“…However, in our study, clear, black, and blue microplastics were the most common with sizes below 0.25 mm (Figures 3 and 4). Other studies also reported that the clear or white color is the most predominant (Daniel et al, 2021;McGoran et al, 2020;Zhang et al, 2020a), as shown in Table 3. Organisms will eat microplastics colors that resemble their natural food (Ory et al, 2018), especially light colors (clear, white, and grey) and some black colors (Engler, 2012).…”

In northern Peru, the mangrove crab Ucides occidentalis is of great importance due to its ecological, economic, and social role. In this study, we reported for the first time the presence of microplastics in the gills and digestive tract of the mangrove crab U. occidentalis derived from local markets in Tumbes. Microplastics were identified in 100% of the crabs analyzed with a total of 921 items, 475 items (52.57%) found in the gills, and 446 (48.43%) found in the digestive tract. The size range was established in 2 to 250 µm, 250 to 500 µm, 500 to 1 mm, and 1 to 5 mm, microplastics with sizes between 2 and 250 µm were the most common with 53.79% in the digestive tract and 90% in the gills. A total of six different types of microplastic were recorded; The highest percentages for each tissue were fibers (59.64%–61.05%) and films (19.28%−36.63%), with clear fibers being the most prevalent microplastic type in both tissues. Microplastics with less than 250 µm size were found 90% in the gills and 53.79% in the crab digestive tract. Although the present study is a baseline for rapid identification of microplastics in mangrove crab, we suggested that these findings provided more information on the state of contamination as well as food security alert for local markets.

“…O caranguejo as preda devido a facilidade obtida, já que são indivíduos oportunistas quando se trata da alimentação (Farrell & Nelson, 2013). O microplástico pode ser transportado pelos caranguejos para outros níveis da cadeia alimentar, afetando outras espécies aquáticas, até mesmo a população humana que consome esses animais (Rainieri, & Barranco, 2019;McGoran et al, 2020). Os microplásticos são partículas que derivam de materiais particulados maiores e seu tamanho é variado.…”

Entre macrófitas e microplásticos: dieta de Crustacea Decapoda Dilocarcinus pagei (Stimpson, 1861) e Trichodactylus petropolitanus (Göldi, 1886) na região do Pantanal de Cáceres – MT

Caranguejos são abundantes no Pantanal e apresentam papel fundamental na cadeia trófica, pois fazem parte da dieta de mamíferos, aves, répteis e anfíbios dos ecossistemas pantaneiros. São encontrados, aproximadamente, 0.63 indivíduos/m² desses organismos no Pantanal, distribuídos em 6 espécies, entre elas, Dilocarcinus pagei (Stimpson, 1861) e Trichodactylus petropolitanus (Göldi, 1886). Esta pesquisa investigou a riqueza, abundância, morfologia e hábitos alimentares de caranguejos no Pantanal de Cáceres, sob influência urbana e área remota. As amostragens foram realizadas na Estação Ecológica de Taiamã (168 km de Cáceres) e no Rio Paraguai incorporado à paisagem da cidade de Cáceres - MT. As coletas foram feitas em bancos de macrófitas aquáticas usando tela de nylon de 2 m de comprimento x 1 m de largura. Ao todo, foram coletados 256 caranguejos sendo 226 pertencentes a espécie D. pagei e 20 da espécie T. petropolitanus. As duas espécies foram encontradas associadas às macrófitas Eichhornia crassipes e Eichhornia azurea, que formam bancos densos de plantas funcionando como locais de refúgio para os caranguejos em termos de abrigo, alimento e segurança contra predadores. Os organismos amostrados tiveram preferência, em sua base alimentar, por matéria orgânica, talo e raiz de macrófita. Adicionalmente, microplásticos e outros materiais particulados não identificados foram constatados no conteúdo alimentar, indicando prejuízo na dieta e na morfofisiologia dos caranguejos. Os nossos achados contribuem para elucidar a dieta de caranguejos no Pantanal e projetar os efeitos de poluentes, como os microplásticos, sobre esses organismos e na cadeia trófica aquática, podendo atingir a saúde humana.

“…Arenicola marina , an annelid species, has been reported to have MPs embedded in its gastrointestinal tracts (Besseling et al 2013 ). Some crustaceans like Carcinus maenas have also been reported with the presence of MPs in the digestive and respiratory tracts (McGoran et al 2020 ). These plastic particles are mistaken for food, leading to the blockade of essential body tracts which results in the generation of incorrect signals (Smith et al 2018 ; Ugwu et al 2021 ).…”

Microplastics (MPs) are ubiquitous pollutants persisting almost everywhere in the environment. With the increase in anthropogenic activities, MP accumulation is increasing enormously in aquatic, marine, and terrestrial ecosystems. Owing to the slow degradation of plastics, MPs show an increased biomagnification probability of persistent, bioaccumulative, and toxic substances thereby creating a threat to environmental biota. Thus, remediation of MP-pollutants requires efficient strategies to circumvent the mobilization of contaminants leaching into the water, soil, and ultimately to human beings. Over the years, several microorganisms have been characterized by the potential to degrade different plastic polymers through enzymatic actions. Metagenomics (MGs) is an effective way to discover novel microbial communities and access their functional genetics for the exploration and characterization of plastic-degrading microbial consortia and enzymes. MGs in combination with metatranscriptomics and metabolomics approaches are a powerful tool to identify and select remediation-efficient microbes in situ. Advancement in bioinformatics and sequencing tools allows rapid screening, mining, and prediction of genes that are capable of polymer degradation. This review comprehensively summarizes the growing threat of microplastics around the world and highlights the role of MGs and computational biology in building effective response strategies for MP remediation.
