Summary: This study evaluated the bioaccumulation and depuration of TiO2 nanoparticles (TiO(2)NPs) in zebrafish using single-particle ICP-MS (spICP-MS) analysis. The results showed that enzymatic digestion without excessive heating or H2O2 can successfully recover TiO2NP mass and number concentrations from fish tissue. The OECD Test Guideline 305 (OECD TG305) can be used to assess the bioaccumulation and depuration of TiO(2)NPs in fish. The traditional mass concentration metric may be applicable for representing the bioaccumulation potential of chemically inert NPs like TiO2.

Summary: Self-cleaning membranes of ionic liquid-grafted poly(vinylidene fluoride) (PVDF) polydopamine-coated TiO2 were prepared through a nonsolvent-induced phase separation method. The combination of PDA, TiO2@PDA core-shell particles, and hydrophilic IL improved the hydrophilicity of PVDF membranes, significantly increasing water permeation flux and dye wastewater flux. Additionally, the positively charged IL and viscous PDA shell layer enhanced dye retention and adsorption, while the hydrophilic PDA and dopamine promoted UV-catalytic degradation of dyes on the membrane surface, leading to high degradation rates. This technology provides an attractive potential for efficient and easy-to-operate wastewater treatment.

Summary: This study aims to design an efficient adsorbent for high-efficiency removal of elemental mercury (Hg0) from coal-fired power plant emissions. By co-implanting porous TiO2 with inorganic-organic dual functional sites (-SH and MnOx), the 2SH-MnOx/TiO2 adsorbent achieved a Hg0 removal efficiency of 90% at 175 degrees C and a high gas hourly space velocity (GHSV) of 120,000 h-1. The co-existence of -SH and MnOx was found to promote Hg0 adsorption and enhance the transfer of electrons from Hg0 to the adsorbent surface.

Summary: This study investigated the adsorption and aggregation of ferrihydrite nanoparticles (FNPs) in the presence of co-existing hexavalent chromium (Cr(VI)) and norfloxacin (NOR). The results showed that the co-existence of Cr(VI) and NOR increased their adsorption onto FNPs synergistically, and Cr(VI) accelerated the aggregation of FNPs while NOR stabilized them. The aggregation state of FNPs in the presence of Cr(VI) and NOR depends on their ratio.

Summary: The detection of SARS-CoV-2 in wastewater is mainly done through viral concentration methods followed by RT-qPCR testing, which shows varying virus recovery rates. It is recommended to use RT-qPCR or RT-ddPCR targeting specific genes to calculate the limit of detection in wastewater samples for more accurate results. Rigorous methodology is needed to identify positive cases in a region based on genomic copies in wastewater.

Summary: Wastewater-based epidemiology is an effective and cost-effective method for monitoring the spread of SARS-CoV-2, providing early warning of outbreaks in the population. The study found a correlation between viral load in wastewater and clinical cases, with wastewater surveillance able to provide a 2-7 day early warning. The detection rate of SARS-CoV-2 in wastewater was relatively low, with one detection for every 14,300 reported new cases. Prevalence estimates during the study period ranged from 0.02% to 4.6%. The application of wastewater-based epidemiology for COVID-19 surveillance is generally consistent and feasible, with room for improvement.

Summary: Ferrofluids are colloidal suspensions of iron oxide nanoparticles within liquids that have strong magnetic properties. This review discusses the synthesis methods of nanoparticles, surfactants, and carrier liquids for ferrofluid production, as well as the applications of ferrofluids in medicine, water treatment, and mechanical engineering. Coprecipitation and thermal decomposition are the main methods used for synthesizing iron oxide nanoparticles. The selection of surfactants and carrier liquids depends on the desired stability and compatibility of the ferrofluid. Ferrofluids have a wide range of applications, including biosensing, medical imaging, water treatment, energy harvesting, and vibration control.

Summary: The aim of this study was to evaluate the nitrogen removal by hybrid hydrogels containing a consortium of microalgae-nitrifying bacteria, in the presence of activated carbon as an adsorbent. The results showed that hydrogels can carry out the nitrification process without the need for activated carbon to remove potential inhibitors. The best performance was observed for the hydrogel with 5% of biomass without activated carbon, with a nitrification rate of 0.43 mg N/gTSS·h.

Summary: Quantitative monitoring of engineered, natural, or incidental nanoparticles (NPs) is crucial to understand their environmental and ecotoxicological implications. A fast and simple protocol for full quantitative multi-element analysis of metallic or metal-containing NPs in wastewater and sludge samples via single-particle ICP-MS was developed. The efficiency of removal of NPs throughout the WWTP was significantly dependent on the type of metal-containing particles and the influent concentration.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
