Summary: The study found that exposure to FC60 led to increased oxidative stress in clams, significant changes in antioxidant enzyme activities in gills, and damage to lipids and proteins in digestive glands. FC60 accumulation was higher in digestive glands compared to gills, and haemolymph parameters were slightly affected by FC60 exposure. Overall, clam gills were identified as the target tissue for FC60 toxicity, with potential long-term consequences for the organism due to damage to lipids and proteins.

Summary: Studies have shown the presence of nanoparticles, particularly carbon nanotubes, in aquatic ecosystems, raising concerns about their toxicity when combined with other pollutants. This study evaluated the effects of carboxylated multi-walled carbon nanotubes and chromium on the metabolic capacity, oxidative status, and neurologic status of two filter feeder organisms: Ruditapes decussatus and R. philippinarum. Results revealed species-specific accumulation of chromium, with higher values in R. decussatus. Only R. philippinarum showed inhibition of antioxidant defenses and neurotoxic effects. The interaction between contaminants did not affect antioxidant enzyme activities and neuro status. However, the combined exposure to both contaminants altered the metabolic capacity of R. decussatus. Both clams were tolerant to the contaminants but showed a significant accumulation capacity, posing a potential transfer of contaminants to humans.

Summary: This study investigated the combined impacts of polyethylene microplastics (PE MPs) and an organic pollutant (BaA) on Manila clam. The results showed that high concentration of PE MPs had a greater effect on the biological parameters of the clams, and the role of PE MPs in transporting BaA into clam tissues was negligible.

Summary: This study investigated the bioaccumulation, detoxification, and biomacromolecular damage mechanisms of benzo[a]pyrene (B[a]P) at the subcellular level in the scallop Chlamys farreri. The results showed that B[a]P accumulation exhibited a time-dose effect, and the intracellular migration order of B[a]P was speculated. The activities of B[a]P metabolizing enzymes were significantly affected by B[a]P exposure, and biomacromolecules in specific subcellular fractions were more vulnerable to damage.

Summary: The study found that melanin synthesis increased by 503.2% in animals exposed to BaP, while the synthesis decreased by 25.6% with the BaP + aNF interaction, resulting in high toxicity and cell degeneration. Phagocytic activity reduced to 37.6% in animals exposed to BaP, but the BaP + aNF interaction led to restoration of phagocytosis, reaching 419.23%. In conclusion, BaP and aNF are toxic to P. cuvieri, posing risks to herpetofauna.

Summary: This study systematically investigated the lipid metabolism disturbance in scallop digestive glands exposed to Benzo[a]pyrene (B[a]P) through lipidomics, transcriptomics, molecular, and biochemical analysis. Results showed that lipid content increased and membrane structures were disrupted in digestive glands of scallops exposed to 10 μg/L B[a]P. It was speculated that B[a]P induced lipid accumulation by up-regulating lipid synthesis-related gene expression, down-regulating lipolysis-related gene expression, and interfering with lipid transport. This study provides important insights into the mechanisms of lipid metabolism disturbance and bioaccumulation of B[a]P in aquatic organisms.

Summary: This study investigated the effects of Benzo[a]pyrene (B[a]P) on the immune function of Chlamys farreri hemocytes and found that B[a]P caused changes in both detoxification metabolism and immune signal transduction. Additionally, the metabolite of B[a]P, BPDE, mediated signal transduction through the protein tyrosine kinase pathway in bivalves. The study also demonstrated the significant role of the complement and lectin systems in regulating immune response.

Summary: This study analyzed fifteen nutritional quality evaluation indicators of Ruditapes philippinarum over 7 months and determined the most important indicators using various chemometric methods. Significant differences in nutritional quality were observed across the 7 months, with the coefficient of variation values ranging from 1.67% to 43.47%. Principal component analysis and system cluster analysis were used to extract essential quality indicators for efficient quality control in aquaculture.

Summary: A monthly survey was conducted to investigate the feeding selectivity of Ruditapes philippinarum using high-throughput sequencing identification and visual grading technology. The study found that the dominant species in the shellfish culture area and the stomachs of R. philippinarum was Karlodinium veneficum. The selectivity index indicated a preference for consuming Dinophyta and Chlorophyta, while avoiding Bacillariophyta, Chrysophyta and Cryptophyta. The study also found that chemical oxygen demand, organic phosphorus, pH, and inorganic nitrogen to phosphorus ratio had significant effects on the preferred phytoplankton communities.

Summary: Macrobenthic bioturbation affects the environment and variations in habitat, which also impacts the macrobenthic community. There is a mutually causal relationship between macrobenthos and habitat factors. The dominant role of Manila clam in the interaction with the habitat suggests that the invasion of other macrobenthos into the bottom-sowing culture zones may be accidental or inevitable.
