The emission of per- and polyfluoroalkyl substances (PFAS) from functional textiles was investigated via an outdoor weathering experiment in Sydney, Australia. Polyamide (PA) textile fabrics treated with different water-repellent, side-chain fluorinated polymers (SFPs) were exposed on a rooftop to multiple natural stressors, including direct sunlight, precipitation, wind, heat for 6-months. After weathering, additional stress applied the through abrasion washing. Textile characterization...
The quantity and composition of fibers released from functional textiles during accelerated washing were investigated using the GyroWash method. Two fabrics [polyamide (PA) polyester/cotton (PES/CO)] selected coated with perfluorohexane-based side-chain fluorinated polymers. Fibers ranged ∼10 to 500 μ a similar distribution for two textile types. PA-based fabric considerably more >20 μm in length compared PES/CO-based (>1000/GyroWash PA vs ∼200/GyroWash PES/CO). After one (2-15 domestic...
A framework for characterizing per- and polyfluoroalkyl substances (PFASs) in life cycle impact assessment (LCIA) is proposed. Thousands of PFASs are used worldwide, with special properties imparted by the fluorinated alkyl chain. Our makes it possible to characterize a large part family introducing transformation fractions that translate emissions primary emitted into highly persistent terminal degradation products: perfluoroalkyl acids (PFAAs). Using PFAA-adapted characterization model,...
Given their extensive production volumes and potential to form persistent perfluoroalkyl acids (PFAAs), there is concern surrounding the ongoing use of side-chain fluorinated polymers (SFPs) in consumer products. Targeted SFP quantification relies on matrix-assisted laser desorption ionization time-of-flight mass spectrometry, which can suffer from poor accuracy high detection limits. Alternatively, total fluorine (TF)-based methods may be used, but these approaches report concentrations a...
Organophosphate flame retardants (OPFRs) are a group of semi-volatile organic compounds (SVOCs) and among the most abundant contaminants indoors. Their indoor presence has been associated with potential health risks however there is limited understanding as to how they released from sources. This study uses an emission micro-chamber explore one currently understudied chemical migration pathways; direct transfer between source material settled dust in contact source. A tris(2-chloroisopropyl)...
A significant number of consumer goods and building materials can act as emission sources flame retardants (FRs) in the indoor environment. We investigate relationship between source strength levels 19 brominated (BFRs) seven organophosphate (OPFRs) air dust collected 38 microenvironments Norway. use modeling methods to back-calculate rates from measurements identify possible indications an emission-to-dust pathway. Experimentally based estimates provide a satisfactory indication relative...
Chemical safety assessment requires the inclusion of information on potential transformation products. Such is often lacking for chemicals considered as alternatives making a comprehensive chemical substitution challenging. To address this challenge methodological framework investigating environmental alternative presented. The developed methodology involves combined use in silico tools, biodegradation testing and suspect screening analysis prediction identification pathways proposed was...
