Summary: The rapid development of nanotechnology has led to the release of various products without fully understanding their potential impact on the environment. This study focuses on the effects of zinc oxide nanoparticles (ZnO-NPs) on non-target organisms, aiming to ensure human health and environmental safety. A systematic review of available data on the toxicity of ZnO-NPs to freshwater and marine/estuarine aquatic organisms was conducted. The findings suggest that freshwater invertebrates are the most commonly used organisms in ecotoxicological tests. The primary mechanisms of ZnO-NPs toxicity involve the release of Zn2+ ions and the generation of reactive oxygen species (ROS).

Summary: Understanding the uptake and elimination kinetics of engineered nanomaterials (ENMs) in aquatic organisms is crucial for assessing their environmental risks. This study compares different biokinetic models for non-dissolvable ENMs in freshwater organisms. The results show that no single model can accurately predict all experimental data, but first-order one-compartment models with storage fraction appear to be more flexible in describing various bioaccumulation patterns. It is recommended to use appropriate lengths for exposure and elimination periods in future experiments and report more information on particle characterization in the exposure medium.

Summary: The unsustainable manufacturing, utilization and inadequate handling of plastics have caused a significant increase in global plastic pollution. There is growing concern about the potential hazards associated with exposure to micro/nanoplastics (M/NPs). Understanding the environmental behavior of M/NPs, particularly in aquatic systems, where they are likely to accumulate, is crucial. The formation of a biocorona (BC) through interaction with biomolecules within aquatic organisms modifies the physicochemical attributes of M/NPs, such as size, stability, and surface charge. This review discusses the concept of BC formation, analytical techniques for characterizing it, and its implications on the toxicity, fate, and transport of M/NPs in the environment.

Summary: Microplastics are prevalent pollutants that can be found in aquatic ecosystems globally. They can be ingested by aquatic species and transferred through higher trophic level food webs. However, most studies on microplastic aquatic toxicity have been conducted in laboratory settings, and the impact of microplastics on aquatic species and higher trophic level consumers in natural ecosystems is still relatively unknown. This study provides an overview of microplastic transport pathways, ecotoxicology, food web transfer, and examples of toxic pollutants sorbed onto microplastics in aquatic food webs, aiming to guide future research priorities in understanding microplastic toxicity through aquatic food webs.

Summary: This systematic review evaluated the efficacy and safety of using potential drugs, remdesivir and glucocorticoid, in treating children and adolescents with COVID-19, as well as using intravenous immunoglobulin (IVIG) in treating MIS-C. The included studies showed that remdesivir may cause adverse events and death, while glucocorticoids were associated with mortality and mechanical ventilation rate. IVIG combined with methylprednisolone had better clinical efficacy for MIS-C patients with severe symptoms. The current evidence is of low quality, and high-quality randomized controlled trials are recommended to provide substantial evidence for guidelines development.

Summary: The type and dose of disinfectants affect the formation of MnOx deposits in pipes. Chlorination leads to MnOx accumulation, while chloramination has almost no accumulation. Low dose of free chlorine also reduces Mn deposit formation. Biotic Mn(II) oxidation occurs when disinfection is discontinued, and it is inhibited again when disinfection is resumed.

Summary: This study investigated the water quality changes in UIP section reactors under different initial chlorine dosages. The results showed that chlorine disappeared rapidly in the UIP. Water with higher initial chlorine had higher turbidity in a short time, but for a longer retention time, the highest turbidity was observed in the iron pipe without initial chlorine. Furthermore, an increase in adenosine triphosphate and heterotrophic plate count was observed with the increase of initial chlorine. Polysaccharide and protein levels also increased with the increase of initial chlorine, promoting the formation of a protective layer to inhibit corrosion.

Summary: Iron particles are a key factor in the discoloration of drinking water distribution systems (DWDS), but their mechanism in the accumulation of trace organic pollutants in DWDS is unclear. This study investigated the accumulation mechanisms of perfluorooctanoic acid (PFOA) using iron-based pipes from a real DWDS. Results showed that old unlined pipes had a higher capacity for PFOA accumulation than new pipes. Among the corrosion products in old pipes, Fe2O3 and Fe3O4 showed no significant accumulation, while FeOOH had a strong accumulation effect for PFOA. In-situ formed iron particles contributed more to PFOA accumulation, and PFOA caused an increase in turbidity and particle size of in-situ formed iron particles.

Summary: Blending of water from different water treatment plants (WTPs) is common in cities, but its impact on iron release in drinking water distribution systems (DWDSs) is not well understood. This study identified water blending areas in a metropolitan city by tracking sulfate and strontium concentration changes. The areas with similar concentration to a specific WTP were categorized as minimum blending areas, while areas with varying concentrations were identified as blending areas from multiple WTPs. The study also found that areas with frequent blending of groundwater and surface water had more iron release, and residual iron in finished water contributed to the elevated iron concentration in DWDSs.

Summary: The study found that perfluorooctanoic acid (PFOA) significantly increased the generation of disinfection byproducts (DBPs) in unlined iron pipes (UIPs), not through its reaction with free chlorine, but through the formation of Fe-PFOA complex. PFOA enhanced iron release from UIPs and was incorporated into iron particles to form the complex, which generated center dot OH that broke down large organic matter into small molecules reacting with chlorine. Precursors with aromatic structures favored the formation of aromatic DBPs through Fe-pi interactions with Fe-PFOA complex. Cytotoxicity tests revealed that DBPs from UIPs with 100 ng/L PFOA had a viability of 46.9%, while that without PFOA had a viability of 67.91%.
