Tracking synthetic microdebris contamination in a highly urbanized estuary through crabs as sentinel species: An ecological trait-based approach

Indirect Effects on Tourism and Water Quality along the Argentinian Atlantic Coast during COVID-19 Pandemic Scenarios

“…Recent studies found that these face masks quickly shed microplastics (fibers) in these environments due to mechanical and chemical actions (wind, ultraviolet radiation, waves, etc .) ( e.g ., Chen et al ., 2021; Forero López et al ., 2022; Shen et al ., 2021) and then can be carriers of metals that bioaccumulate in organisms (Truchet et al ., 2022). Thus, during warm seasons like spring/summer, an increase of these plastics will undoubtedly occur in Argentinian coasts, as currently detected.…”

Macroecotoxicology: Challenges and opportunities to study broad-scale biodiversity patterns under the effect of microplastics contamination

“…Species traits related to MPs accumulation or physiological and biochemical effects can reveal the species' characteristics that would make them vulnerable to this contaminant [43]. Our review indicates that, in the case of crustaceans, smaller species, burrowers, swimmers, and omnivores tend to accumulate more MPs [18,22,44]. For benthic invertebrates, omnivores and deposit feeders were the most affected species [24], and their performance traits (e.g., mortality and reproduction) were as affected as the functional traits (e.g., feeding and behavior) [5].…”

Prevalence of microplastics in Peruvian mangrove sediments and edible mangrove species

“…In contrast, N. granulata, C. sapidus and M. mercenaria presented lower values than U. occidentalis (Villagran et al, 2020;Capparelli et al, 2022) (Table 2). Although, there was no correlation between the number of microplastics in the mangrove crab and the sediment (Pearson: R = -0.02; p-value >0.05), there's a possibility that U. occidentalis interact with the presence of microplastics in the upper intertidal sediment from the Coastal Upper Zone, Channel Upper Zone, and Tourist Central Zone (Díaz-Jaramillo et al, 2021;Truchet et al, 2022) (S1 and S2A -C).…”

“…Among the commercial mangrove and estuary crabs, the omnivorous Metopograpsus quadridentatus has been reported with the highest microplastic abundance (33 items/g -327.56 items/ind) (Mufti et al, 2020), while the herbivorous crab Chiromantes dehaani consumed the least amount of microplastic (0.74-4.96 items/ind) (Zhang et al, 2021). In Latin America, U. occidentalis has less items of microplastics in the gills and stomachs than C. angulatus and L. uruguayensis (Truchet et al, 2022). In contrast, N. granulata, C. sapidus and M. mercenaria presented lower values than U. occidentalis (Villagran et al, 2020;Capparelli et al, 2022) (Table 2).…”
