Naidenko, Olga V.;Andrews, David Q.;Temkin, Alexis M.;Stoiber, Tasha;Uche, Uloma Igara;Evans, Sydney;Perrone-Gray, Sean research published 《 Investigating molecular mechanisms of immunotoxicity and the utility of ToxCast for immunotoxicity screening of chemicals added to food》, the research content is summarized as follows. The development of high-throughput screening methodologies may decrease the need for laboratory animals for toxicity testing. Here, we investigate the potential of assessing immunotoxicity with high-throughput screening data from the U.S. Environmental Protection Agency ToxCast program. As case studies, we analyzed the most common chems. added to food as well as per- and polyfluoroalkyl substances (PFAS) shown to migrate to food from packaging materials or processing equipment. The antioxidant preservative tert-butylhydroquinone (TBHQ) showed activity both in ToxCast assays and in classical immunol. assays, suggesting that it may affect the immune response in people. From the PFAS group, we identified eight substances that can migrate from food contact materials and have ToxCast data. In epidemiol. and toxicol. studies, PFAS suppress the immune system and decrease the response to vaccination. However, most PFAS show weak or no activity in immune-related ToxCast assays. This lack of concordance between toxicol. and high-throughput data for common PFAS indicates the current limitations of in vitro screening for analyzing immunotoxicity. High-throughput in vitro assays show promise for providing mechanistic data relevant for immune risk assessment. In contrast, the lack of immune-specific activity in the existing high-throughput assays cannot validate the safety of a chem. for the immune system.

We collected over 40 groundwater samples from a per- and polyfluoroalkyl substances (PFAS) impacted legacy fire fighting training area in Canada to develop an in-depth assessment of the relationship between PFAS and in situ microbial communities. Results suggest differential transport of PFAS of differing chain-length and head group. There is also evidence of PFAS degradation, in particular 6:2 FTS degradation Although PFAS constituents were not major drivers of microbial community structure, the relative abundance of over one hundred individual genera were significantly associated with PFAS chem. For example, lineages within the Oxalobacteraceae family had strong neg. correlations with PFAS, while the Desulfococcus genus has strong pos. correlations. Results also suggest a range of genera may have been stimulated at low to mid-range concentrations (e.g., Gordonia and Acidimicrobium), with some genera potentially inhibited at high PFAS concentrations Any correlations identified need to be further investigated to determine the underlying reasons for observed associations as this is an open field site with the potential for many confounding factors. Pos. correlations may ultimately provide important insights related to development of biodegradation technologies for PFAS impacted sites, while neg. correlations further improve our understanding of the potential neg. effects of PFAS on ecosystem health.

Morales-McDevitt, Maya E.;Becanova, Jitka;Blum, Arlene;Bruton, Thomas A.;Vojta, Simon;Woodward, Melissa;Lohmann, Rainer research published 《 The Air That We Breathe: Neutral and Volatile PFAS in Indoor Air》, the research content is summarized as follows. Sources of exposure to per- and polyfluorinated alkyl substances (PFAS) include food, water, and, given that humans spend typically 90% of their time indoors, air and dust. Quantifying PFAS that are prevalent indoors, such as neutral, volatile PFAS, and estimating their exposure risk to humans are thus important. To accurately measure these compounds indoors, polyethylene (PE) sheets were employed and validated as passive detection tools and analyzed by gas chromatog.-mass spectrometry. Air concentrations were compared to dust and carpet concentrations reported elsewhere. Partitioning between PE sheets of different thicknesses suggested that interactions of the PEs with the compounds are occurring by absorption. Volatile PFAS, specifically fluorotelomer alcs. (FTOHs), were ubiquitous in indoor environments. For example, in carpeted Californian kindergarten classrooms, 6:2 FTOH dominated with concentrations ranging from 9 to 600 ng m^-3, followed by 8:2 FTOH. Concentrations of volatile PFAS from air, carpet, and dust were closely related to each other, indicating that carpets and dust are major sources of FTOHs in air. Nonetheless, air posed the largest exposure risk of FTOHs and biotransformed perfluorinated alkyl acids (PFAA) in young children. This research highlights inhalation of indoor air as an important exposure pathway and the need for further reduction of precursors to PFAA.

J.;Kissel, John C.;Carignan, Courtney C.;Field, Jennifer A. research published 《 Disposition of Fluorine on New Firefighter Turnout Gear》, the research content is summarized as follows. Firefighter turnout gear is essential for reducing occupational exposure to hazardous chems. during training and fire events. Per-and polyfluoroalkyl substances (PFASs) are observed in firefighter serum, and possible occupational sources include the air and dust of fires, aqueous film-forming foam, and turnout gear. Limited data exist for nonvolatile and volatile PFASs on firefighter turnout gear and the disposition of fluorine on the individual layers of turnout gear. Further implications for exposure to fluorine on turnout gear are not well understood. Three unused turnout garments purchased in 2019 and one purchased in 2008, were analyzed for 50 nonvolatile and 15 volatile PFASs by liquid chromatog. quadrupole time-of-flight mass spectrometry (LC-qTOF-MS) and gas chromatog.-mass spectrometry (GC-MS), resp. Particle-induced gamma ray emission (PIGE), a surface technique, and instrumental neutron activation anal. (INAA), a bulk technique, were used to measure total fluorine. Bulk characterization of the layers by pyrolysis-GC/MS (py-GC/MS) was used to differentiate fluoropolymer (e.g., PTFE) films from textile layers finished with side-chain polymers. The outer layer, moisture barrier, and thermal layers of the turnout gear all yielded measured concentrations of volatile PFASs that exceeded nonvolatile PFAS concentrations, but the summed molar concentrations made up only a small fraction of total fluorine (0.0016-6.7%). Moisture barrier layers comprised a PTFE film, as determined by py-GC-MS, and gave the highest individual nonvolatile (0.159 mg F/kg) and volatile PFAS (20.7 mg F/kg) as well as total fluorine (122,000 mg F/kg) concentrations Outer and thermal layers comprised aromatic polyamide-based fibers (aramid) treated with side-chain fluoropolymers and had lower levels of individual nonvolatile and volatile PFASs. Equal concentrations of total fluorine by both PIGE and INAA on the outer and thermal layers is consistent with treatment with a side-chain fluoropolymer coating. New turnout gear should be examined as a potential source of firefighter occupational exposure to nonvolatile and volatile PFASs in future assessments.

Muensterman, Derek J.;Cahuas, Liliana;Titaley, Ivan A.;Schmokel, Christopher;De la Cruz, Florentino B.;Barlaz, Morton A.;Carignan, Courtney C.;Peaslee, Graham F.;Field, Jennifer A. research published 《 Per- and Polyfluoroalkyl Substances (PFAS) in Facemasks: Potential Source of Human Exposure to PFAS with Implications for Disposal to Landfills》, the research content is summarized as follows. Facemasks are important tools for fighting against disease spread, including Covid-19 and its variants, and some may be treated with per- and polyfluoroalkyl substances (PFAS). Nine facemasks over a range of prices were analyzed for total fluorine and PFAS. The PFAS compositions of the masks were then used to estimate exposure and the mass of PFAS discharged to landfill leachate. Fluorine from PFAS accounted only for a small fraction of total fluorine. Homologous series of linear perfluoroalkyl carboxylates and the 6:2 fluorotelomer alc. indicated a fluorotelomer origin. Inhalation was estimated to be the dominant exposure route (40%-50%), followed by incidental ingestion (15%-40%) and dermal (11%-20%). Exposure and risk estimates were higher for children than adults, and high phys. activity substantially increased inhalation exposure. These preliminary findings indicate that wearing masks treated with high levels of PFAS for extended periods of time can be a notable source of exposure and have the potential to pose a health risk. Despite modeled annual disposal of ~29-91 billion masks, and an assuming 100% leaching of individual PFAS into landfill leachate, mask disposal would contribute only an addnl. 6% of annual PFAS mass loads and less than 11 kg of PFAS discharged to U.S. wastewater.

Lv, Lina;Liu, Hua;Zhang, Wen;Chen, Junying;Liu, Zuozhen research published 《 Facile UV-curable fabrication of robust, anti-icing superhydrophobic coatings based on polyurethane》, the research content is summarized as follows. A novel robust, anti-icing, self-cleaning superhydrophobic coating was prepared via a simple, environmentally, friendly and efficient strategy which bond nanoparticles SiO₂ to the polyurethane surface under UV-curing. By controlling the content of nano-silica, a superhydrophobic coating with sliding angle (SA) of 2 ° and water contact angle (WCA) of 165 ° was constructed. The coating can be widely applied to various substrates with excellent anti-fouling properties and acid/alkali resistance. Meanwhile, the surface of coating is robust, can maintain superhydrophobic after 750 cycles of friction. In addition, the coating has a good anti-icing property which maintains excellent superhydrophobic after being placed at -10 °C for 100 h. Hence, the coating could be widely used on the surface of transmission lines and wind turbines.

Ma, Chunmeng;Peng, Hui;Chen, Hongrui;Shang, Wei;Zheng, Xingcan;Yang, Min;Zhang, Yu research published 《 Long-term trends of fluorotelomer alcohols in a wastewater treatment plant impacted by textile manufacturing industry》, the research content is summarized as follows. Fluorotelomer alcs. (FTOHs) are important precursors and substitutes of perfluoroalkyl carboxylic acids (PFCAs). This study investigated the long-term trends of FTOHs in a municipal wastewater treatment plant impacted by textile manufacturing industry (T-WWTP) in Wuxi city from 2013 to 2021. For comparison, four domestic wastewater treatment plants (D-WWTPs) were also selected for the investigation. The total concentrations of FTOHs, which were 9.8-43 ng/L, 5.9-29 ng/L and 10-50 ng/g in influent, secondary effluent, and sludge samples from the T-WWTP, were significantly higher than those of the D-WWTPs (p < 0.01). The significant correlation between decrease of mass loads for FTOHs and the increase for PFCAs was observed, suggesting the potential biotransformation of FTOHs to PFCAs. Concentration variation in FTOH concentrations was observed for the T-WWTP, which was in accord with the variation in annual output of textile products in Wuxi city (p = 0.005). The predominance of 8:2 FTOH in the influents of T-WWTP between 2013 and 2016 switched over to 6:2 FTOH in 2020-2021. This work highlighted the textile manufacturing industry as a significant discharge route for FTOHs to municipal WWTP, as well as the dramatic change in the usage of FTOHs in the textile manufacturing industry in Wuxi.

Maizel, Andrew C.;Shea, Stefanie;Nickerson, Anastasia;Schaefer, Charles;Higgins, Christopher P. research published 《 Release of Per- and Polyfluoroalkyl Substances from Aqueous Film-Forming Foam Impacted Soils》, the research content is summarized as follows. Per- and polyfluoroalkyl substances (PFASs) are highly mobile in the saturated subsurface, yet aqueous film-forming foam (AFFF)-impacted source zones appear to be long lasting PFAS reservoirs. This study examined the release of over one hundred anionic and zwitterionic PFASs from two AFFF-impacted surface soils under saturated conditions with packed soil columns. Perfluoroalkyl acids (PFAAs) were released more rapidly than their polyfluorinated precursors, while anionic PFASs that were present in partially uncharged states were released more slowly than PFASs that were present entirely as anions, as were zwitterionic PFASs with terminal cationic functional groups when compared with analogous zwitterions with only anionic terminal groups. Nonideal transport was observed in both per- and polyfluorinated classes, as soil column effluent concentrations of slowly released PFASs increased by up to 107-fold with sustained artificial groundwater flow. A flow-interruption experiment suggested the influence of rate-limited desorption on diverse PFAS classes, including PFAAs with as few as four perfluorinated carbons. These results suggest that during infiltration the slow, rate-limited desorption of anionic and zwitterionic PFAA precursors may result in these compounds comprising an increasingly large fraction of the remaining PFASs in AFFF-impacted surface soils.

Marsh, Zachary M.;Blom, Douglas A.;Stefik, Morgan research published 《 Tunable Fluorophobic Effect Determines Nanoparticle Dispersion in Homopolymers and Block Polymers》, the research content is summarized as follows. The controlled placement of nanoparticles (NPs) within homopolymers and block polymers is of broad interest for functional nanomaterials. This manuscript focuses on small mol.-stabilized NPs that bring a large fraction of functionality. For such NP mixtures with block polymers, the overwhelming focus to date has been the use of attractive interactions to localize hydrophilic NPs within the hydrophilic portion of block polymers. Related lipophilic approaches often place NPs at the block polymer interface. Here, a new modality for block polymer-NP control is developed that rather relies upon repulsion via the fluorophobic effect. Fluorinated species strongly associate via repulsion from nonfluorinated media. Here, fluorinated NPs are made with ligand mixtures for granular control over the strength of the fluorophobic effect. Small-angle X-ray scattering data reveal that all F-NPs readily phase sep. from polystyrene whereas increasing fluorophobic strength enables dispersions within a fluorinated homopolymer. Next, the F-NP placement within diblock polymers is investigated as a function of the fluorophobic strength. Weakly fluorophobic F-NPs are found predominantly near the diblock interface whereas strongly fluorophobic F-NPs are found to disperse throughout the fluorinated block. The controlled placement of NPs is an emerging way to self-assemble materials.

Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 647-42-7, formula is C8H5F13O, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , HPLC of Formula: 647-42-7

Matsumoto, Takuya;Kannan, Eichi;Tomioka, Misato;Nishino, Takashi research published 《 Effects of the high side-chain densities of hydrophobic poly(substituted methylene)s on their surface free energies》, the research content is summarized as follows. All the carbon atoms in the main chains of poly(substituted methylene)s possess side chains. The densities and chem. structures of the side chains drastically change the polymers′ thermal, mech., and surface properties. Herein, we focused on the surface properties and structures of poly(substituted methylene)s with hydrophobic side chains of Et and perfluoroalkyl groups and evaluated the effects of their side-chain densities. The surface free energy of poly(substituted methylene) with Et groups, C1-PEA, was lower than that of poly(Et acrylate) because the high d. of the side chains in C1-PEA decreased its chain mobility, and the dispersion component of its surface free energy was also suppressed. The surface free energy of poly(substituted methylene) with perfluoroalkyl groups containing only six carbon atoms in each fluoroalkyl group, C1-PF, was less than 10 mJ/m². In addition, the surface segregation of the perfluoroalkyl groups in the block-like copolymer and the greater hydrophobic properties of this polymer were observed compared to the corresponding random copolymer. The C1-PEA polymers showed dependence of their surface free energies and structures on their resp. preparation methods. Highly dense side chains facilitated the restriction of mol. chains and greater hydrophobic surface properties.

1H,1H, 2H, 2H-Tridecafluoro-1-n-octanol is a material used to improve nanotube composites. It is also used in the synthesis of a recyclable fluorous hydrazine carbothioate compound with NCS to catalyze the acetalization of aldehydes.

1H,1H,2H,2H-Tridecafluoro-1-n-octanol is a potent and selective halogenated hydrocarbon. It binds to DNA at the dinucleotide phosphate site, which is an important site for polymerase chain reaction (PCR) activation. 1HFN has been shown to be more effective than other halogenated hydrocarbons in vitro assays on rat liver microsomes. It has been used as an additive in wastewater treatment to remove organic contaminants and metal ions. In vivo studies have been carried out in CD-1 mice to determine the effects of 1HFN on the liver and kidneys; these studies showed no toxicological effects on these organs. 1HFN also has been shown to inhibit enzymes such as cytochrome P450 and monoamine oxidase B that are involved in drug metabolism and may lead to adverse reactions with drugs metabolized by these enzymes., 647-42-7.
