Summary: East Asia has the highest emissions of SO2 and NO (x) in the world. This study examines the long-range transport of acidic pollutants in the region, specifically focusing on the impact of emissions from eastern China on Taiwan, Japan, and Korea. The results show that despite a decrease in local emissions, there is no decreasing trend in the annual deposition of non-sea-salt sulfate in northern Taiwan. However, there is a significant decreasing trend in the summer deposition of sulfate and nitrate.

Summary: The uncertainty in the quantitative estimates of long-range transport of pollutants in air quality models is large. This study aims to assess the impact of uncertainties in input parameters on the model estimates using the GNAQPMS-SM model and Latin hypercube sampling method. The uncertainties of input parameters are reasonably quantified and the multiple linear regression method is used to fit ensemble simulation results, providing more accurate estimates of pollutant transport.

Summary: The relationships between meteorological parameters and air pollutants were evaluated in this study. The results showed that meteorology significantly influenced the diffusion and dispersion of air contaminants. Temperature had the strongest negative impact on pollutant concentration, while other meteorological parameters had both negative and positive influences. The interaction between pollutants and relative humidity and wind speed involved a two-way process. The study also highlighted the impact of rainfall on both particulate matters and gaseous pollutants.

Summary: This study shows that electrolytes driven by an external electric field exhibit scale invariance despite Debye screening. Long-range correlations result in a Casimir-like fluctuation-induced force between neutral boundaries that can be controlled by the electric field, behaving differently from other fluctuation-induced forces.

Summary: The study examines the dispersion of microplastics in the atmosphere, indicating that long-range transport plays a major role in their motion and pollution in remote areas. The Lagrangian particle dispersion model MILORD was used in the backward mode to identify possible sources of microplastic pollution in a remote site. The results reveal that microplastics can travel up to 100 km and the contribution from local sources is minimal.

Summary: Van der Waals heterostructures exhibit unique electronic properties and have been studied using nonlocal measurements. Graphene edges with charge accumulation are found to produce giant nonlocal effects, supporting long-range currents. Edge conductance affects current flow in moderate magnetic fields, leading to decoupling between edge and bulk transport. The observed exotic flow patterns are sensitive to edge disorder and can flow against the global electric field. Thus, edge transport in charge-neutral graphene can explain various nonlocal transport measurements.

Summary: By introducing tortoise coordinates, long-range potential scattering is transformed into short-range potential scattering, allowing long-range potential scattering to be treated similarly to short-range potential scattering. The scattering wave function for long-range potential scattering is represented by tortoise coordinates and scattering phase shifts. This approach is not limited to scattering but also extends to bound states.

Summary: This study reveals that a one-dimensional ordered fermionic lattice system connected to two baths with different chemical potentials at zero temperature exhibits two phases of subdiffusive conductance scaling with system size, unlike the perfectly ballistic transport in the isolated system. Interestingly, there are two chemical-potential-driven subdiffusive to ballistic phase transitions at zero temperature in the open system scenario.

Summary: This article suggests that the safe operating space of the planetary boundary for novel entities is exceeded due to the increasing production and releases exceeding the global capacity for assessment and monitoring. Plastic pollution is highlighted as a major concern. The article presents an impact pathway from the production of novel entities to their impacts on Earth system processes and proposes several criteria for control variables. Urgent action is recommended to reduce the harm associated with exceeding the boundary by reducing the production and releases of novel entities.

Summary: The study aimed to estimate the marginal effect of liver fluke infection on productivity of Scottish beef cattle and the associated greenhouse gas emissions intensity. The researchers analyzed abattoir records from 2014 to 2017 in Scotland to determine the presence or absence of liver fluke lesions in the liver at the time of slaughter. Causal inference methods, such as directed acyclic graphs and inverse probability weighting, were used to estimate the marginal effects of liver fluke on cattle growth and days to slaughter. Comparison with linear mixed effects models showed similar results, and calculations of greenhouse gas emissions indicated a lower emissions intensity in herds without liver fluke. The study suggests that sustainably controlling liver fluke could have significant production and environmental benefits.

The regulatory approaches for polymers need to catch up with scientific advances. Transparency, environmental fate, hazards, and production patterns are key aspects that require attention in polymer regulation for a toxic-free and sustainable circular economy.

Summary: Soil carbon sequestration (SCS) practices on French agricultural land are important for climate change mitigation and the success of France's 4 per 1,000 initiative. A survey of 506 French winegrowers was conducted to assess the adoption rate of SCS practices in vineyards, identify motivations and barriers to adoption, and explore ways to overcome these barriers. The survey revealed differences in motivations and barriers for different SCS practices, highlighting the need for improved communication and targeted policy incentives.

Summary: The threat posed by plastic in the environment is not well understood due to uncertainties about its sources, transport, transformation, and removal processes, as well as the properties of the plastic pollution itself. Plastic creates various particulate pollution with different compositions, sizes, and shapes, accompanied by chemicals. This Perspective suggests using process-based mass-balance models to synthesize knowledge about plastic pollution based on its measurable properties. Addressing environmental plastic pollution is challenging due to its complex and diverse physical and chemical properties. This Perspective argues that process-based mass-balance models can provide a viable solution for evaluating environmental exposure to plastic pollution.

Summary: Unconventional oil and natural gas development (UOGD) in the United States has expanded rapidly in recent decades, raising concerns about its impact on air quality. This study conducted extensive air monitoring during the development of several large well pads in Broomfield, Colorado, providing a unique opportunity to examine changes in local air toxics and VOC concentrations during well drilling and completions and production. The study identified significant increases in VOC concentrations during drilling operations, highlighting the importance of emissions from synthetic drilling mud. The findings suggest opportunities to mitigate emissions during UOGD operations.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
