[Public Comments] New Jersey Department of Environmental Protection Comments on Draft World Health Organization Drinking Water Quality Guidelines for PFOA and PFOS
17 Nov 2022
NJDEP identified the need for many revisions in both the factual information and the conclusions about health effects, treatment removal, and other topics discussed in the draft WHO document.
Nontargeted screening reveals fluorotelomer ethoxylates in indoor dust and industrial wastewater.
15 Nov 2022 | Environ. Int.
FTEOs were detected in 60% of indoor dust samples and c. 40% of industrial effluent samples, with the highest concentrations in healthcare facility dust and the effluents from electroplating facilities, manufacturers of cosmetics and personal care products, and linen cleaning services for healthcare and work uniforms.
Associations of per- and polyfluoroalkyl substances (PFAS) and their mixture with oxidative stress biomarkers during pregnancy
14 Nov 2022 | Environ Intern
PFOS was associated with elevated oxidative stress levels during pregnancy, which may affect fetal development.
Paints: A Source of Volatile PFAS in Air - Potential Implications for Inhalation Exposure
11 Nov 2022 | Environ Sci Technol
Common paints were found to contain 6:2 FTOH and 6:2 diPAP that accounted for up to 17% of total fluorine, with 40% of FTOH mass lost upon drying. Exposure estimates suggest that PFAS exposure while painting could exceed recommended reference doses for children and adults.
Apparent Half-Lives of Chlorinated-Perfluorooctane Sulfonate and Perfluorooctane Sulfonate Isomers in Aviation Firefighters
11 Nov 2022 | Environ Sci Technol
The average half-life of Cl-PFOS among firefighters with previous exposure to fluorinated AFFF was 5.0 years, although other forms of PFOS had half-lives ranging from 4-11.5 years.
Per- and Poly-Fluoroalkyl Substances in Runoff and Leaching from AFFF-Contaminated Soils: a Rainfall Simulation Study
10 Nov 2022 | Environ Sci Technol
PFAS concentrations in AFFF-contaminated soils declined significantly after the first rainfall event, but desorption and transport in both runoff and leachates persisted over several rainfall events.
[Public Comments] International Society for Environmental Epidemiology Comments on Draft World Health Organization Drinking Water Quality Guidelines for PFOA and PFOS
10 Nov 2022 | ISEE Website
The ISEE, a leading scientific association in environmental epidemiology that impacts research, training, and policy worldwide, identified that the provisional WHO guidelines neither protect human health nor include the latest scientific literature.
Legacy and emerging airborne per- and polyfluoroalkyl substances (PFAS) collected on PM2.5 filters in close proximity to a fluoropolymer manufacturing facility
9 Nov 2022 | Environ Sci Process Impacts
Twelve emerging and ten legacy PFAS compounds were detected in aerosol samples around a fluoropolymer manufacturing facility at concentrations higher than at regional background sites, suggesting the manufacturing facility as the local source for these compounds.
Controlled uptake of PFOA in adult specimens of Paracentrotus lividus and evaluation of gene expression in their gonads and embryos
9 Nov 2022 | Environ Sci Pollut Res Int
PFOA is persistent and bioaccumulative in sea urchins and adversely affects their health by causing significant changes in the expression of some key target genes and the occurrence of developmental anomalies in the embryos.
Interface hydrogen bonding dominated perfluorooctanoic acid (PFOA) accumulation by iron particles in drinking water pipes
8 Nov 2022 | Chemosphere
Old unlined drinking water pipes had a higher accumulation capacity for PFOA than new pipes due to the accumulation of some iron particles.
Organic Fluorine as an Indicator of Per- and Polyfluoroalkyl Substances in Dust from Buildings with Healthier versus Conventional Materials
4 Nov 2022 | Environ Sci Technol
Classrooms renovated with “healthier” furniture and carpeting reported to be PFAS-free had on average 66% less PFAS and 49% less extractable organic fluorine levels in dust compared to conventional rooms, demonstrating that materials solutions reduce the accumulation of PFAS within buildings.
Treatment technologies for removal of per-and polyfluoroalkyl substances (PFAS) in biosolids
2 Nov 2022 | J. Chem. Eng.
Different PFAS destruction technologies such as incineration, hydrothermal liquefaction, pyrolysis, thermal hydrolysis, supercritical water oxidation, and several other processes, are discussed in this review.
Developing an Exposure Burden Score for Chemical Mixtures Using Item Response Theory, with Applications to PFAS Mixtures
2 Nov 2022 | Environ Health Perspect
A novel exposure burden score method for chemical mixtures was developed and applied to estimate the exposure burden of PFAS mixtures and resulted in stronger estimated associations with cardio-metabolic outcomes in the general U.S. population compared to summed PFAS concentrations.
The effects of perfluoroalkyl and polyfluoroalkyl substances on female fertility: A systematic review and meta-analysis
2 Nov 2022 | Environ Res
Increased levels of PFAS exposure are associated with reduced female fertility, which should be taken into account for risk assessments of manufacturing products containing PFAS.
Exposure to per- and polyfluoroalkyl substances and glycemic control in older US adults with type 2 diabetes mellitus
2 Nov 2022 | Environ Res
In older US adults with known type 2 diabetes, poor glycemic control is more likely to be observed in those with high serum levels of PFNA & PFHxS and PFDeA in men.
