Summary: Due to its unique environment and geographic location, Svalbard has been identified as a potential pollution reservoir in the Arctic. This study found the presence of microplastics and polycyclic aromatic hydrocarbons (PAHs). Textile materials and fisheries-related debris were identified as possible sources of microplastics and anthropogenic particles. PAHs in soils were mainly derived from traffic emissions and diesel combustion from a local power plant, while ship emissions were the dominant source of PAHs in sediments. Anthropogenic input was confirmed to be higher in Ny-Alesund, while transportation through ocean currents may contribute to the higher abundance of microplastics in Rijpfjorden.

Summary: This study conducted the first research in 25 years on the least studied and hard-to-reach areas of Siberian Arctic seas. It found that the concentration of polycyclic aromatic hydrocarbons (PAHs) is comparable to the data from the 1990s, indicating a long-term persistence of pollution despite a decline in global PAH emissions. The main sources of PAHs are coal/biomass and liquid fuel combustion.

Summary: Helically twisted conductive nanocarbon materials are suitable for optoelectronic and electromagnetic molecular devices on the nanometer scale, showing a large effective conjugation length and ultrafast decay dynamics. The extended π-helicenes achieved a large effective conjugation length through helical fusion, leading to an absorption edge in the near-infrared region.

Summary: Here, a facile and selective synthesis of cationic azatriphenylene derivatives was achieved through electrochemical intramolecular cyclization, where the key step involves atom-economical C-H pyridination without a transition-metal catalyst or an oxidant. This proposed strategy provides a practical approach for introducing cationic nitrogen (N (+)) into pi-electron systems, thus expanding the molecular design of N (+)-doped polycyclic aromatic hydrocarbons.

Summary: In this study, CeO2-based porous carbonaceous frameworks (CeO2 PCFs) were used as antioxidant nanozymes to scavenge reactive oxygen species and absorb benzo[a]pyrene. CeO2 PCFs exhibited excellent superoxide dismutase-like and catalase-like activity, effectively eliminating superoxide radical, hydroxyl radical, and hydrogen peroxide. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) free radical scavenging assay confirmed the free radical scavenging ability of CeO2 PCFs. Furthermore, CeO2 PCFs with large surface area and porous structure efficiently adsorbed benzo[a]pyrene. The designed CeO2 PCFs can serve as new antioxidant nanozymes for scavenging reactive oxygen species and adsorbing polycyclic aromatic hydrocarbons (PAHs).

Summary: Seabirds in the Arctic are exposed to various environmental contaminants. This study focused on polycyclic aromatic compounds (PACs), which have received less attention compared to other contaminants. The study found that fulmars generally had higher PAC concentrations than murres, and the concentrations of most PAC groups were higher in birds from 2007/08 compared to 2018. The exception was the higher concentrations of alkylated congeners of heterocyclic aromatic compounds in murres from 2018, indicating recent exposure to refined petroleum products.

Summary: In this study, we conducted single-molecule spectroscopy at cryogenic temperatures to investigate the optical properties of graphene quantum dots (GQDs). We found that temperature has an effect on the spectral characteristics of GQDs, and we used density functional theory calculations to explain these observations. Additionally, we discovered that the vibrational features can serve as a unique fingerprint for identifying GQDs.

Summary: Polycyclic aromatic hydrocarbons (PAHs) are organic compounds produced from incomplete combustion, posing health risks to humans; olive oil contains various PAHs, with a high content of low molecular weight PAHs likely influenced by diesel exhaust and biomass combustion; research indicates that diesel exhaust and biomass combustion are major sources of PAHs in olive oil, suggesting air quality may impact pollution levels in olive oil.

Summary: Ecological regime shifts in China's largest lagoon, Lagoon Pinqing, have influenced the contribution of microplastics to the burial of polycyclic aromatic hydrocarbons (PAHs) in sediments. The contribution varied during different periods due to changes in factors such as total phosphorus and total nitrogen. The results suggest that regime shifts can enhance the contribution of microplastics to the burial of PAHs, with the degree of contribution influenced by the specific regime shift.

Summary: The use of passive air samplers (PAS) for semi-volatile organic compounds (SVOCs) has been expanding. A year-long calibration study confirmed that the linear uptake period of a passive air sampler using XAD-resin sorbent is longer than estimated with a simulation model and much longer than those of samplers using polyurethane or polyethylene as sorbents. The sampling rates (SRs) for 26 SVOCs were determined, ranging from 0.1 to 0.6 m(3) day(-1) for SVOCs such as brominated flame retardants, organophosphate esters, and halogenated methoxylated benzenes.

Summary: Some phthalate esters (PAEs), commonly used in consumer products, have been restricted due to their adverse health effects, leading to the emergence of alternative non-phthalate plasticizers (NPPs). This study investigated the presence of PAEs and NPPs in the air of a typical indoor residence in northern China for over a year. It was found that PAEs were still the dominant plasticizers being used, with higher concentrations compared to NPPs. The concentrations of PAEs and NPPs showed seasonal variation, with peak levels occurring in summer and autumn.

Summary: Using a mass balance box model, the historical loading, removal, and cumulative burden of b-hexa-chlorocyclohexane (b-HCH) in the Arctic Ocean from 1945 to 2020 were investigated. The majority of the loading occurred through ocean currents and river inflow, while atmospheric transport contributed only a small portion. b-HCH accumulated in the Arctic Ocean starting in the late 1940s, reached a peak in 1986, and decreased by 2020. The pathways of b-HCH entering the Arctic differed from those of a-HCH, with b-HCH primarily transported through long-range oceanic transport.

Summary: This study demonstrates that even the most volatile PCBs can maintain linear uptake in a passive air sampler using XAD-resin as the sorbent (XAD-PAS). The sampling rates for 66 congeners decrease with the number of chlorines and increase within a homologue with the number of chlorines in the ortho-position. By quantifying the effects of chlorine substitution and temperature on sampling rates, it is possible to estimate the sampling rates for all congeners at any deployment temperature. The XAD-PAS is suitable for unbiased sampling of gaseous PCBs in various settings.

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.
