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: 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: Benzo[a]pyrene (B[a]P) is a representative polycyclic aromatic hydrocarbon (PAH) that is commonly found in the environment and human surroundings. It has been shown to have toxic effects on DNA, reproduction, neurology, and development. The metabolism of B[a]P is mediated by cytochrome P450 (CYP P450) and its polymorphism determines the sensitivity to B[a]P. Additionally, B[a]P may facilitate the replication of viruses.

Summary: The majority of experimental studies on the effects of pollutants on meiofauna have been conducted in closed systems, with the current study revealing that single PAHs impact meiobenthic nematodes similarly in closed or open systems, with higher toxicity observed for benzo[a]pyrene. Closed systems contaminated with PAHs became organically enriched, resulting in changes in the types and numbers of deposit feeders. The responses of taxa to hydrocarbons in open systems were influenced by caudal morphology, with the effects of PAHs mixtures being both additive and synergistic. Based on this study, open systems are preferred over closed systems for more accurate research outcomes.

Summary: In this study, a BaP-degrading strain Pannonibacter sp. JPA3 was isolated from oil well production water, which could remove 80% of BaP at an initial concentration of 100 mg L-1 after 35 days of culture. The metabolites BaP-4,5-dihydrodiol, BaP-4,5-epoxide, 5-hydroxychrysene, and 2-hydroxy-1-naphthoic acid were identified in the biodegradation process. A dioxygenase model was built and molecular docking was performed to investigate the interaction mechanism between BaP and dioxygenase. A hypothesis for the progressive degradation mechanism of BaP by this strain was proposed based on the identification of downstream metabolites. In conclusion, this study provided an efficient BaP degrader and a comprehensive reference for the study of degradation mechanisms at the molecular level.

Summary: BaP exposure during the prepubertal period negatively impacted the reproductive parameters in adult male rats, leading to compromised copulatory behavior, reduced sperm quality and quantity, and histopathological changes in testicular tissue. A comprehensive risk assessment of prepubertal BaP exposure is necessary to understand its long-term effects on male reproductive health.

Summary: Hydrophobic organic soil contaminants like PAH are poorly mobile in soil and filamentous fungi are efficient in degrading them, but the mechanism of their mobilization needs further investigation. A microfluidic device was designed to study the uptake of BaP by fungi, revealing the uptake and storage mechanisms as well as the release of surface-active compounds.

Summary: The study investigated the occurrence of PFAS in three seabird species in South Western France, finding that the birds were exposed to levels comparable to highly contaminated species from other geographical areas. PFAS were negatively associated with the body condition of two studied species, with results being sex-dependent. For the great black-backed gull, a positive association was found between exposure to PFAS and TT3, suggesting a potential disrupting mechanism of PFAS exposure.

Summary: The extensive use of pesticides in agriculture has caused contamination of the environment, particularly the atmosphere. This study monitored 36 pesticides commonly used in viticulture in the ambient air using polyurethane foams as passive air samplers. The results showed clear seasonal trends in pesticide concentrations, with the highest levels recorded during their application period. These findings provide preliminary information on the seasonality of pesticide concentrations in vineyard areas.

Summary: In this study, atmospheric organic vapors were measured using a Vocus PTR-TOF in the Landes forest in southern France and the boreal forest in southern Finland, identifying various emission sources and oxidation processes with a high similarity between the two sites. Monoterpenes dominate the biogenic VOCs in both forests, with different oxidation products showing varying degrees of oxidation. Strong relative humidity dependence was found for sesquiterpene lightly oxidized compounds, contrasting with the behavior of monoterpene oxidation products.

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.
