Summary: This study investigated the deposition fluxes and sources of polycyclic aromatic hydrocarbons (PAHs) in Shanghai. The results showed that the PAHs deposition flux was highest in winter, mainly due to local emissions and transport of pollutants from northern China. The industrial areas had higher PAHs deposition fluxes compared to the city center and agricultural area. The composition of PAHs deposition varied among seasons, with winter and spring samples showing more homogeneity. Positive matrix factorization model identified coal combustion, petroleum volatilization, biomass burning, and vehicle emissions as the main sources of PAHs in specific functional areas.

Summary: This study provides a comprehensive understanding of the concentrations, seasonal variation, spatial distribution, sources, and land-based inputs of polycyclic aromatic hydrocarbons (PAHs) in surface seawater from Zhanjiang Bay (ZJB). The PAHs were found to be ubiquitous but at relatively low concentrations. Seasonal trends and spatial distributions were observed. The PAHs mainly originated from coal/biomass burning, and petroleum and its combustion played an important role in the wet seasons. Land-based inputs of PAHs showed similar characteristics to those in ZJB seawater in terms of seasonal variations, spatial distributions, sources, and composition profiles. The study concludes that PAHs in ZJB seawater are greatly influenced by land-based inputs, atmospheric deposition, and human activities.

Summary: This study investigated the effects of seasonal variation on bacterial communities and polycyclic aromatic hydrocarbon (PAH) bioaccumulation in the Pearl River Estuary. The results showed a negative correlation between PAH concentrations and seasonal variation in temperature. Bacteria taxa related to the degradation of low molecular weight PAHs (LMW-PAHs) played a role in the biodegradation and subsequent bioaccumulation of high molecular weight PAHs (HMW-PAHs) in fishery species. These findings highlight the importance of seasonal variation in the bioaccumulation of PAHs and the ecological risk they pose.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: Determining secular changes in seawater temperature and Mg/Ca ratio is important in various paleo studies. In brachiopod shells, Mg/Ca is used to reconstruct historical temperature changes, but studies show a weak relationship between Mg/Ca and δ18 O and a positive correlation between Mg/Ca and Sr/Ca. The relation between growth lines and Mg/Ca fluctuation is not properly understood. This study analyzes intra-shell variation in Mg/Ca, S/Ca, and Sr/Ca in brachiopod shells and finds that Mg/Ca enrichment is closely associated with growth reduction and not simply seawater temperature changes.

Summary: This study investigates the inter-seasonal distribution and variability of thirteen native PAHs on respirable PM2.5 particles in a coastal-urban region of northern Poland in 2019. The results show clear seasonal differences in PAH concentrations, with the highest levels observed in winter due to coal combustion. High molecular weight PAHs during summer were mainly attributed to vehicle emissions and the petrochemical industry, while low mass contribution of 4-ring congeners was due to photochemical processing. The analysis also indicates significant correlations between meteorological parameters, gaseous precursors, and PAHs, suggesting local/regional primary emission.

Summary: Atmospheric polycyclic aromatic hydrocarbons (PAHs) are at high levels in India, primarily due to biomass burning and coal combustion. This study used the CMAQ model to predict PAH concentrations in different seasons and estimated their sources and health risks. Urban areas had higher health risks, and India had higher PAH levels compared to the US but lower than China.

Summary: The formation of coordination complexes depends on the coordinating ability, but it can be influenced by environmental reaction parameters. The coordinating ability of yttrium shows different patterns in a H2O-rich solvent environment and a DMF-rich solvent environment. By controlling the solvent environment, different yttrium-based metal-organic frameworks can be obtained.

Summary: The simultaneous study of different pollutants in PM2.5 provided valuable information about the pollution sources in the Metropolitan Zone of Mexico Valley. The main sources include vehicle emissions, resuspension of geogenic material, evaporation from petrogenic sources, and emissions from the oil refining industry. The industrial area in the northeast showed the highest concentrations of PAHs and metals, mainly due to diesel vehicles and proximity to agricultural lands. Decision-makers can use these findings to develop targeted control strategies.

Summary: During the lockdown induced by the COVID-19 pandemic in Novi Sad, changes in air pollution were not significant, but there was a reduction in PM2.5 levels and a more uniform profile due to decreased traffic and industrial activities. Additionally, pollutants like NO2, NO, and NOX showed lower levels throughout the day, while CO levels mainly decreased at night.

Summary: This study proposes a novel statistical model based on a two-layer contact and information graph to investigate the impact of disease prevalence on voluntary general population vaccination during the COVID-19 outbreak. Results show that the type of disease information significantly influences individual vaccination decisions, with globally or locally broadcasted disease information having different impacts on vaccination. Additionally, prioritizing elderly population vaccination may lead to an increase in infected cases and a reduction in mortality.

Summary: Heritage buildings are challenged in terms of energy efficiency and indoor/outdoor environment quality. This study assesses the feasibility of using air-to-water heat pumps based on renewable energy sources to preserve historic values and meet energy efficiency and decarbonization goals. The use of Building Information Modelling accurately determines energy demand and selects a heating system for heritage buildings. The analysis compares different heat pump systems and shows that the proposed retrofit scenario reduces energy demand, improves thermal comfort, and cuts emissions.

Summary: This study investigates the common use of perforated plates in gas flow control in wide-angle diffusers of electrostatic precipitators. Previous studies have mainly focused on the effects of the geometric characteristics of the perforated plate when the incoming flow is perpendicular to the plate and the plate covers the entire cross-section of the channel. This work numerically investigates the influence of plate position on flow in a rectangular channel, modeling the perforated plates as thin porous media using the directional loss model.

Summary: The study shows that the non-ionizing field near a fusion reactor has a high growth rate, with commercial surge arresters and flexible models achieving efficiencies of around 20% and slightly less than 40% respectively. It suggests that essential electronics near a fusion generator must be protected, as the environment around such reactors is heavily contaminated with non-ionizing radiation. Commercial surge voltages are isolated for testing as protection against fast overvoltages is critical for the functioning of modern electronics.
