Summary: A novel analytical methodology for the extraction and determination of polycyclic aromatic hydrocarbon derivatives in bee honey samples was developed. The method was found to be straightforward, sustainable, and low-cost. The results showed higher levels of nitro- and oxy-PAHs in honey samples compared to unsubstituted PAHs, highlighting the need for routine control and concern regarding the transfer of contaminants in the food chain.

Summary: Understanding the potential source and ecological risk of polycyclic aromatic compounds (PACs) in lakes is crucial for the safety of the aquatic environment. Sedimentary samples were collected from Lake Taihu, China, and analyzed for various PACs. The distribution of PACs in sediments was influenced by economic development, transportation, and organic carbon content. The integrated approach of diagnostic ratios, principal component analysis-multiple linear regression (PCA-MLR), and positive matrix factorization (PMF) was used to identify the sources of PACs.

Summary: This study investigated the atmospheric absorption spectra of PAHs, OPAHs, and NPAHs over the Chinese megacity of Xi'an, showing that they have a significant contribution to radiative forcing by absorbing light in the UVA and (sub)visible region of the spectrum. Seasonal variation was observed in the intensity of light absorption, while the shape of the absorption spectra remained relatively stable. PAHs and carbonyl-OPAHs were found to be the major contributors to light absorption, with certain specific compounds highlighted as potentially problematic for radiative forcing over Xi'an.

Summary: This study investigates the thermochemistry of OPAH species and relevant radicals using quantum-chemical calculations. Thermochemical properties for C 5 -C 18 OPAHs were determined at different temperatures, and a accurate thermochemistry database for OPAHs was developed. The existing group additivity method does not apply to OPAHs, and new group additivity values were obtained for larger OPAHs. These thermodynamic properties and group additivity values are crucial for accurate kinetic models for OPAH formation chemistry and emission control.

Summary: A rapid and efficient method using alkyl-functionalized magnetic nanoparticles-based extraction technique combined with Ultra-High Performance Liquid Chromatography was developed for detecting trace amounts of polycyclic aromatic hydrocarbons in tea leaves. The C-18-alkyl coating was found to be effective in separating polycyclic aromatic hydrocarbons. The magnetism of the nanomaterials accelerated the extraction process while their high surface ratio enabled desirable dispersity in the sample matrix. Moreover, the adsorbents can be washed and reused 30 times without compromising recovery, greatly reducing the budget.

Summary: This study evaluates the effect of oxygenated biomass fuels (biodiesel and ethanol) on PAHs and soot particles during diesel combustion. It is found that both biodiesel and ethanol reduce the concentration of PAHs by inhibiting their production and promoting their oxidation. Ethanol has a stronger inhibitory effect on pyrene. Blending oxygenated biomass fuels increases the oxidation activity of soot particles, leading to a reduction in the amount of soot generated by diesel combustion.

Summary: Oxygenated polycyclic aromatic hydrocarbons (OPAHs) are polycyclic aromatic hydrocarbons (PAHs) with at least one carbonyl group, generally considered more toxic. Different compounds within OPAHs exhibit varied toxicities in food. OPAH and PAH concentrations are positively correlated in many foods, but not in grilled foods and seafood.

Summary: In this study, the risk of endocrine disruption caused by polycyclic aromatic compounds, particularly oxygenated and nitrated polycyclic aromatic hydrocarbons (oxy-PAHs and nitro-PAHs), was investigated. The antiandrogenic and estrogenic activities of 27 compounds, including oxy-PAHs and nitro-PAHs, were determined using CALUX assays. The results showed that certain oxy-PAHs exhibited potent inhibition of AR activation, while all nitro-PAHs showed high antiandrogenic activities. Two oxy-PAHs demonstrated prominent estrogenic activity. Understanding the effects of polycyclic aromatic compounds on endocrine dysfunctions in mammals and aquatic organisms, mediated by AR and ER, remains a challenge.

Summary: The uptake of acetic acid on natural Gobi dust was investigated under different levels of relative humidity. Acetic acid was found to compete with water molecules for adsorption sites on Gobi dust, and its uptake decreased with increasing humidity. Interestingly, at high humidity levels, the uptake of acetic acid led to the formation of oxygenated volatile organic compounds. This study highlights the reactivity of acetic acid on natural mineral dust, and its potential contribution to atmospheric processes.

Summary: The wide range of sources and complex transformation processes of aerosol particles result in strong spatial and temporal variability in their physical, chemical, and optical properties. Accurate representation of these properties is crucial for assessing their impacts, particularly on climate. This study investigates aerosol optical properties and their correlation with fine particle chemical composition in Northern France, using a multi-annual in situ dataset. The findings reveal the significant contributions of ammonium nitrate and organics, highlighting the need for site-specific values to accurately assess the impact of different aerosol species on extinction. The study emphasizes the importance of combined aerosol chemical and physical observations to better estimate their role in climate change and reduce uncertainties in future scenarios based on mitigation strategies.

Summary: This study analyzed the variability and sources of equivalent black carbon (eBC) mass concentrations in urban Europe, emphasizing the need for harmonization of eBC measurements. The results showed a decreasing trend of eBC mass concentrations from traffic sites to urban background sites to suburban sites to regional background sites. There was also a clear decreasing trend in eBC concentrations from Southern to Northern Europe. Furthermore, the study revealed significant spatiotemporal heterogeneity in eBC concentrations and variable contributions of different pollution sources.

Summary: This study examined the environmental factors influencing the formation of ultrafine particles (UFPs) in the urban atmosphere of Lille, France. The results showed that high temperature, low relative humidity, and high solar radiation were ideal conditions for observing new particle formation (NPF) events. The particle growth rate was positively correlated with temperature, and NPF events had a significant contribution to particle number concentration, especially during summer.

The results showed that well-maintained instruments have relatively small unit-to-unit variability in measuring particle light absorbing measurements. It is important to follow maintenance guidelines and use the proper filter tape to ensure high quality and comparable black carbon measurements among international observational networks.
