Occurrence and risk assessments of per-and polyfluoroalkyl substances in tea bags from India
1 May 2023 | Food Control
PFOS, PFHxS, and PFuNA were abundantly present in tea bag materials and tea powder, with PFOS and PFHxS contributing to high levels of exposure.
Association of Early Pregnancy Perfluoroalkyl and Polyfluoroalkyl Substance Exposure With Birth Outcomes
1 May 2023 | JAMA Netw Open
Associations between blood PFOS and PFNA concentrations and lower birth weight, and between PFNA and preterm birth were noted only among mothers whose prenatal folic acid levels were low.
Evidence of compost contamination with per- and polyfluoroalkyl substances (PFAS) from "compostable" food serviceware
1 May 2023 | Biointerphases
Including compostable serviceware in compost likely contaminates the finished compost with PFAS – including PFOA – and threatens surrounding groundwater, surface waters, and crops.
Association between prenatal and early postnatal exposure to perfluoroalkyl substances (PFAS) and IQ score in 7-year-old children from the Odense Child Cohort
29 Apr 2023 | Am J Epidemiol.
Maternal PFOS and PFNA concentrations were associated with lower IQ in children.
Lithium-ion battery recycling: a source of per- and polyfluoroalkyl substances (PFAS) to the environment?
27 Apr 2023 | Environ. Sci: Process. Impacts.
This review highlights the need to further study emissions of fluorinated substances during lithium-ion battery recycling and suggests that substitution or treatment of PFAS-based materials is needed.
[Opinion] What Limits Will the World Health Organization Recommend for PFOA and PFOS in Drinking Water?
26 Apr 2023 | Environ. Sci. Technol.
To support the work of public health agencies worldwide providing people with safe drinking water, the WHO guidance levels need to be updated to reflect scientific evidence.
Analytical approaches for screening of per-and poly fluoroalkyl substances in food items: A review of recent advances and improvements
26 Apr 2023 | Environ Pollut
The authors suggest improvements for PFAS analysis in foods, such as using emerging extraction methods as a fast and less labor-intensive approach, and make further suggestions regarding PFAS detection.
Impact of PFAS exposure on prevalence of immune-mediated diseases in adults in the Czech Republic
26 Apr 2023 | Environ Res.
PFAS exposure was found to have some adverse immune effects, including an association of elevated PFOS levels in men with higher rates of eczema.
Smouldering to treat PFAS in sewage sludge
25 Apr 2023 | Waste Manage.
Smoldering combustion completely removed all 4-8 carbon chain length PFAS from sewage sludge under all conditions, though extremely high temperatures and the addition of CaO were needed to mineralize the PFAS completely.
Early life exposure to low-dose perfluorooctane sulfonate disturbs gut barrier homeostasis and increases the risk of intestinal inflammation in offspring
24 Apr 2023 | Environ Pollut
Low-dose PFOS exposure disrupted the developing digestive functions in a human model species.
Association of perfluoroalkyl and polyfluoroalkyl substances with sex hormones in children and adolescents 6-19 Years of age
23 Apr 2023 | Environ Pollut
Serum concentrations of individual PFAS and mixtures were associated with changes in developmental hormone levels.
Mechanistic Middle-Out Physiologically Based Toxicokinetic Modeling of Transporter-Dependent Disposition of Perfluorooctanoic Acid in Humans
18 Apr 2023 | ES&T
A new model was developed to explain the persistence of PFOA in humans after both high-dose, acute and low-dose, chronic exposures.
Global ocean contamination of per- and polyfluoroalkyl substances: A review of seabird exposure
18 Apr 2023 | Chemosphere
Seabirds had higher levels of PFOS exposure – often exceeding toxicity reference values in places like the Baltic Sea and the San Francisco Bay – in the late 1990s and early 2000s, consistent with the phase-out of PFOS-based chemicals.
70 analyte PFAS test method highlights need for expanded testing of PFAS in drinking water
17 Apr 2023 | Sci. Total Environ.
Unregulated Contaminant Monitoring Rule will likely underreport PFAS in drinking water due to existing methods’ limited coverage and higher minimum reporting limits. The most common PFAS present was PFPrA, a poorly studied and monitored short-chain PFAS.
Pharmaceuticals Account for a Significant Proportion of the Extractable Organic Fluorine in Municipal Wastewater Treatment Plant Sludge
17 Apr 2023 | Environ. Sci. Technol. Lett.
Pharmaceutical substances and pesticides can contribute to sizable portions of the organofluorine content detected in wastewater treatment plant sludge.
