Summary: Asian clams (Corbicula fluminea) have been widely used in biomonitoring and environmental applications due to their high enrichment capacity and rapid response to pollutants. This review summarizes the accumulation process of metals and organic pollutants by C. fluminea, and discusses their environmental behavior and applications. The accumulation ability of Cu, Zn, and Mn is significantly higher than other metals, attributed to their high uptake rate constant and low elimination rate constant. However, knowledge gaps exist regarding the accumulation of organic pollutants and nanoparticles, and the physiological mechanisms underlying the accumulation of environmental pollutants by C. fluminea. The review also highlights the potential applications of C. fluminea in wastewater treatment, pest management, and blocking invasive bivalve spread.

Summary: Freshwater cyanobacteria produce highly toxic secondary metabolites, which can be transported downstream by rivers and waterways into the sea. Estuarine and coastal aquaculture sites exposed to toxic cyanobacteria raise concerns that shellfish may accumulate and transfer cyanotoxins in the food web. This study aims to describe the competitive pattern of uptake and depuration of a wide range of microcystins (MC-LR, MC-LF, MC-LW, MC-LY, [Asp3]-MC-LR/[Dha7]-MC-LR, MC-HiIR) and nodularins (NOD cyclic and linear) within the common blue mussel Mytilus edulis exposed to a combined culture of Microcystis aeruginosa and Nodularia spumigena into the coastal environment. Different distribution profiles of MCs/NODs in the experimental system were observed. The majority of MCs/NODs were present intracellularly which is representative of healthy cyanobacterial cultures, with MC-LR and NOD the most abundant analogues. Higher removal rate was observed for NOD ( approximate to 96%) compared to MCs ( approximate to 50%) from the water phase. Accumulation of toxins in M. edulis was fast, reaching up to 3.4 mu g/g shellfish tissue four days after the end of the 3-days exposure period, with NOD (1.72 mu g/g) and MC-LR (0.74 mu g/g) as the dominant toxins, followed by MC-LF (0.35 mu g/g) and MC-LW (0.31 mu g/g). Following the end of the exposure period depuration was incomplete after 27 days (0.49 mu g/g of MCs/NODs). MCs/NODs were also present in faecal material and extrapallial fluid after 24 h of exposure with MCs the main contributors to the total cyanotoxin load in faecal material and NOD in the extrapallial fluid. Maximum concentration of MCs/NODs accumulated in a typical portion of mussels (20 mussels, approximate to 4 g each) was beyond greater the acute, seasonal and lifetime tolerable daily intake. Even after 27 days of depuration, consuming mussels harvested during even short term harmful algae blooms in close proximity to shellfish beds might carry a high health risk, highlighting the need for testing.

Summary: The quality of lake wetlands has decreased due to elevated concentrations of certain trace elements. Consuming crayfish from these trace element concentrated lake wetlands can be hazardous for waterbirds and human health. This study quantified the bioaccumulation of Cd, Ni, Pb, and Zn in sediments and abdominal muscles of Procambarus clarkii in Caohai lake wetland, China. The results showed significantly elevated levels of Cd, Ni, Pb, and Zn in sediment, and some samples of crayfish had Cd, Pb, and Zn levels exceeding the maximum permissible limits. These findings suggest that lake sediment could be an important source of feed for P. clarkii and that normal consumption of crayfish posed low to no health risk for waterbirds and local inhabitants.

Summary: Chemical contaminant concentrations in wild organisms are used to assess environmental status, but they are challenged by intra- and inter-species variability and regional differences. This study monitored concentrations of trace elements and organic pollutants in 8 fish species from three French regions, aiming to identify contaminated species or regions and determine how to account for variability in environmental assessment. The results showed higher concentrations in benthic and demersal piscivores, while lipid-normalized concentrations were similar in most teleost species. Regional differences were observed, with higher concentrations in the Eastern English Channel and Gulf of Lions compared to the Bay of Biscay. Taxa-specific thresholds might be a more practical approach for environmental assessment than normalizing to trophic levels.

Summary: Stable isotopes are a valuable tool for studying diet and migration in squid, which are important in marine food webs. The Patagonian long-finned squid fishery in Falkland Islands waters is managed separately for different fishing seasons and sub-areas, but the factors causing differences in recruitment timing and squid size between sub-areas have not been resolved. In this study, stable isotopes were used to reconstruct a chronological record of habitat and feeding variations, and the results indicate that spatial differences in life history parameters are not due to dietary variation. The data obtained from this study can be used for future research on the role of squid in the Patagonian Shelf marine ecosystem, as well as for studying other loliginid squid species.

Summary: Climate change is transforming bioenergetic landscapes and challenging animals' coping mechanisms. In the Arctic, warming temperatures are affecting the energy expenditure of Arctic seabirds, but plasticity in daily energy expenditure (DEE) currently buffers fitness against climate change. However, modeling suggests that continued warming may lead to unsustainable increases in DEE.

Summary: This study demonstrates that increased pCO2 (partial pressure of carbon dioxide) has no impact on the accumulation efficiency of mercury (both organo-mercury and inorganic mercury) in cuttlefish, as well as the organotropism. Furthermore, the study reveals that the digestive gland is a key organ for in vivo demethylation of organo-mercury. Consequently, cuttlefish exposed to environmental levels of organo-mercury may undergo in vivo demethylation.

Summary: This study compared the stable isotope signatures of muscle and gladius tissues of the autumn and spring spawning cohorts and different sizes of the Patagonian longfin squid. The results showed that the autumn spawning cohort had higher delta C-13 values and delta N-15 values increased with increasing size. Muscle tissue was enriched in N-15 but slightly depleted in C-13 compared to gladius tissue. The estimated trophic level of adult squid was 3.2, with no significant differences between spawning cohorts.

Summary: Behavioral ecotoxicology has grown due to standardized analyses, but it mainly focuses on a few model species, limiting extrapolation and prediction of toxicological effects. To overcome this, assessing critical species-specific behavioral responses is recommended, such as cephalopods. We discuss the relevance of cephalopods as a toxicological model based on research on environmental stressors and the challenge of quantifying color change.
