Summary: Testing the innovative and cost-effective Mosspheres as passive air samplers for monitoring and mapping polycyclic aromatic hydrocarbons (PAHs) proved their high sensitivity and suitability. The study detected low concentrations of PAHs, with only a few enriched points exceeding legal thresholds near industrial areas and busy roads. However, Mosspheres were able to detect spatial structure for several PAHs and construct high-resolution pollution maps, supporting their widespread application and potential inclusion in European Directives on air quality control.

Summary: Passive sampling device (PSD) with developmental toxicity assays in zebrafish can effectively detect the whole mixture toxicity of bioavailable non-polar organics in environmental sites. By incorporating RNA-Seq, this study investigated the toxicity of PSD extracts from two locations in Portland Harbor Superfund Site on zebrafish embryos. The results showed that RM 6.5W had higher concentrations of PAHs and exhibited higher toxicity, while the gene expression profiles were similar between the two extracts.

Summary: The concentrations of legacy and currently emitted organic pollutants were analyzed in the water from six high-mountain lakes in the Pyrenees. Passive water sampling using LDPE and SR sheets was conducted over a three-year period between 2017 and 2020. The results showed that HCB concentrations remained the same as those measured two decades ago, while PAHs concentrations were reduced by half. PCB concentrations were lower, but variations could be due to differences in sampling methods. OPEs were measured for the first time and found at high concentrations in some sites. The study also revealed the deposition of pollutants from air to water, except for some OPEs and PCBs that reached equilibrium conditions, and HCB with volatilization fluxes. PAHs and OPEs were affected by atmospheric degradation, supporting their diffusive exchange from air to water, while PCBs and organochlorines were not influenced by photodegradation. These remote lakes in the Pyrenees accumulate both emerging and legacy pollutants due to long-range atmospheric transport.

Summary: This study conducted at the Agbogbloshie e-waste site in Accra, Ghana, found that e-waste workers were exposed to higher levels of PM and PAHs compared to a reference population. While there was a weak correlation between PAH concentrations and PM levels, the abundance of PAHs showed a strong and inverse correlation with PM levels, suggesting multiple and different sources of PAHs and PM. Personal and shift samples were crucial for accurately characterizing worker exposure in this setting.

Summary: This study proposed the best PAH and PCB Kp-w values for two commonly used passive sampling materials, low-density polyethylene and polydimethylsiloxane, based on critical assessment of existing literature data and new Kp-w determinations. It was found that Kp-w values for PDMS are independent of source, while Kp-w values for polyethylene differ depending on the source, potentially requiring standardization.

Summary: For decades, the floating catkins produced by willow and poplar trees have been criticized for spreading germs and causing fires. A research project conducted in Harbin, China investigated whether and how willow catkins could adsorb atmospheric polycyclic aromatic hydrocarbons (PAHs). The results revealed that both airborne and ground catkins preferred to adsorb gaseous PAHs rather than particulate PAHs. The removal loading of atmospheric PAHs by catkins in Harbin was estimated to be 1.03 kg/year.

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: This study systematically investigated the levels of particulate matter-bound polycyclic aromatic hydrocarbons (PAHs) and nitro-PAHs (NPAHs) in different areas of Hanoi, Vietnam in winter and summer from 2019 to 2022. The PAHs and NPAHs concentrations showed seasonal variations, with higher levels in winter. Biomass burning was identified as a major source of PAHs and NPAHs, and motor vehicles, especially motorcycles, were dominant in the summer. The study also assessed the cancer risks associated with exposure to PAHs and NPAHs, and found higher risks for females through ingestion and dermal absorption pathways.

Summary: There is significant heterogeneity in smoking prevalence and tobacco control policy across different countries, which may lead to increased passive smoking and adverse health effects among international travelers. This pilot study found that traveling to a city with higher smoking prevalence may increase passive smoking exposure, with pro-oxidative effects partially mediated by polycyclic aromatic hydrocarbons (PAHs).

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: This study investigates the association between exposure to PM2.5 from controlled burning during the DWH disaster and decreased lung function. The results show that workers with higher cumulative PM2.5 exposure have significantly lower forced expiratory volume and forced expiratory volume to forced vital capacity ratio compared to those not involved in burning.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
