Summary: Continuous release of nanoparticles (NPs) into marine coastal environments increases the risk of exposure to complex NP mixtures for marine organisms. This study aimed to investigate the independent and combined effects of exposure to nZnO, nTiO(2), and FC60 fullerene on the Manila clam Ruditapes philippinarum. The results showed increased bioaccumulation of NPs, oxidative stress, and damage to proteins, lipids, and DNA in all analyzed tissues. Proteomics analysis revealed protein modulation related to cytoskeleton and energetic metabolism. The digestive gland was the most affected tissue. The mixture of NPs caused greater detrimental effects compared to single exposures.

Summary: The study investigated the in vivo toxic effect of a mixture of TiO(2)NPs and ZnO NPs, revealing that the mixture induced a higher systemic toxicity than when TiO(2)NPs or ZnO NPs were used individually. Comprehensive risk assessments should be carried out on NP mixtures before their utilization in consumer products.

Summary: The study examined the application of ENMs in cosmetics and their associated risks to humans and the environment. A new methodology based on two-dimensional X-ray absorption imaging was introduced to address the dispersion state of ENMs in products. 2D-XRA proved effective in analyzing UV filter dispersion and product homogeneity, while Cryo-STEM allowed for more precise observation of ENM primary particles and phase distinctions.

Summary: In this study, TiO2 and ZnO nanoparticles of different sizes and crystallographic configuration were used to protect wood surfaces from UV radiation. The size and photoactivity of the nanoparticles were measured, and the effects on wood surfaces were evaluated after UV irradiation. The results showed that nanoparticles with lower photoactivity were more effective in reducing the impact of UV radiation on wood surfaces, and smaller nanoparticles were more effective in reducing photochemical reactions.

Summary: The study established the influence of the crystalline phase and agglomeration degree of TiO2 nanoparticles on photocatalytic hydroxyl radical formation and bacterial inactivation in TiO2/SiO2 composite coatings. A relationship between hydroxyl radicals' formation and charge carrier transfer mechanism between defect levels in SiO2 and TiO2 embedded nanoparticles was established through a simple spectroscopic method. This correlation complements the lack of mechanisms behind the photocatalytic activity in TiO2/SiO2 composites.

Summary: TiO2-Ag doped nanoparticulate (TiO2-Ag-NP) adhesive photocatalytic films were used to assess the ability to reduce indoor microbial particles. The films were applied in various living spaces and showed a reduction of microbial pollution by more than 70%. The correlation between the reduction of relative light unit (RLU) and colony forming units per cubic meter (CFU/m(3)) confirmed the efficacy of the TiO2-Ag-NP adhesive film in reducing microbial pollution.

Summary: This study demonstrates the significant antibacterial effect of a polymer-based composite layer containing titanium dioxide and zinc oxide against animal-origin Escherichia coli. The efficacy of the coating was not affected by different light intensities and distances. However, the presence of organic contaminants reduced the antibacterial potential of the coating.

Summary: In this study, the combined effects of tetracycline (TC) and titanium dioxide nanoparticles (TiO2 NPs) on the neurodevelopment of zebrafish larvae were investigated. The co-exposure of TC and TiO2 NPs resulted in increased embryonic malformation rates, abnormal nervous system development, and altered locomotor behavior in zebrafish embryos. Pathway enrichment analyses revealed significant effects on lipid metabolism and PPAR signaling pathway. Furthermore, the gene expression related to neural development was altered and the expression levels of neurotransmitters like 5-hydroxytryptamine, dopamine, acetylcholinesterase, and γ-aminobutyric acid were up-regulated. These findings demonstrated the potential neurotoxicity of TC and TiO2 NPs in zebrafish embryos.

Summary: The study evaluates the distributions of total PM2.5 of different sizes in New Delhi, India over 12 months and finds that ultrafine particles significantly contribute to total PM2.5 and are most cytotoxic to human lung epithelial cells. In March, higher amounts of reactive oxygen species are generated per unit mass for all sizes of PM, without correlation to metal content values.
