“…Surfaces are more prevalent in indoor spaces compared to outdoor environments, with a typical surface area to volume ratio of 3 m –1 , comprising a larger fraction of the overall space. Surfaces influence a range of physical and chemical processes, acting as a sink for deposited aerosols, − partitioning of gaseous compounds, ,− and the formation of new species through surface-mediated reactions or heterogeneous reactions with trace indoor gases. ,− The composition and morphology of surfaces are highly diverse, and their evolution depends largely on location and the emission sources nearby. Modeling and field measurements have shown that thin films and particulate matter cover the surface over time. ,,, In the absence of external perturbations, these films and deposited aerosols can remain on surfaces for long periods of time.…”

“…The broad temporal and spatial scale surface processes occur over make it difficult to accurately capture these processes in authentic indoor environments. On an impermeable glass surface, experimental measurements and numerical models have demonstrated lower volatility organic compounds accumulate on the surface. ,,,,, Direct analyses of surface aging can be aided by high spatial and lateral resolution analyses, as initial particle depositions can be sparse and long-term film growth is predicted to be on the order of tens of nanometers. Higher-volatility compounds can reversibly adsorb onto surfaces or absorb into films, but capturing these transfer processes often involves model system studies in laboratory settings , or measuring loss behavior from the airborne fractions .…”

Water uptake by thin organic films and organic particles on glass substrates at 80% relative humidity was investigated using atomic force microscopy-infrared (AFM-IR) spectroscopy. Glass surfaces exposed to kitchen cooking activities show a wide variability of coverages from organic particles and organic thin films. Water uptake, as measured by changes in the volume of the films and particles, was also quite variable. A comparison of glass surfaces exposed to kitchen activities to model systems shows that they can be largely represented by oxidized oleic acid and carboxylate groups on long and medium hydrocarbon chains (i.e., fatty acids). Overall, we demonstrate that organic particles and thin films that cover glass surfaces can take up water under indoor-relevant conditions but that the water content is not uniform. The spatial heterogeneity of the changes in these aged glass surfaces under dry (5%) and wet (80%) conditions is quite marked, highlighting the need for studies at the nano-and microscale.

Studies suggest that exposure to potential endocrine disrupting chemicals (pEDCs) may contribute to adverse health outcomes, but pEDC exposures among firefighters have not been fully characterized. Previously, we demonstrated the military-style silicone dog tag as a personal passive sampling device for assessing polycyclic aromatic hydrocarbon exposures among structural firefighters. This follow-up analysis examined the pEDC exposures based on department call volume, duty shift, and questionnaire variables. Structural firefighters (n = 56) were from one high and one low fire call volume department (Kansas City, MO metropolitan area) and wore separate dog tags while on- and off-duty (n dogtags = 110). The targeted 1530 analyte semi-quantitative screening method was conducted using gas chromatography mass spectrometry (n pEDCs = 433). A total of 47 pEDCs were detected, and several less-frequently-detected pEDCs ( < 75%) were more commonly detected in off-compared to on-duty dog tags (conditional logistic regression). Of the 11 phthalates and fragrances detected most frequently ( > 75%), off-duty pEDC concentrations were strongly correlated (r = 0.31–0.82, p < 0.05), suggesting co-applications of phthalates and fragrances in consumer products. Questionnaire variables of “regular use of conventional cleaning products” and “fireplace in the home” were associated with select elevated pEDC concentrations by duty shift (paired t -test). This suggested researchers should include detailed questions about consumer product use and home environment when examining personal pEDC exposures.

“…Because HHCB has a shorter lifetime than AHTN in the atmosphere, − the HHCB/AHTN ratio was supposed to decline during long-range atmospheric transport. Namco Lake in the Tibetan Plateau, the highest altitude lake in the world, is located at an altitude of 4,718 m with no population centers nearby and mainly receives rainfall runoff and glacial meltwater.…”

Commercial chemicals, such as synthetic musks, are of global concern, but data on their occurrence and spatial distribution in aquatic environments of large scale are scarce. Two sampling campaigns were conducted in the present study to measure freely dissolved synthetic musks in freshwaters across China using passive samplers, along with biological coexposure at selected sites. Polycyclic musks (PCMs) dominated synthetic musks, with a detection frequency of 95%. Higher concentrations of PCMs were observed in densely populated Mid, East, and South China compared to less populated regions, indicating the significance of anthropogenic activities for synthetic musks in water. The concentration ratios of galaxolide (HHCB)/tonalide (AHTN) were significantly higher in low-latitude areas than in high-latitude areas from June to September, suggesting that solar radiation played an important role in the degradation of HHCB/AHTN. Significant correlations were found between dissolved concentrations of HHCB and AHTN and their lipid-normalized concentrations in coexposed fish and clam. The estimated hazard quotients for HHCB and AHTN in freshwater fish consumed by humans were less than 0.01 at all sampling sites except the Yangtze River Basin. These results help to understand the environmental fate and ecological risks of synthetic musks on a large geographical scale.
