Summary: This study examines the gas-phase retention volume behavior of highly volatile organophosphate esters (OPEs) on polyurethane foam (PUF) using a frontal chromatogram. The results show that vapor penetration depends on the volatility and total air volume, with a negative correlation between the logarithm value of breakthrough volume (VB) and subcooled liquid vapor pressure (PL). The enthalpy differences between OPEs and polycyclic aromatic hydrocarbons (PAHs) suggest different sorption interaction strengths with PUF. The partition coefficients (KPUF-air) of the tested OPEs on PUF are lower than those of PAHs and organochlorines.

Summary: Organophosphate esters (OPEs) were detected at elevated concentrations in the Great Lakes region, particularly chlorinated compounds, with some dependence on temperature. The main sources were likely anthropogenic influence from surrounding rural and urban areas. Nearly all OPEs underwent net gas-phase deposition to the lakes, dominated by TCEP and TCPPs.

Summary: The regional characteristics of atmospheric organophosphate triesters (OPEs) and organophosphate diesters (Di-OPs) were investigated in the Pearl River Delta (PRD) using passive air samplers. OPEs were mainly distributed in the central part of the region, possibly due to the presence of industries related to OPE-containing products. Di-OPs, on the other hand, were scattered throughout the PRD, indicating direct industrial emission from their applications. Lower levels of certain compounds were detected in summer, suggesting partitioning off particles and photo-transformation.

Summary: In this study, a colorimetric ozone passive sampler (OPS) was developed to improve the recognition of average ozone (O3) exposure. By analyzing the colorimetric changes and using the effective absorbance of blue scale, the OPS was optimized and validated. Field tests showed a significant disparity between O3 concentrations and personal O3 exposures, highlighting the importance of assessing health risks. The OPS serves as a useful tool for monitoring O3 exposure levels and raising awareness of invisible indoor hazards.

Summary: This study assessed the personal exposure of nail salon workers in Toronto, Canada to 10 phthalates and 19 organophosphate esters. The results showed significant correlations between the levels of these compounds detected in passive silicone brooches and wristbands and those in active air samplers. Additionally, the higher concentrations of these compounds on the silicone brooches and wristbands suggest that these passive samplers can be used to measure the exposure of nail salon workers.

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: 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: Single-use face masks are a powerful tool for reducing the spread of COVID-19, but the pollution from discarded masks may become an environmental issue. Synthetic antioxidants were detected in single-use face masks, with the highest concentrations found in the middle layers. Both medical and nonmedical face masks showed similar concentrations of antioxidants. This study estimates that 1084 tons of antioxidants are used in face masks annually.

Summary: This study revealed the microbial transformation potential of 6:2 chlorinated polyfluorooctane ether sulfonate (6:2 Cl-PFESA) in anaerobic microbial systems. The compound was reductively dechlorinated to 6:2 hydrogen-substituted polyfluorooctane ether sulfonate (6:2 H-PFESA) as the sole metabolite. The results suggest that the mechanism for reductive dechlorination of 6:2 Cl-PFESA is likely co-metabolism rather than organohalide respiration. Additionally, the product 6:2 H-PFESA showed lower sorption affinity, indicating increased mobility in the environment.

Summary: Photoinitiators (PIs) are anthropogenic chemicals used in polymerization systems to initiate polymerization reactions. Their wide application in commercial products has led to environmental issues. This study reviews the occurrence, human exposure, and toxicity of PIs and suggests future research directions. PIs have been found in commercial products, water, sediment, sewage sludge, indoor dust, serum, and breast milk. Benzophenone is the most detected congener. PIs have toxic effects, such as carcinogenicity and endocrine disruption. Future research should focus on coexposure effects, metabolism/transformation pathways, and the development of greener PIs.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
