“…In controlled laboratory experiments, ingestion of microplastics and related chemicals in fish has caused liver stress, endocrine disruption and behavioural changes [110], but several studies have found no effects through exposure to microplastics [111][112][113]. The effects of ingestion in wildlife or humans are currently unknown [110], but there is a potential health risk [114]. In a study by Barbosa and colleagues [115], the intake of microplastics was investigated in three commercially important fish species (n = 150) from the northeast Atlantic Ocean.…”

Health and sustainability problems have become a central theme in dialogue in both the scientific community and the public. Our individual choices have a profound, advantageous or disadvantageous impact on our health; the same can be said about our environmental footprint. In this area, we can also make decisions that affect the physical environment positively or negatively. Our narrative review aims to demonstrate that healthy plant-based choices in our diet are linked to choices beneficial for our environment and that these two seemingly distant aspects converge in the context of plant-based diets. We have collected, compared and discussed the results of life cycle analysis (LCA) articles on the current state of the effect of food choice on our environment. Furthermore, we would like to show the opportunities and constraints of implementing plant-based diets.

“…MPs (51%) isolated from the viscera, gills, and eviscerated flesh of dried fishes, such as greenback mullet ( Chelon subviridis ), Belanger’s croaker ( Johnius belangerii ), Indian mackerel ( Rastrelliger kanagurta ), and spotty-face anchovy ( Stolephorus waitei ). Furthermore, the presence of MPs in 14 marine dried-fish products from seven Asian countries had been assessed by Piyawardhana et al [ 68 ], and most the dried fishes were detected to contain MPs that had a fibrous structure (~80%) and PE, PET, PS, PVC, or PP as their polymer component. In addition to that, MPs in anchovy products bought from the local fishing markets in the western Gulf of Thailand contained 0.47–3.18 fibrous MPs/gram of dried fish [ 69 ].…”

While plastics are already notorious for their accumulation in the environment, which poses environmental challenges, invisible microplastics (MPS) are an even greater challenge. This review focuses on consolidating the reports available on MP accumulation in edible marine and freshwater fishes, shrimps, and crabs. The reality as to whether MPs in these edible aquatic organisms are really a cause of high concern is questioned and discussed. While the entrails of aquatic organisms are reported to contain high levels of MPs, because these products are consumed after the removal of the entrails and gut area in the majority of cases, the MP threat is questionable. The existence of MPs in these aquatic sources is validated but their potency in harming humans, aquatic organisms, and other interlinked species is unassessed. To overcome the difficulty in tracing the movement of MPs in a bigger ecosystem, this review proposes laboratory-based pilot studies mimicking real-world conditions, which will help us to understand the kinetics of MPs in the food chain. The effects of MPs on human welfare and health are yet to be assessed, and this is another gap that needs attention.

“…Microplastic occurrence in the aquatic fauna has been studied in water systems of North America (Hurt et al 2020;Peters and Bratton 2016), Europe (Bellas et al 2016;McGoran et al 2017), Asia (Zhang et al 2020;Phuong et al 2022;Piyawardhana et al 2022), Australia (Cannon et al 2016;Su et al 2019), Africa (Biginagwa et al 2016;Naidoo et al 2016) and South America (Silva-Cavalcanti et al 2017;Ribeiro-Brasil et al 2020). In the Brazilian Amazon region, microplastics were reported from the stomach of fishes in Amapá state (Pegado Souza et al 2018), the stomachs of piranha and pacu fishes from the Xingu River, and the gills and stomsch of stream fish in Pará state (Andrade et al 2019;Ribeiro-Brasil et al 2020).…”

Microplastic occurrence in fish species from the Iquitos region in Peru, western Amazonia

The contamination of aquatic environments by microplastic has become a major threat to biodiversity. The presence of microplastic is documented in the aquatic fauna of the oceans, but, in the Amazon basin, reports on microplastic occurrence are few. The present study surveyed microplastic occurrence in fishes in an area of the Peruvian Amazon. We sampled 61 specimens of 15 commercial species from local markets in the city of Iquitos, Loreto Department. We detected a total of 2337 microplastic particles, 1096 in the gills and 1241 in the internal organs (esophagus, stomach, intestine, liver, gonads, pancreas, swim bladder and heart). The prevalence of microplastic particles was 100% and the overall average abundance was of 38.3 particles per individual (17.9 particles per individual in gills and 20.3 particles per individual in internal organs). Most particles were found in carnivorous fish. There was no correlation of particle abundance with fish standard length and weight. These results provided evidence of the degree of microplastic contamination of the fish fauna in the region of Iquitos.
