Summary: This study investigated the effect of humidity on the discharge mode transition in air plasmas generated by surface dielectric barrier discharge. The research found that humidity has a bidirectional effect on the production of O-3 and NO2 in the discharge, indicating its influence on the discharge mode transition. The competition between reaction pathways dominated by N-2(nu) and water-originated compounds may be the cause of this bidirectional effect.

Summary: The rapid urbanization in China has led to increasingly serious air pollution. In this study, observations using Lidar and UAV were conducted in Nanjing during spring to study the vertical distribution and correlation of ozone and particulate matter. The results showed that ozone concentration is highest in the upper boundary layer, while aerosol extinction coefficient decreases with height. Below 650 m, ozone and aerosol are negatively correlated, while above the boundary layer, they are usually positively correlated, regardless of the presence of particulate pollution.

Summary: Despite restrictions, fireworks in Hawaii have caused accidents, noise and air pollution, with hospital admissions for accidents and breathing difficulties. Initial success was seen after the permit requirements were implemented in 2012, but recent years have seen increased air pollution at New Year, likely from fireworks rather than weather conditions. Locally, illegal aerial fireworks are suspected of causing injury and pollution, but estimating the quantity and preventing their import has proved challenging. It is important to enhance understanding of local environmental problems caused by fireworks and improve compliance with regulations without diminishing New Year celebrations.

Summary: The COVID-19 pandemic resulted in notable changes to societies worldwide. Insect monitoring data from 15 museums in and around Vienna between 2018 and 2022 showed changes in insect populations during the lockdown periods, with an increase in silverfish, Tineola bisselliella, and Attagenus sp. during the first lockdown, and no significant changes during the second lockdown. While no damage to museum objects was observed, this emphasizes the need for continued monitoring for potential pest risks even when museums are unoccupied.

Summary: Most stained-glass windows installed during the Middle Ages have deteriorated over time due to climate and pollution. To reconstruct their alteration history over the centuries, evaluate the current environmental risk, and predict their alteration in the future, two modelling methodologies have been used. The first methodology established dose-response functions (DRFs) based on short-term exposure of medieval-type glass in different sites, correlating relevant environmental factors with the response of the material. The second methodology consisted of laboratory experiments to parameterize kinetic laws as a function of specific parameters, which can be extrapolated over long periods.

Summary: The study focused on the agreement between climate model outputs in assessing the magnitude and direction of change of the Scheffer index over continental Africa. Rainfall was found to be crucial in determining the magnitude of the index, and regions with poorly captured rainfall systems showed a large range in projected Scheffer values. To enhance the transferability of the index to tropical regions, the addition of a Scheffer threshold for high risk of deterioration was suggested. Projections of future change in the index were driven by temperature changes rather than rainfall. While there was disagreement in the magnitude of the Scheffer index, models showed good agreement over the direction of change across Equatorial Africa.

Summary: This study examines the local and indoor climate, insects, and fungi in a historic library near Vienna. The research reveals that the library environment is mostly dry and cool, but temperatures and humidity behind cupboards and shelves are slightly higher. Biscuit beetles infestations have been observed in the past decade, but treatment has shifted the dominance to Anthrenus sp. Silverfish are also present, but only in one corner. Fungal outbreaks have occurred, and the types of fungi in the air have changed. While the stable environment at Klosterneuburg is suitable for book preservation, the presence of insects and mold suggests the need for vigilance.

Summary: Fire poses a global problem for traditional villages, particularly those using wood and thatch as materials. Traditional villages on Sumba Island have limited ability to suppress fires due to their remote location and poor accessibility. By analyzing documentary evidence and satellite imagery, the fires on Sumba Island since 2001 have been traced. It has been discovered that the number of dry-season fires correlates with the consecutive dry days, indicating a potential increase in future fires. Efforts are being made to reduce the impact of village fires, but challenges exist due to the significance of architectural heritage and religious context.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
