Summary: Organic ultraviolet filters (OUVFs) and nanoplastics (NPs) are two important new pollutants that widely coexist in freshwater and coastal habitats. This study comprehensively investigated the neurotoxicity and interaction neurotoxicity of typical OUVFs and NPs on zebrafish. The results showed that both OUVFs and NPs induced neurotoxic effects on zebrafish, with BM-DBM specifically interfering with neurotransmitter systems. Additionally, synergistic and antagonistic effects were observed between PS-NPs and BM-DBM in inducing apoptosis in neuronal cells and developmental neurotoxicity, respectively.

Summary: This study investigated the effects of co-exposure to arsenic (As) and polystyrene-nanoplastics (PSNPs) on liver toxicity and revealed the underlying toxicity mechanisms. The findings showed that co-exposure to As and PSNPs induced significant pathological changes in the liver and activated excessive autophagy, apoptosis, and pyroptosis. These findings provide a better understanding of the interactions between As and PSNPs exposure and the molecular mechanisms of hepatotoxicity.

Summary: The presence of antibiotics in source waters may affect the growth and formation of harmful algal blooms dominated by Microcystis aeruginosa. A study investigated the responses of this cyanobacterium to the antibiotic roxithromycin (ROX) at environmentally relevant concentrations. The results showed that ROX influenced the growth, microcystin production, and release of algal organic matters of M. aeruginosa, indicating potential effects on water quality and the formation of harmful algal blooms.

Summary: This study conducted a 35-day chronic toxicity experiment on mice to observe the effects of exposure to Cadmium (Cd) and polystyrene nanoplastics (PSNPs). The results showed that combined exposure to Cd and PSNPs increased the mice's growth toxicity and kidney damage. Moreover, it was found that Cd and PSNPs co-exposure led to oxidative stress, increased iron concentration, and induced ferroptosis and excessive mitophagy in the kidneys. This study provides new insights into the combined toxic effect of heavy metals and PSNPs on mammals.

Summary: The study found that at environmentally relevant concentrations, the tire wear particles (TWP) currently measured in the ocean environment are unlikely to pose a threat to common coastal copepods. However, when the TWP concentration exceeds MP concentrations in coastal waters by more than 100 times, the type, concentration, food concentration, and feeding mode of copepods interact to influence feeding and pellet production.

Summary: Most studies on microplastics have been conducted using pristine particles, neglecting the effects of weathering. Current weathering protocols are not sufficient for microplastics research. There is a need to use environmentally relevant microplastics and critically assess the appropriateness of weathering methods in future research efforts.

Summary: The lack of studies on the toxicity of microplastics (MP) at environmentally relevant concentrations and exposure times is concerning. In this study, the potential adverse effects of low density polyethylene (LDPE) microplastics on two species of competing amphipods were analyzed. The results showed that both amphipods effectively ingested and egested LDPE microplastics, and high concentrations of LDPE microplastics had negative impacts on mortality, swimming ability, and oxidative stress levels. G. lacustris was more sensitive to LDPE microplastics and may lose its competitiveness in MP polluted environments.

Summary: Microplastics have been found to be widely distributed in aquatic ecosystems and this study investigated their accumulation in the guts of zooplankton using aggregated-induced emission (AIE) technology. Both micro- and nano-sized plastic particles were readily ingested by Daphnia magna, with larger-sized and positively charged particles accumulating the most. The presence of algae inhibited the ingestion and depuration of microplastics. Furthermore, the accumulation of microplastics in D. magna led to acidification of gut pH, increased esterase activity, and induced gut inflammation.

Summary: This study assesses the impact of two types of dissolved organic matter (DOM) on the bioavailability of copper (Cu) to phytoplankton. Results show that at higher Cu concentrations (100 nM), DOM decreases Cu internalisation in phytoplankton, consistent with ASV measurements. However, at lower Cu concentrations (20 nM), organic complexes appear to be partially bioavailable, challenging the general applicability of the biotic ligand model (BLM).

Summary: The study revealed that different psychoactive compounds had varying effects on the aggressive behavior of chub, with citalopram and methamphetamine generally increasing aggression while tramadol and sertraline did not. Analysis of pollutant concentration in the brain showed a positive linear relationship between citalopram concentration and aggression, with no such effect seen for other compounds or their metabolites. Structural break analyses also identified concentration thresholds in brain tissue for citalopram and sertraline, from which a significant effect on behavior was observed.

Summary: This study investigated the potential developmental neurotoxicity and underlying mechanisms of DBDPE in zebrafish embryos. The results suggest that DBDPE may affect the locomotor regulatory network via different mechanisms at lower and higher concentrations, with disruption of the cholinergic system possibly playing a role at higher concentrations.

Summary: A better understanding of the interaction between nanoplastics and methanogenic archaea is crucial for assessing the ecological safety of nanoplastics. This study found that functionalized polystyrene nanoparticles can affect the DNA-mediated transposition and metabolic processes of Methanosarcina acetivorans C2A. The surface groups of the nanoparticles control their risk on the archaea and may affect global methane emissions.

Summary: The plastic concentration in terrestrial systems is much higher than that in marine ecosystems, leading to concerns about their impact on agricultural sustainability. Previous research on nanoplastic transport in soil relied on qualitative predictions, but lacked direct measurements of interfacial forces. This study conducted multiscale investigations and found that amino-modified nanoplastics were more mobile than carboxyl-modified nanoplastics. The transport of both types of nanoplastics was influenced by ionic strength and pH. Hydrophilicity/hydrophobicity-mediated interactions and particle heterogeneity interfered with interfacial forces, contradicting the qualitative predictions of existing theory. The combination of theory and atomic force microscopy can provide valuable insights into the fate of nanoparticles in soil.

Summary: Microplastics (MPs) in natural environments undergo complex aging processes, changing their interactions with coexisting antibiotics, and posing unpredictable ecological risks. This study used non-thermal plasma technology to simulate various radical oxidation and physical reactions, investigating the joint toxicity of aged MPs and antibiotics at the molecular level, and revealing the molecular responses of bacteria to the coexposure.

Summary: The inhibition of methane production in anaerobic digestion by long chain fatty acids (LCFA) is mainly caused by the limitation of VFAs conversion to methane. It was found that LCFA enhances the adhesion force between bubbles by increasing electrical double layer (EDL) repulsion and decreasing hydrophobic interactions, which leads to enhanced bubble separation from anaerobic granules and reduced bubble-bubble coalescence probability.
