“…2 and 3). Munuera et al (2021) found little effect of microplastics on Pb accumulation in the muscle of the crustacean Callinectes sapidus but a high effect in the hepatopancreas.

There has been little research on the pollution of drifted debris in terrestrial ecosystems in coastal areas compared to research focusing on aquatic environment and aquatic organisms. In this study, two species of terrestrial hermit crabs and three species of coastal plants were collected from a polluted site (Nita) and a control site (Furuzamami) in Zamami Island, Okinawa, and analysed to evaluate element contamination in order to evaluate the risk of drifted debris as a source of trace element pollution in terrestrial ecosystems. In both species of terrestrial hermit crabs, Cd was detected at significantly higher concentrations in both the muscle and hepatopancreas of individuals collected from the polluted site. In addition, Pb, often contained in polyvinyl chloride products along with Cd, had higher concentrations in the hepatopancreas of terrestrial hermit crabs in the contaminated site than in the control site. Among the three coastal plants, Pandanus tectorius was the most sensitive to trace element pollution via drifted debris. In general, plants tended to accumulate elements in accordance with their leachability from plastics. This result suggested that trace elements, leaching from drifted debris to soils, accumulated in the plants. These results indicate that leaching rates from drifted plastics have a greater effect on element accumulation in plants than in terrestrial hermit crabs. The degree of influence of the leaching rate of elements from drifting debris differed between the hermit crabs and plants. In addition, the accumulation of elements that were easily adsorbed by plastics was observed in each species. In the environment, drifted debris is potentially hazardous as a medium of contamination to organisms, as it adsorbs various elements during their transport in the ocean.

“…The species (fish), the concentrations of MPs and Cd, and how the metal was administrated could all have led to these differences. However, in a recent study, Munuera et al [25] found no differences in the accumulation of another trace toxic element (Pb) in blue crabs exposed to the same concentrations of MPs (25 µg L −1 ). Thus, differences in the responses to the MPs could be associated with the species.…”

The blue crab (Callinectes sapidus) is of great interest in toxicological research due to its characteristics, habits, and ease of handling, and has been used in several experimental studies [25][26][27].

Aquatic ecosystems are severely threatened by the presence of a multitude of pollutants. In seas and oceans, the amount of plastics continues to increase and there is great concern about toxic element accumulation. Specifically, cadmium (Cd), a toxic metal, is highly relevant to public health safety due to its ability to accumulate in the internal tissues of crustaceans; likewise, microplastics (MPs) are emerging as pollutants capable of causing alterations in marine organisms. The aim of this study was thus to evaluate the accumulation and distribution of Cd in the tissue of blue crabs (Callinectes sapidus) chronically exposed to MPs (25 μg L−1). In total, 24 crabs were exposed in water for 118 days to 2 types of MPs (virgin and oxidised). During the final 21 days of the experiment, the crabs were fed with tuna liver, a viscera in which Cd accumulates (mean of 7.262 µg g−1). The presence of MPs caused no changes in Cd concentrations in either the haemolymph or tissues (hepatopancreas, gills, and muscles) of the crabs, although for oxidised MPs, there was a positive correlation between Cd concentrations in the hepatopancreas and muscles, a relevant finding for food safety.

“…For example, research results showed that MPs, encapsulated within fecal pellets of the copepod Centropages typicus, could be transferred to copepod Calanus helgolandicus via coprophagy [42]. This could also increase their potential to enhance the transport of other pollutants absorbing on the MPs [37,45].…”

The presence of plastic cosmetic microbeads in the environment due to their extensive use in society and inevitable dispersal into wastewater is concerning. Therefore, it is vital to understand the processes of microplastic uptake and elimination by aquatic organisms, and to further assess their potential to cause harmful effects and wider impacts. We therefore investigated the short-term (48-h) and long-term (21-d) uptake, elimination, and effects of exposure to polyethylene microbeads (a mixture of fragments and spheres extracted from commercially available facial scrubs) on the freshwater snail, Biomphalaria glabrata. We found fast uptake in the short-term (75 μg/g/h) and the long-term (6.94 μg/g/h) in B. glabrata exposed to 800 particles/200-mL and 80 particles/200-mL, respectively. Irregular fragments were more easily ingested and egested compared to spheres (ANOVA, p < 0.05) in both 48-h and 21-d exposures. The mean size of the fragments in B. glabrata tissues (413 ± 16 μm) after 48-h exposure was significantly larger than that of the standard sample (369 ± 26 μm) (ANOVA, F3,20 = 3.339, p = 0.033), suggesting that aggregation in the gut may occur. Floating feces containing microbeads were observed in the long-term exposure, which could alter the fate, behavior, and bioavailability of egested microbeads. No significant effects on survival and growth were shown within 48-h or 21-d exposure periods. Thus, further studies on the specific features of microplastics (e.g., their shape and size) influencing uptake and elimination, as well as toxic molecular mechanisms, should be explored in future ecotoxicological studies.
