Both NPs and PCBs are emerging contaminants widely distributed in the environment, it is worth exploring whether combination of two causes serious pollution harm. Therefore, we studied effects PS-NPs PCB-44 alone together after 96 h 21 d exposure to C. pyrenoidosa. The results showed that affected cell cycle pyrenoidosa inhibited its normal growth. Physiologically, increased relative conductivity algal solution, decreased surface hydrophobicity cells, reduced synthesis chlorophyll a b. Biochemically, induced oxidative stress with significant changes enzymatic activities SOD CAT MDA content. Moreover, expression photosynthesis-related genes (psbA, rbcL, rbcS) all responded, negatively affecting photosynthesis. In particular, toxic were observed single co-exposure PCB-44, similar trends acute chronic experiments. Taken together, caused negative on growth physiological biochemistry These provide scientific information further explore aquatic organisms ecosystems.

Mussels are highly efficient filter feeders, playing a crucial role in managing eutrophication and assessing pollution. Although research on nanoplastic (NP) toxicity marine organisms is expanding, studies freshwater species remain limited despite ecosystems being disproportionately biodiverse vulnerable to pollutants. Here, we quantified the effects of polystyrene nanoplastics (PS-NPs, 50 nm) at concentrations 0, 2, 20, 200 μg/L different growth stages mussel Cristaria plicata. After 45-day exposure, PS-NPs ≥ 20 damaged intestinal epithelial cilia both age groups. Exposure significantly increased malondialdehyde levels decreased superoxide dismutase activity groups, with adults showing significant rise total protein content juveniles exhibiting marked increases respiratory ammonia excretion rates. Additionally, PS-NP exposure altered relative abundance gut microbial phyla, including Proteobacteria, Firmicutes, Verrucomicrobiota, Bacteroidota, Fusobacteriota also affected adults. Juveniles were more sensitive physiological changes, whereas exhibited greater microbiota shifts response exposure. Therefore, this study provides new insights into stage-specific integrity biochemical health mussels, underscoring need for targeted management strategies protect ecosystems.
