“…However, this was not evaluated in our study. Decreased filtration rates and acetylcholinesterase activity were found in clams exposed to 80 nm NPs, 6 µm MPs, and ciprofloxacin [32] . Ciprofloxacin, an antibiotic found in municipal wastewater, was shown to worsen the inhibition potential of NPs when co-administered to clams.…”

The ubiquity of plastics in environments worldwide is raising concerns about their toxicity to organisms. The purpose of this study was to investigate simple means to determine the exposure and effects of nanoplastics (NPs) in the freshwater mussels Elliptio complanata (E. complanata ). NP tissue levels were determined using a plasmonic nanogold sensor probe and effects were determined using the refractive index (RI) and thiol-reaction rates (TRR) in protein-dense tissue extracts. This method was adapted to quantitatively measure the concentration of NPs in tissues using a salting-out extraction in the presence of acetonitrile (ACN). Concentrated solutions of albumin were first spiked with NPs to evaluate changes in RI and TRR to determine crowding effects. The data revealed that NPs readily decreased the RI and TRR in albumin in vitro . These three simple assays were then applied on freshwater mussels caged for 3 months at various sites in a largely populated area. Mussels downstream of the city center and found at the street runoff discharge sites were highly contaminated by NPs and the RI and TRR were also reduced. In conclusion, simple and readily accessible assays to assess the NP contamination based on a visual nanogold sensor technology, and the effects of plastics are proposed for freshwater mussels.

“…Fluorescence intensity measurements were obtained each time the exposure solution was prepared and replaced to ensure the accurate concentration of the exposure solution throughout the study. A period of 168 h (exposure to 7 days) is generally acknowledged as PS-NPs significantly. , Every exposure solution was prepared 24 h beforehand, and the cultivation conditions maintained during the exposure phase were identical to those during the acclimation period, with no feeding involved. Half of the exposure solution in each aquarium was substituted on a daily basis.…”

Nanoplastics (NPs) are emerging contaminants having persistent nature, diverse ecological impacts, and potential food safety risks. Here, we examined the ecotoxicity of 80 nm polystyrene nanoplastics (PS-NPs) at environmentally relevant concentrations (ERCs, 10 and 100 μg/L), and sublethal concentrations (SLCs, 500 and 2500 μg/L) in Magallana hongkongensis. Results showed that SLCs significantly (p < 0.05) increased superoxide dismutase (SOD), catalase (CAT), and alkaline phosphatase (AKP) activities and altered tnfα, cat, gst, sod, and se-gpx genetic expressions. Further, PS-NP exposure at both levels reduced beneficial bacteria and increased potentially pathogenic bacteria in the gut. In transcriptomic analysis, 5118 and 4180 differentially expressed genes (DEGs) were identified at ERCs, while 5665 and 4817 DEGs were found at SLCs, respectively. Upregulated DEGs enriched lysosomes, ABC transporters, and apoptosis pathways, while downregulated DEGs enriched ribosomal pathways. Overall, ERCs significantly altered gut microbiota and transcriptomic responses, while SLCs, in addition, also impacted the antioxidant and immune systems.
