic. Contamination was observed in 50% of P. platessa, 42.4% of M. squinado, and 44.4% of A. tobianus. Locations of highest plastic abundance varied between P. platessa and M. squinado, indicating that different factors influence the uptake of microplastic in these two taxa. No significant link was observed between fishing effort and microplastic abundance; however, proximity to land was linked to increased abundance in M. squinado and Observations of whole prey demonstrate ongoing trophic transfer from A. tobianus to P. platessa. The lack of significant difference in microplastic abundance between predator and prey suggests that microplastic is not retained by P. platessa.

“…Higher concentrations of microplastics were found in a predatory shellfish from the Persian Gulf, which lead the authors to suggest trophic transfer of microplastics in the food web without quantification in the prey (Naji et al 2018). Seabird fecal pellets contained a similar composition of fibers to those which were identified in their macroinvertebrate prey which suggests that trophic transfer may be occurring (Lourenço et al 2017). All predatory marine organisms are susceptible to ingest microplastic through their prey.…”

“…Cole et al (2015) observed that microplastics encapsulated within the fecal pellets can be transferred between coprophagous copepod species. Furthermore, floating microplastics that wash onto the shore are available to invertebrates in the intertidal (Lourenço et al 2017). Unsurprisingly, microplastic is not only ingested by marine invertebrates.…”

Plastic has become indispensable for human life. When plastic debris is discarded into waterways, these items can interact with organisms. Of particular concern are microscopic plastic particles (microplastics) which are subject to ingestion by several taxa. This review summarizes the results of cutting-edge research about the interactions between a range of aquatic species and microplastics, including effects on biota physiology and secondary ingestion. Uptake pathways via digestive or ventilatory systems are discussed, including (1) the physical penetration of microplastic particles into cellular structures, (2) leaching of chemical additives or adsorbed persistent organic pollutants (POPs), and (3) consequences of bacterial or viral microbiota contamination associated with microplastic ingestion. Following uptake, a number of individual-level effects have been observed, including reduction of feeding activities, reduced growth and reproduction through cellular modifications, and oxidative stress. Microplastic-associated effects on marine biota have become increasingly investigated with growing concerns regarding human health through trophic transfer. We argue that research on the cellular interactions with microplastics provide an understanding of their impact to the organisms' fitness and, therefore, its ability to sustain their functional role in the ecosystem. The review summarizes information from 236 scientific publications. Of those, only 4.6% extrapolate their research of microplastic intake on individual species to the impact on ecosystem functioning. We emphasize the need for risk evaluation from organismal effects to an ecosystem level to effectively evaluate the effect of microplastic pollution on marine environments. Further studies are encouraged to investigate sublethal effects in the context of environmentally relevant microplastic pollution conditions.

“…This occurs as a process of physiological adaptation of mangroves where pneumatophores and buffer roots will function as effective filters by holding back the wave energy and turbulence produced by the sea (Horstman et al, 2014;Norris et al, 2017).Such a mechanism also allows mangroves to trap objects carried by currents entering the coastal area, for example, plastic litter. The role of pneumatophores mangrove as a plastic litter trap has a higher contribution in trapping waste (Barasarathi et al, 2011;Lima et al, 2014;Mohamed Nor and Obbard, 2014;Lourenço et al, 2017;Naji et al, 2017). Plastic litter caught in the mangrove ecosystem shows different retention depending on the hydrodynamics of the object.…”

HighlightThe issue of plastic litter and microplastics which is currently of special concern in global particularly IndonesiaThe review of size, colour and shape of microplastics that becomes part of the plastic litterThe observed review highlight of plastic litter and microplastics impact on environmental health particularly aquatic biotaAbstractThe negative impact that comes from plastic litter in the aquatic environment is a scourge for the entire world including Indonesia.Plastic litter has a huge influence on the most biota who lives in symbiosis with along the aquatic environment as it is able to sustainability. Moreover, there are other factors that cause the death of aquatic biota. Nowadays, the negative impact of plastic litter occurs on an ongoing basis through the food chain process which until now has not been well studied. Therefore, it is necessary to do further studies on the influence of the food chain as a vector of plastic litter distribution, particularly microplastic on aquatic biota from the first trophic level to high trophic levels.
