Summary: The applications of CuO nanoparticles in industrial and agriculture have led to their increased concentrations in wastewater and accumulation in waste activated sludge, raising concerns about their impact on the production of medium-chain carboxylates (MCCs) from anaerobic fermentation of sludge. Our study showed that CuO NPs at 10-50 mg/g-TS significantly inhibit MCCs production, with reactive oxygen species generation being the key factor. However, at lower CuO NPs concentrations (0.5-2.5 mg/g-TS), MCCs production was enhanced. Molecular approaches and metaproteomic analysis revealed the impact of CuO NPs on microbial processes and protein expression levels related to MCCs production.

Summary: Environmental carbon nanomaterials, such as multi-walled carbon nanotubes and graphene oxides, interact with aromatic hydrocarbon pollutants, resulting in adverse effects on ecosystems and human health. The combined toxicity of carbon nanomaterials and benzo[a]pyrene is still unknown. Among the investigated carbon nanomaterials, MWCNTs-NH2, p-GO, and GO-COOH showed some alleviation of the cytotoxicity induced by benzo[a]pyrene, with GO-COOH exhibiting the strongest inhibitory effect. Mechanistically, GO-COOH reduced benzo[a]pyrene-induced cell apoptosis and cytotoxicity by regulating apoptotic proteins and maintaining mitochondrial membrane potential. These findings highlight the importance of the physicochemical properties of carbon nanomaterials in modulating the cytotoxicity of benzo[a]pyrene.

Summary: The probability of occupational exposure to carbon nanotubes (CNTs) is increasing due to their growing production and biomedical applications. As a result, the risk of co-exposure of nanomaterials with environmental pollutants is also increasing. This study investigated the toxicity of pristine single-walled CNTs (p-SWCNTs) and oxidized single-walled CNTs (SWCNT-COOHs) on cell responses to metal ions (Pb2+, Cu2+, and Cr(VI)). The findings suggest that understanding the effects of the exposure sequence of engineered nanomaterials and environmental pollutants on their toxicity is crucial for evaluating combined toxicity.

Summary: A comprehensive online database on the toxicity of ionic liquids (ILs) has been developed to aid in the design of environmentally friendly ILs using machine learning. The ILTox database contains manually curated data, including 1183 ILs and over 6700 pieces of toxicity data across different organisms. Machine learning models have been constructed using this database to analyze the relationship between IL structures and toxicities. The database has been used for virtual screening of desired IL properties from a large pool of ILs and has proven to be a valuable resource in understanding IL toxicity.

Summary: Bond length is an important structural parameter that can affect the activity of catalysts. In core-shell gold-palladium (Au@Pd) nanocatalysts, elongated Pd-Pd bonds resulting from lattice mismatches between Au and Pd are found to exhibit distinct catalytic activity. Surface-enhanced Raman scattering (SERS) spectra of chemisorbed 2,6-dimethylphenyl isocyanide (2,6-DMPI) were used to investigate the elongated Pd-Pd bonds on Au@Pd. The study revealed that strained sites with elongated Pd bonds are more than 100 times more active in a catalyzed Suzuki-Miyaura coupling reaction.

Summary: This study investigated the impact of nanoplastics (NPs) on the spread of antibiotic resistance genes (ARGs) and found that negatively charged polystyrene (PS) and PS-COOH enhanced ARG transfer at low concentrations, while transfer declined at higher concentrations. Conversely, PS-NH2 increased ARG transfer at all tested concentrations, with the highest promotion effect at 500 mg L-1. The effects on ARG transfer were a combination of ROS production-induced promotion and NP agglomeration-caused inhibition at high concentrations.

Summary: Nanoplastics can transport heavy metal ions and pose health risks when ingested through the food chain. This study investigated the induction of inflammatory responses in human cells by ion-adsorbed polystyrene NPs and found that intracellular ions played a role in the inflammation caused by these NPs. Machine learning models identified Cd2+ and Pb2+ as crucial for the increased expression of pro-inflammatory cytokines in different cell types. The activation of NF-kappa B and ERK1/2 pathways were associated with the high expression of pro-inflammatory cytokines in the respective cell types.

Summary: In this study, palladium (Pd) nanocrystals with different crystalline forms were synthesized, and the underlying mechanisms of ROS-mediated cytotoxicity were revealed. Nanocubes and nanooctahedrons/nanotetrahedrons triggered cytotoxicity by generating singlet oxygen (O-1(2)) and hydroxyl radicals (OH), respectively. Nanoconcave-tetrahedrons induced ROS-mediated cytotoxicity via activating the superoxide (O-2(-)) pathway. The alkalization of pH resulting from intracellular ROS conversion was identified as a new biomarker for analyzing cytotoxicity.
