“…Possibly, translucent fibers result from colored fibers owing to exposure to acids during the acid treatment process ( Devriese et al, 2015 ). Similar to our findings, the presence of MPs of various colors in various pelagic and demersal fishes has also been confirmed ( Boerger et al, 2010 ; Lusher, McHugh & Thompson, 2013 ; Bellas et al., 2016 ; Ory et al, 2017 ; Gurjar et al, 2021 ).…”

“…Given that MPs are the same size as sediments and planktonic prey items for lower trophic organisms, the possibility of their ingestion by benthic and pelagic biota, with diverse feeding behaviors, increases as the density of MPs in water increases ( Wright, Thompson & Galloway, 2013 ). Further, the presence of MPs in shrimps in various geographical regions of the world has been previously reported in several studies ( Devriese et al, 2015 ; Abbasi et al, 2018 ; Carreras-Colom et al, 2018 ; Akhbarizadeh, Moore & Keshavarzi, 2019 ; Cau et al, 2019 ; Curren et al, 2020 ; Daniel, Ashraf & Thomas, 2020 ; Hossain et al, 2020 ; Nan et al, 2020 ; Gurjar et al, 2021 ). In this study, shrimps were chosen because they play an important role in the food chain and provide food for a variety of animals, ranging from fish to humans.…”

“…This observation can be attributed to the fact that L. vannamei has a smaller mouth aperture than M. rosenbergii . Thus, its GT was predominated by smaller MPs ( Gurjar et al, 2021 ). Hossain et al (2020) found that 70% of the MPs in the GT of tiger shrimps are larger-size fractions (1–5 mm) compared with those in the GT of brown shrimps, in whose GT, smaller MPs (<1000 µm) are predominant (83%).…”

Background The presence of plastic particles in freshwater species is becoming a global concern owing to the potential impact on food security and human health. In this study, we investigated the presence microplastics (MPs) in two economically important freshwater species: the giant freshwater prawn (Macrobrachium rosenbergii) and the white leg shrimp (Litopenaeus vannamei) cultured in a polyculture pond in the central part of Thailand. Methods The gastrointestinal tract (GT) of 300 giant freshwater prawn (160 female and 140 male) and 150 white leg shrimp specimens were investigated for the presence of MPs. Results From the pooled samples, a total of 1,166 MP items were identified. Specifically, the GTs of female and male freshwater prawns and white leg shrimps contained an average of 33.31 ± 19.42, 33.43 ± 19.07, and 11.00 ± 4.60 MP items per individual, respectively. Further, their mean MP contents per g of gut material were 32.66 ± 5.10, 32.14 ± 4.85, and 10.28 ± 1.19 MP items, respectively. In the GT of these species, MPs with sizes in the range 500–1000 µm, were predominant, and white/transparent MPs were most prevalent (63.67%). Furthermore, regarding the morphotypes of the MPs, fibers, fragments, films, and spheres were frequently observed, with fibers shows predominance. Specifically, the proportions of fibers in the GTs of female Macrobrachium rosenbergii, male Macrobrachium rosenbergii, and Litopenaeus vannamei were 83.3, 79.91, and 46.06%, respectively. Four MP polymer types, polyethylene, polycaprolactone, polyvinyl alcohol, and acrylonitrile butadiene styrene, were also identified via FTIR spectroscopy, which further confirmed the presence of MPs in the GT of the freshwater-cultured species. Discussion Our findings indicated that consuming shrimps and prawns without first removing the MPs from their GTs is one of the mean by which humans get exposed to MPs. Thus, MPs in freshwater species can be passed down the food chain to humans.

“…Despite these reasons, the chemicals that have been used to provide bright colours to the polymeric substances are found to pose secondary toxic effects in aquatic systems. Gurjar et al 2021 while studying the presence of microplastics in shrimps of Arabian Sea, reported that dark coloured microplastics especially black were present for about 30.16%, followed by red within the shrimp body, and it may be because of their visual similarity to that of their prey (Gurjar et al 2021). Other than physical properties, the surface properties of microplastics when coated with industrial chemicals, make them act as carriers for transporting toxic metals, such as rare earth metals and other pathogenic organisms to enter food chain through adsorption-diffusion mechanisms (Lee et al 2021).…”

Microplastics in mangroves and coral reef ecosystems: a review

Microplastic pollution has recently been identified as a major issue for the health of ecosystems. Microplastics have typically sizes of less than 5 mm and occur in various forms, such as pellets, fibres, fragments, films, and granules. Mangroves and coral reefs are sensitive and restricted ecosystems that provide free ecological services such as coastal protection, maintaining natural cycles, hotspots of biodiversity and economically valuable goods. However, urbanization and industrial activities have started contaminating even these preserved ecosystems. Here we review sources, occurrence, and toxicity of microplastics in the trophic levels of mangrove and coral reef ecosystems. We present detection methods, such as microscopic identification and spectroscopy. We discuss mitigating measures that prevent the entry of microplastics into the marine environment.

“…Trophic transfer, bioaccumulation and biomagnification of microplastic in seafood create a real way for intake of MRs by humans. Plastic debris has been found in fishes, shellfish, mussels and cockles designated for human consumption [144][145][146][147][148].…”

Major water-polluting microplastics (for example, polyethylene, polypropylene and others) have lower density than water. Therefore, they are concentrated in the neustonic layer near the water-air interface altogether with dissolved or colloidal natural organic matter, hydrophobic cells and spores of bacteria. This can cause environmental and public health problems because the floating micro- and nanoparticles of plastics could be coated with biofilm of hydrophobic and often putative pathogenic bacteria. Biofilm-coated microplastics are more attractive for consumption by aquatic animals than pure microplastics, and that increases the negative impacts of microplastics. So, impacts of even small quantities of microplastics in aquatic environments must be accounted for considering their accumulation in the micro-layer of water-air interphase and its interaction with bacterioneuston. Microorganisms attached to the surface of microplastic particles could interact with them, use them as substrates for growth, to change properties and biodegrade. The study of microbial life on the surface of microplastic particles is one of the key topics to understanding their role in the environment.
