Summary: This study suggests that co-exposure to PAHs and smoking, along with XPC gene polymorphisms, can increase individual susceptibility to DNA damage. More specifically, base modifications in the KRAS and BRAF exons were positively associated with levels of 1-hydroxypyrene (1-OH-Pyr). Additionally, the effects were more pronounced in individuals carrying specific XPC genotypes. These findings highlight the importance of considering genetic factors in understanding individual responses to environmental exposure.

Summary: 1-Hydroxypyrene (1-OHP), as a metabolite of polycyclic aromatic hydrocarbons (PAHs), is commonly used to assess human exposure to PAHs. A new electrochemical device based on poly(L-glutamic acid)-modified a screen-printed graphene electrode (poly(L-GA)/SPGE) for 1-OHP detection was created. The developed sensor showed a linear detection range of 1-1000 nM with detection and quantification limits of 0.95 and 3.16 nM, respectively. This sensor was successfully applied to determine 1-OHP in human urine samples, providing a valuable tool for early detection of illness risk related to PAHs in the human body.

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: The study revealed a linear dose-effect association between exon damage of EGFR and PAH exposure, with differences in genetic contributions to exon damage. The presence of FEN1rs rs174538 showed modifying effects on the associations of urinary 1-OH-pyr with EGFR-19 and EGFR-21, indicating potential at-risk subpopulations susceptible to adverse health effects induced by PAH exposure.

Summary: The nanocomposite of PAMAM/Cr-MOF/GO showed enhanced electrocatalytic effect on the electrochemical reduction of 1-OHPyr. The synergistic effect from the high porosity of Cr-MOF and high conductivity of ERGO, along with further electron transport action of the nanocomposite, contributed to this enhancement. The constructed electrochemical sensor exhibited good linear relationship in detecting 1-OHPyr, with a low detection limit, suggesting potential wide applications in electrochemical sensing platforms.

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: The study found that the addition of ethanol can increase the concentration of aromatic substances in methane diffusion flames, with the chemical effect being the main factor, followed by the dilution effect and the thermal effect. The increase in pressure accelerates the production of aromatics, as the narrowing of the flames improves air entrainment and significantly speeds up overall reactivity.

Summary: Shenyang, the provincial capital of Liaoning province in China, is heavily polluted due to its high population and heavy machinery manufacturing. This study analyzed the concentrations of nine polycyclic aromatic hydrocarbons (PAHs) and 1-nitropyrene (1NP) in aerosol samples collected in Shenyang from 2014 to 2020. The results showed a decrease in the annual mean concentration of PAHs and 1-NP during this period, attributed to the transition from coal to electric and natural gas heating, upgrades in heating stoves and improved vehicle and fuel standards. Notably, the proportion of 4-ring PAHs increased in summer but decreased in winter from 2014 to 2020. Possible reasons for this difference were identified, such as the use of higher cetane rating fuel in summer and the use of air pollution control devices in winter. Despite the decrease in health risks, the concentrations of PAHs and 1-NP in Shenyang during the winter of 2020 still exceeded national standards, indicating the need for additional environmental regulations to further improve air quality in the city.

Summary: This study investigated the effects of air pollution, land use types, and parental mental health on respiratory symptoms in children aged <2 years in the Greater Taipei area. The results showed that postnatal exposure to PM2.5 and O-3 was positively associated with respiratory symptoms in children. Traffic-related land use types, sports facilities, and commercial land had adverse effects, while the presence of schools in the neighborhood was beneficial. Parental mental health was also associated with children's respiratory symptoms.

Summary: Extreme high temperature poses significant threats to public health. Subjective heat-health symptoms are more direct motivations for heat adaptive behaviours. Age, gender, and health condition are related to the frequency of feeling moody and ill, as well as the use of umbrellas and hats. Biophysical acclimatisation and adaptation of behaviours were found among people frequently working outdoors.

Summary: Increasing surface air temperature due to global warming leads to heat stress, which has potential impacts on human health. This study found a general increase in heat stress over the past decade, with tropical regions experiencing the highest warming. On the urban scale, heat stress may have led to a reduction in labor hours by up to 20% in some Asian cities. The exposure to heat stress is a collective challenge with environmental, economic, and social implications.
