Summary: PAHs exposure can cause gross morphological abnormalities and cardiotoxicity in developing fish embryos. Changes in cholesterol biosynthetic pathway genes were found, and pretreatment with cholesterol solution partially mitigated the effects on heart rate. Exposure to PAHs also led to an increase in yolk area, indicating impaired lipid transport during development.

Summary: In this study, emissions of FPM, CPM, and PAHs from different stationary coal-fired sources were measured. The results showed that CFB systems installed with dry and semidry FGD systems and SCR/SNCR emit lesser filterable PM but substantially higher CPM. Wet FGD technology in CFB boilers exhibits lower CPM emissions. Various small coal-fired stoves burning different types of coal do not significantly affect CPM but the PAHs emissions. Based on the data of this investigation, an emission inventory of CPM from various stationary coal-fired sources was estimated.

Summary: Measurements of hazardous semi-volatile organic compounds (SVOCs) in fine particulate matter (PM2.5) at Yongxing Island in the South China Sea showed low concentrations of polycyclic aromatic compounds (PACs), largely influenced by Southeast Asian countries and southern China. The atmospheric loss of SVOCs and enhanced formation of N/OPAHs from tropical regions were significant factors for the low PAC concentrations. Enhanced atmospheric reactions and insignificant local sources were further indicated through results and correlation analyses.

Summary: Compared with animal studies, there is limited research on the impairments of T-cell response and exposure-response from particulate matter (PM) and its components in the human population. This study found that PM and its bound polycyclic aromatic hydrocarbons (PAHs) and metals can induce immune impairments by altering T lymphocytes and genes of T-bet and GATA3. Additionally, CD4+ T lymphocytes were found to mediate the associations of PM2.5 with T-bet expression.

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: Pharmaceutical compounds and their metabolites in natural and wastewater have been neglected in terms of their toxic effects on aquatic animals, especially the metabolites. This study investigated the effects of the main metabolites of carbamazepine, venlafaxine, and tramadol on zebrafish embryos. The results showed that some metabolites elicited higher rates of embryonic malformations and significantly decreased larvae responses compared to controls. The expression of several tested genes was found to be affected, and potential biomarkers of exposure for venlafaxine and carbamazepine groups were identified. This study highlights the risk of contamination in aquatic systems and the importance of scrutinizing metabolites by the scientific community.

Summary: The role of serotonin in the phototactic and locomotor behavior of Daphnia magna was examined through genetic and pharmacological approaches. The study found that animals lacking serotonin exhibited increased negative phototaxis and locomotor activity, as well as reduced responses to fish kairomones. Exogenous serotonin restored the phototactic and locomotor behavior of individuals lacking serotonin, but had no effect on the response to fish kairomones. Surprisingly, fluoxetine altered locomotor activity and phototactic behavior in serotonin-deficient individuals, and also increased acethylcholine and GABA concentrations.

Summary: Wastewater Treatment Plant (WWTP) effluents are significant sources of antibiotics, antibiotic resistance genes (ARGs), and resistant bacteria, posing threats to aquatic biota and human health. This study explores the impact of the antibiotic doxycycline on the microbiome of Daphnia magna in lab water and treated wastewater media. The results indicate that doxycycline and the media significantly influence the composition of the Daphnia-associated microbiome, with notable changes in Enterococcus spp. Furthermore, doxycycline reduces the presence of Limnohabitans sp. and impairs Daphnia reproduction in lab water, while treated wastewater increases microbiome diversity, richness, and promotes fecundity. The study also detects various ARG genes, including qnrS1, sul1, and blaTEM, with a higher abundance in treated wastewater compared to lab water.

Summary: This study investigated the sources of PM10 and the impact of atmospheric secondary processes on aerosol particle composition in a high-altitude site in southern Europe during summer 2021. The results identified Saharan dust, advection from the urbanized valley, local combustion, smoke from a fire-event, and aerosol from regional recirculation as the main sources of PM10. The sources of PM were associated with synoptic meteorological conditions and circulation patterns typical of mountainous areas. Despite the identification of a local pollution source, its contribution to PM10, OC, and EC was minimal. The findings highlight the significant influence of long-range transport of anthropogenic aerosols on the aerosol chemical composition at this remote site.
