Fluorotelomer alcohols (FTOHs) are a class of per- and polyfluoroalkyl substances (PFAS) that have been reported in both indoor and outdoor air and are found in an array of... -
Exposure to per- and polyfluoroalkyl substances (PFAS) in North Carolina...
Per and polyfluoroalkyl substances (PFAS) are ubiquitous in the indoor environment, resulting in indoor exposure. However, a dearth of concurrent indoor multi-compartment PFAS... -
The impact of particle size on PFAS concentrations in dust from homes in...
Per- and polyfluoroalkyl substances (PFAS) are manufactured chemicals and ubiquitously present in the environment, including in homes. The two major exposure pathways for PFAS... -
Analytical method interferences for perfluoropentanoic acid (PFPeA) and...
While high-resolution MS (HRMS) can be used for identification and quantification of novel per- and polyfluorinated alkyl substances (PFAS), low-resolution MS/MS is the more... -
Per- and polyfluoroalkyl substances (PFASs) in airborne particulate matter...
Per- and polyfluoroalkyl substances (PFASs), with their water- and heat-resistant properties, have been widely used in industrial and consumer products, including floor waxes.... -
Partitioning of Neutral PFAS in Homes and Release to the Outdoor...
The distribution and fate of per- and polyfluoroalkyl substances (PFAS) in homes are not well understood. To address this, we measured nine neutral PFAS in dust, airborne... -
Legacy and emerging airborne per- and polyfluoroalkyl substances (PFAS)...
Large fluoropolymer manufacturing facilities are major known sources of per- and polyfluoroalkyl substances (PFAS), many of which accumulate in groundwater, surface water,... -
Indoor air concentrations of PM2.5 quartz fiber filter-collected ionic PFAS...
Per- and polyfluoroalkyl substances (PFAS) are prevalent in consumer products used indoors. However, few measurements of ionic PFAS exist for indoor air. We analyzed samples... -

Per- and polyfluoroalkyl substances (PFAS), which include fluorotelomer alcohols (FTOHs), are synthetic chemicals used in consumer products because of their water-, stain-, and... -
External liquid calibration method for iodide chemical ionization mass...
Per- and polyfluoroalkyl substances (PFAS) are manufactured chemicals that have been detected across the globe. Fluorotelomer alcohols (FTOHs) are one PFAS class commonly found... -
Enhanced Ice Nucleation of Simulated Sea Salt Particles with the Addition of...
Ice-nucleating particles (INPs) impact global climate by altering cloud formation and properties. The ability of aerosol particles to nucleate ice is in part determined by... -
Cloth–Air Partitioning of Neutral Per- and Polyfluoroalkyl Substances (PFAS)...
Partitioning of per- and polyfluoroalkyl substances (PFAS) to indoor materials, including clothing, may prolong the residence time of PFAS indoors and contribute to exposure.... -
