The aim of this study was to assess the soil-water partitioning behavior a wider range per- and polyfluoroalkyl substances (PFASs) onto soils covering diverse soil properties. PFASs studied include perfluoroalkyl carboxylates (PFCAs), perfluoroalkane sulfonates (PFSAs), fluorotelomer (FTSs), nonionic sulfonamides (FASAs), cyclic PFAS (PFEtCHxS), ether acids (GenX, ADONA, 9Cl-PF3ONS), three aqueous film-forming foam (AFFF)-related zwitterionic (AmPr-FHxSA, TAmPr-FHxSA, 6:2 FTSA-PrB)....
In many low-income countries, the poor conditions of sanitation systems have been a significant cause mortality since they accelerate waterborne disease transmission. Developing in these countries is pressing concern both public and private sectors. This research investigated decentralized domestic wastewater treatment system using ultraviolet light-emitting diodes (UV-LEDs). Although UV-LED disinfection has become more widespread recent years, it novel approach for treatment. Domestic was...
Monitoring contamination from per- and polyfluoroalkyl substances (PFASs) in water systems impacted by aqueous film-forming foams (AFFFs) typically addresses a few known PFAS groups. Given the diversity of PFASs present AFFFs, current analytical approaches do not comprehensively address range these systems. A suspect-screening nontarget analysis (NTA) approach was developed applied to identify novel groundwater samples contaminated historic AFFF use. total 88 were identified both passive...
Landfills are the primary endpoint for disposal of PFAS-laden waste, which subsequently releases PFAS to surrounding environments through landfill leachate. Ozone foam fractionation emerges as a promising technology removal address issue. This study aims (i) assess effectiveness ozone system remove from leachate, and (ii) quantify equilibrium adsorption onto gas-water interface bubbles, followed by comparison with air fractionation. The results show that is effective more than 90% long-chain...
Soil contaminated with aqueous film-forming foams (AFFFs) containing per- and polyfluoroalkyl substances (PFASs) at firefighting training sites has become a major concern worldwide. To date, most studies have focused on assessing soil–water partitioning behavior of PFASs the key factors that can affect their sorption, whereas leaching from soils not yet been widely investigated. This study evaluated desorption wide range twelve using Australian Standard Leaching Procedure (ASLP), U.S. EPA...
This study investigated the mobilization of a wide range per- and polyfluoroalkyl substances (PFASs) present in aqueous film-forming foams (AFFFs) water-saturated soils through one-dimensional (1-D) column experiments with view to assessing feasibility their remediation by soil desorption washing. Results indicated that sorption/desorption most shorter-carbon-chain PFASs (C ≤ 6) reached greater than 99% rapidly─after approximately two pore volumes (PVs) were well predicted an equilibrium...
Per- and polyfluoroalkyl substances (PFAS) within concrete pads impacted by historical firefighting training using aqueous film-forming foam (AFFF) may be potential secondary sources of PFAS due to surficial leaching. This study aimed (i) characterize the effectiveness two commercially available sealants (Product A Product B) in mitigating leaching five (e.g., PFOS, PFOA, PFHxS, PFHxA, 6:2 FTS) from surfaces at laboratory-scale, (ii) develop a model forecast cumulative same over 20 years...
Firefighting training grounds (FTGs) may serve as a potential secondary source for the release of per- and polyfluoroalkyl substances (PFAS) due to historic use aqueous film-forming foams (AFFFs). Understanding heterogenicity vertical distribution PFAS in AFFF-impacted concrete is important risk management remediation. This study assessed whether desorption electrospray ionization mass spectrometry imaging (DESI MSI) can be used analyze core from an FTG provide PFAS. PFOS PFHxS were detected...
Decentralized wastewater treatment systems enable to be treated at the source for cleaner discharge into environment, protecting public health while allowing reuse agricultural and other purposes. This study, conducted in Thailand, investigated a decentralized system incorporating physical photochemical process. Domestic from university campus conventional septic tank effluent small community were filtered through woven-fiber microfiltration (WFMF) membrane as pretreatment ultraviolet (UV)...
