Summary: Couch PUF can absorb many SVOCs and may be an important reservoir for some SVOCs, but it may not be an effective passive sampling medium for those with relatively high Koa values. Direct dermal contact with couch seats may be an important exposure route for non-users of skin-applied compounds.

Summary: Polyurethane foam is often used for sampling semi-volatile organic compounds in the gas phase. The uncertainty of unbiased log K-PUF/G values may exceed 0.2 log units, leading to uncertainties in passive air sampling rates and breakthrough volumes during active air sampling that cannot be less than around 50%.

Summary: The research aimed to obtain two new eco-polyols based on waste polylactide (PLA) and tested their effects on rigid polyurethane and polyisocyanurate foams. Analysis showed that partial replacement of petrochemical polyol by eco-polyols resulted in better performance in terms of density, compressive strength, brittleness, water absorption, and aging resistance for both RPU/PIR and PRU foams.

Summary: Polyurethanes (PUs) are synthesized materials commonly made from isocyanates, diols, and water. Water plays a crucial role in the production of carbon dioxide (CO2) used for self-blowing of the foams. To address safety concerns, researchers have explored alternative chemistries, and cyclic carbonate systems have shown great promise. In a recent study, Bourguignon, Grignard, and Detrembleur demonstrated that a cyclic carbonate and diamine system can generate CO2 for self-blowing through hydrolysis, allowing for a wide range of physical and thermo-mechanical properties. This work represents a significant advancement towards safer and more environmentally friendly PUs.

Summary: Foam-like materials with large specific surface area and complex structure promote flow turbulence and are useful for heat transfer. This study experimentally investigated the hydraulic and heat transfer characteristics of polyurethane foam inserts in a rectangular channel, showing that although the heat transfer intensity of PUF samples is lower than that of metal foams, a significant heat transfer enhancement up to 7 times can still be achieved compared to an empty channel.

Summary: The increasing demand for drugs and the aging population result in a large amount of unwanted pharmaceuticals in households, which can lead to ecosystem pollution when disposed of improperly. The COVID-19 pandemic has worsened this issue due to excessive prescription and panic buying. Informing people, using machine-readable codes, and applying existing techniques can help reduce pharmaceutical waste. A new strategy of online submission and recycling can promote the recovery of active pharmaceutical ingredients and reuse of medicines.

Summary: Efficient transformation of Fe(III) to Fe(II) enhances the efficiency of persulfate-based Fenton-like processes. In this study, a novel heterogeneous Fenton-like system driven by visible light was developed for effective reduction of Fe(III), activation of PS, and degradation of organic pollutants. The system showed higher efficiency and broader pH range compared to traditional systems. Through comprehensive mechanistic study, it was found that the system had sustainable and excellent catalytic performance. The results of cycling experiments and tests involving real industrial wastewater confirmed the enormous potential of the proposed system in environmental remediation.

Summary: About one tenth of humans are impacted by water shortages around the globe, worsened by climate change-induced weather extremes. China has battled with water shortages and floods for decades and developed the concept of sponge cities in the early 2010s to mitigate these issues. Sponge cities integrate natural, green infrastructure into urban drainage systems to absorb, store, and purify rainwater. Several case studies in China demonstrate the potential of sponge cities for green urbanization and ecological restoration.

Summary: Policies and measures to control pandemics often fail, as the environmental drivers of transmission and infection are not well understood. This review explores the effects of atmospheric particulate properties, vortex zones, and air pollution on virus survivability and transmission. Factors such as particle size, chemical constituents, electrostatic charges, and moisture content of airborne particles have notable effects on virus transmission. Additionally, vortex zones and human thermal plumes greatly influence the aerodynamics of airborne particles, impacting virus transport. Understanding these factors may explain the positive correlations between COVID-19 infection and mortality with air pollution.

Summary: This paper reviews and discusses state-of-the-art microbial electrochemical technologies (METs) for resource recovery from wastewater, with a focus on microbial fuel cells (MFCs), microbial electrolysis cells (MECs), and microbial recycling cells (MRCs). MRCs show the greatest potential for simultaneous nutrient recovery and efficient mineral recovery at a larger scale. METs are effective in energy conversion but face limitations and challenges. Future research should consider material lifespan, reduction of secondary pollutants, and scaled-up benchmark systems.

Summary: Despite mass vaccination, lockdowns, and other measures, the transmission of COVID-19 continues. This is due to our limited understanding of droplet transport and viral transmission dynamics. This review explores the effects of various factors, such as droplet size, environmental conditions, virus mutation, and non-volatile components, on droplet evaporation and dispersion, as well as on virus stability. Experimental and computational methods for analyzing droplet transport are presented, along with controlling factors such as environmental conditions, turbulence, ventilation, and droplet size distribution. Results indicate that relative humidity and temperature play a significant role in droplet behavior and virus viability.

Summary: Since the outbreak of the novel coronavirus disease in late 2019, almost 650 million people have been infected worldwide, with over 6.6 million deaths. Despite effectively controlling the first wave of infections in mainland China, with no domestic cases for 56 consecutive days since April 16, 2020, new outbreaks emerged in multiple Chinese cities after cases were found in the Xinfadi Market in Beijing on June 11, 2020. Epidemiological investigations revealed that more than twenty re-emergent outbreaks were caused by fomite transmission via imported frozen and chilled foods contaminated with the SARS-CoV-2 virus. To address this, China established a traceable cold-chain food system and reinforced customs inspections as emergency responses.

Summary: The COVID-19 pandemic has increased the use of synthetic chemical drugs globally, resulting in the release of active pharmaceutical ingredients (APIs) and their metabolites into the environment. While the discharge of these substances into aquatic environments has been widely discussed, the impact on the terrestrial environment through the disposal of sewage sludge has been overlooked. This article highlights the importance of properly treating and disposing of sewage sludge to prevent the release of pharmaceutical compounds and their metabolites into the terrestrial environment, especially during epidemic or pandemic scenarios.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
