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: Exposure to atmospheric air pollution containing volatile organic compounds such as PAHs is a risk factor for lung inflammation and lung cancer. miRNAs, small RNA molecules that regulate physiological processes, have been found to be associated with diseases. Studies have shown that environmental pollution exposure can affect the expression regulation of miRNAs.

Summary: The study investigated the influence of geography, climate, and socio-economy on pollutant levels in China. Results showed that regions with higher population and lower GDP tend to have higher levels of PAHs in the atmosphere. Comprehensive measures are needed to reduce pollution and sources of PAHs in heavily polluted areas.

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: This study comprehensively characterized PM10 from residential and traffic-impacted areas in a Portuguese city and investigated its biological effects on lung epithelial cells. The results showed that PM10 extracts could induce cellular toxicity, oxidative stress, mitochondrial damage, and cell cycle arrest, as well as modulate intracellular metabolic processes. Interestingly, PM10 samples rich in toxic substances had a greater impact on cell metabolism.

Summary: Nurdles, pre-production plastic pellets, are a significant source of plastic pollution in marine environments, primarily made of polyethylene and polypropylene with sorbed polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). Heavily weathered nurdles tend to have higher concentrations of organic pollutants, and the bioaccessibility of PAHs is higher in lightly weathered nurdles compared to heavily weathered ones. This study provides valuable insights for toxicity assessment and resource management of plastic debris in coastal environments.

Summary: The objective of this study was to investigate the physicochemical characteristics of PAHs in CPM during fast condensation. The concentration of PAHs increased at lower condensation temperatures, suggesting enhanced conversion of gaseous PAHs to CPM. PAH concentrations increased with the number of rings in the fragment, with high-ring PAHs accounting for a significant proportion of the total concentration and toxic equivalent of PAHs. Additionally, the collection of particulate-phase PAHs was challenging due to the synergistic effect with fine particles and the formation of inorganic particles under ammonia-rich conditions. Morphological and chemical characterization of CPM revealed well-aggregated particles, and the presence of PAHs enhanced the diameter of CPMs. Most of the carbon element was collected in the rinse fluid, indicating that PAHs in CPM were collected through condensation.

Summary: This study measured the oral bioavailability of PAHs in PM10 using a simulated digestive system test, and found that the bioavailability was below 5%, with fluorene, anthracene, acenaphthene, and phenanthrene being the most bioavailable PAHs. Health risk assessment showed no carcinogenic risk from orally bioavailable PM10-bound PAHs.

Summary: The frequent reports of microplastics in fish stomachs have raised societal and environmental concerns as they can accumulate along the food chain. The analysis of microplastics in fish requires addressing two main challenges: sample treatment and final characterization. This study proposes a novel method using a quantum cascade laser-based device for faster characterization, but it also faces challenges in sample processing and particle handling.

Summary: A novel in-vitro method was developed to assess the inhalation bioavailability of metal(oid)s in PM2.5 samples using synthetic body fluids, human physiological conditions, and a simulated air-blood barrier. Metal(oid)s such as Cu and Mo showed the highest bioavailability, while Al, Co, Cr, Fe, Ni, Ti, and Tl had low bioavailability. Health risk assessment suggested no risk to human health based on inhalation exposure scenarios and hazard indexes. The chemical composition of PM2.5 influenced the bioavailability of certain metals.

Summary: In this study, a vortex-assisted liquid-liquid micro-extraction (VALLME) method was developed for extraction and enrichment of total mercury (Hg) from seawater. The method involved derivatisation of Hg with ammonium pyrrolidine dithiocarbamate (APDC) and quantitation by atomic absorption spectrometry (AAS). Variables affecting the derivatisation and VALLME extraction were investigated. The developed method showed high sensitivity and precision, with an enrichment factor of 51 and extraction recovery of 76% when using specific conditions. The method was validated using certified reference materials and applied to assess Hg levels in seawater samples.

Summary: Although the European Parliament has set limits for the environmental quality of organotin compounds (OTs) in Directive 2013/39/EU, the marine environment continues to be affected due to global maritime circulation. OTs accumulate in fish and seafood, making them the main source of OTs in human consumption. A robust and fast method for quantifying OTs in fish and seafood, using ultrasound-assisted extraction and gas chromatography-tandem mass spectrometry, has been validated and applied.

Summary: This study examines the spatio-temporal variations of PM10 mass concentrations and associated pollutants in Medellin and Itagui, Colombia. The study provides valuable data on the chemical characterization of PM10, including metal(oid)s concentrations and polycyclic aromatic hydrocarbons (PAHs) concentrations. The results show that combustion processes and secondary aerosols are the major sources of PM10 in the study area. Additionally, the study reveals a moderate carcinogenic risk from PM10-bound PAHs exposure and a significant carcinogenic risk from carcinogenic metal(oid)s exposure during the sampling period.
