Summary: Mesocosms have emerged as a useful tool for studying the environmental impacts of engineered nanomaterials over the past decade. Study results show that mesocosm size, experiment duration, and indoor/outdoor location play major roles in defining the distribution of ENMs/metals. While benthic communities may face higher exposure levels, planktonic organisms are generally exposed to lower concentrations of potentially more reactive and toxic ENM species.

Summary: Analytical limitations have hindered the determination of nanopollution characteristics from nano-enabled products (NEPs), which are actual sources of nanopollution. This study examined the properties of engineered nanomaterials (ENMs) in 18 commercial products, revealing their diverse morphologies and negative charges. Despite identifying key ENM characteristics for environmental risk assessment, challenges persist in accurately determining concentrations in NEPs.

Summary: This study found that nanoparticles can affect the functionality and genome of chloroplasts and mitochondria in A. thaliana, and different nanoparticles have different effects, which are related to the toxicity and dissolution rate of the metal salts. These findings suggest that changes in stoichiometry are an adaptive response to nanoparticle exposure.

Summary: The application of pristine nanomaterials (PNMs) for environment remediation still faces challenges due to aggregation, low stability, sub-optimum efficiency, and non-uniformity. On the other hand, modified nanomaterials (MNMs) have shown significant potential in enhancing remediation strategies by decreasing aggregation and increasing metal bioavailability. However, there is a lack of comprehensive review evaluating the efficacy and environmental impact of MNMs against PNMs. This critical review identifies barriers and discusses strategies to increase stability and activity of nanomaterials at reaction sites, highlighting the potential of MNMs in remediation.

Summary: This study used Life Cycle Assessment (LCA) to measure the impact of concrete production and found that two methods of Life Cycle Impact Assessment (LCIA) were quite close in most impact categories. The results suggest that both methods are appropriate for LCA studies in Brazil. Additionally, supplier choice can become a strategy to reduce impacts on ozone depletion and global warming categories.

Summary: The study investigated the toxicity effects of 'form specific' engineered nanomaterials (ENMs) and ions released from nano-enabled products (NEPs) on various organisms, finding that both ENMs and ions contributed to the effects to varying extents. Daphnia magna and Spirodela polyrhiza were the most and least sensitive test organisms, respectively. The most toxic effects were from ENMs and ions released from sanitisers and sunscreens.

Summary: An external oxidant-free system was developed to generate reactive oxygen species (ROS) for the decontamination of antibiotics in natural water systems. Cobalt-doped Fe3S4 nanoflowers were designed and synthesized, which showed superior ability to adsorb and activate oxygen molecules. The use of these nanoflowers resulted in a significant improvement in the degradation rate of sulfamethoxazole and boosted the degradation efficiency of antibiotics. This study provides a new strategy for the control of emerging organics in water systems and sheds light on the mechanisms of in-situ ROS generation.

Summary: Environmental conditions in aquatic ecosystems play a significant role in transforming toxic chemicals, such as copper nanoparticles, and influencing their bioavailability and toxicity. This study investigated the accumulation and toxicity of aged nano-Cu in marine phytoplankton, and found that the dissolution rate of nano-Cu decreased during the first 4 weeks before increasing rapidly after 15 weeks. The toxicity of nano-Cu to phytoplankton decreased with particle aging from 0 to 4 weeks, but increased significantly after 15 weeks due to elevated Cu dissolution.

Summary: The coexistence of pharmaceuticals and heavy metals poses a serious threat to aquatic environments. Adsorbents have been widely used for the simultaneous removal of pharmaceuticals and metals from water. The effectiveness of the adsorption process depends on various factors such as the characteristics of the adsorbents and contaminants, temperature, pH, inorganic ions, and natural organic matter. Bridging and competition effects play significant roles in promoting or inhibiting the adsorption process. This review provides valuable insights into the theoretical knowledge in this field and may contribute to the prevention and control of the coexistence of pharmaceuticals and heavy metals in wastewater.

Summary: This study optimized a targeted plant proteomics approach by developing and optimizing signature peptide selection, liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis method, and sample preparation method. Different protein extraction and precipitation methods, as well as digestion methods, were evaluated. The results showed that the phenol extraction method using fresh plant tissue, coupled with trypsin digestion, was the best sample preparation method for targeted proteomics studies. The optimized approach yielded higher peptide concentrations and detected additional signature peptides. This study provides a workflow for optimizing targeted proteomics studies.

Summary: Inorganic nanomaterials such as TiO2 and ZnO provide effective UV protection, but concerns about their potential health and ecological implications have arisen. However, most studies suggest that the risks associated with these materials are minimal and their impact on human and environmental health is limited. Further research is needed to assess if sensitive habitats are at an elevated risk.

Summary: Modeling and field sampling are important for assessing PFAS sources and risks. Legacy and newer PFAS were detected in wastewater treatment plant samples. Predictive models were used to estimate PFAS loads and population size and urban land use were found to be predictors of PFAS loads. The study demonstrates the practicality of using predictive models and field sampling for assessing PFAS risks.

Summary: This study investigates the metabolic perturbations in green alga C. reinhardtii exposed to different sizes and concentrations of nTiO(2). The results show that nTiO(2) exposure induces perturbations in amino acid, nucleotide, fatty acid metabolism, among others, but does not affect photosynthesis. The perturbations are size and concentration-dependent and also impact the overall nutrition of the microalgal cell.
