Sources of exposure to per- and polyfluorinated alkyl substances (PFAS) include food, water, given that humans spend typically 90% our time indoors, air dust. Quantifying PFAS prevalent such as neutral, volatile PFAS, estimating their risk is thus important. To accurately measure these compounds polyethylene (PE) sheets were employed validated passive detection tools, analyzed by gas chromatography-mass spectrometry. Air concentrations compared dust carpet reported elsewhere. Partitioning...
Per- and polyfluoroalkyl substances (PFAS) are a diverse class of fluorinated anthropogenic chemicals that include perfluoroalkyl acids (PFAA), which widely used in modern commerce. Many products environmental samples contain abundant precursors can degrade into terminal PFAA associated with adverse health effects. Fish consumption is an important dietary exposure source for PFAS bioaccumulate food webs. However, little known about bioaccumulation precursors. Here, we identify quantify...
Wastewater receives per- and polyfluoroalkyl substances (PFAS) from diverse consumer industrial sources, discharges are known to be a concern for drinking water quality. The PFAS family includes thousands of potential chemical structures containing organofluorine moieties. Exposures few well-studied PFAS, mainly perfluoroalkyl acids (PFAA), have been associated with increased risk many adverse health outcomes, prompting federal regulations six compounds in 2024. Here, we find that the...
A polyurethane foam passive air sampler shows large inter-compound variability in sampling performance for semivolatile organic compounds the outdoor environment.
Drinking water supplies across the United States have been contaminated by firefighting and fire-training activities that use aqueous film-forming foams (AFFF) containing per- polyfluoroalkyl substances (PFAS). Much of AFFF is manufactured using electrochemical fluorination 3M. Precursors with six perfluorinated carbons (C6) non-fluorinated amine substituents make up approximately one-third PFAS in 3M AFFF. C6 precursors can be transformed through nitrification (microbial oxidation) moieties...
This study investigates the distribution of polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD) and a group novel flame retardants (NFRs) on atmospheric aerosols. Two high volume cascade impactors were used to collect particulate fractions ambient air over one year period at urban rural sites. The majority FRs found finest aerosols (<0.95 μm). Concentrations HBCD higher than those ΣPBDEs. Moreover, we noted seasonality spatial differences in particle size distributions, yet...
Most monitoring programs next to large per- and polyfluoroalkyl substances (PFAS) sources focus on drinking water contamination near source zones. However, less is understood about how these affect downgradient hydrological systems food webs. Here, we report paired PFAS measurements in water, sediment, aquatic biota along a gradient away from zones contaminated by the use of legacy aqueous film-forming foam (AFFF) manufactured using electrochemical fluorination. Clustering analysis indicates...
PUF passive air samplers perform well for gas phase SVOCs while they are inconsistent particle associated in non-industrial indoor environments.
Semivolatile organic compounds (SVOCs) emitted from consumer products, building materials, and indoor outdoor activities can be highly persistent in environments. Human exposure to environmental contamination with polychlorinated biphenyls (PCBs) was previously reported a region near former PCB production facility Slovakia. However, we found that the residential levels did not correlate distance facility. Rather, this those literature were related historic use on national scale inferred...
A newly constructed university building was selected for targeted assessment of changes in the levels flame retardants and legacy contaminants during installation equipment, furniture, electronics, first year use. Indoor air samples were collected several periods intensive equipment to determine a relationship between introduced concentrations profiles indoor air. Samples analyzed polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDDs), new types retardants: brominated...
Bangladesh hosts extensive textile manufacturing, for some of which per- and polyfluorinated alkyl substances (PFAS) have been used to impart water dirt repellency, among other things. Textile waste emissions the atmosphere discharge into rivers bodies could present a significant concern human ecosystem health, but there is little information on PFAS in Bangladesh. To assess presence ionic their precursors air from Dhaka, Bangladesh, polyethylene sheets were deployed 28 days as passive...
Per- and polyfluorinated alkyl substances (PFAS) are a family of pollutants high concern due to their ubiquity negative human health impacts. The long-range marine transport PFAS was observed during year-long deployments passive tube samplers in the Fram Strait across three depth transects. Time weighted average concentrations ranged from 2.4 360 pg L–1, 10 different were regularly observed. profiles generally similar those previously characterized for polycyclic aromatic hydrocarbons (PAHs)...
Abstract Polycyclic aromatic hydrocarbons (PAHs) are continuously released from multiple sources and prone to long‐range transport. Little is known regarding their presence, transport fate in remote deep oceans. Polyethylene passive samplers were hence deployed at moorings surface seawater the Fram Strait Canadian Archipelago, as well air water of lower Great Lakes, a potential high‐emission region, understand PAHs Arctic. Dissolved showed significantly higher concentrations Lakes than those...
