Speciation‐Controlled C–F Bond Functionalization Enabled by Zwitterionic Pnictinidenes

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Zwitterionic pnictinidenes turn C–F activation into C–X bond construction, enabling broad defluorinative functionalization of polyfluoro(hetero)arenes under mild conditions. Rather than following a metallomimetic Sb(I)/Sb(III) redox turnover, catalysis is redirected by ligand scrambling into a redox‐neutral manifold, revealing catalyst speciation as a ...

Per- and polyfluoroalkyl substances and the gut microbiota in infants: A scoping review

Environmental Research
Per-and polyfluoroalkyl substances (PFASs) are persistent environmental chemicals associated with adverse health effects. Emerging evidence suggests PFAS exposure may influence gut microbiota composition, which is a critical determinant of health particularly during infancy.

Asymmetric Regulatory Embeddedness and Post‐Brexit Governance: Explaining Adaptive Convergence in the United Kingdom

JCMS: Journal of Common Market Studies, EarlyView.
Abstract Why has the United Kingdom repeatedly restored substantive compatibility with European Union (EU) regulatory norms despite formal withdrawal? This article introduces the concept of asymmetric regulatory embeddedness (ARE) to explain post‐membership governance in highly integrated sectors. ARE captures the structural condition in which a former

Assessment of per- and polyfluoroalkyl substances in Sydney drinking water

Chemosphere
Per- and polyfluoroalkyl substances (PFAS) have emerged as major persistent organic contaminants in global drinking water supplies. While PFAS contamination has been widely reported, their occurrence in Australian drinking water remains understudied. To address this gap, 32 tap water and 12 bottled water samples were collected across Sydney, Australia.

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, EarlyView.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Toward an urban soil health index: Emerging indicators for exposure, function, and resilience

Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Urban soils are among the most dynamic and human‐impacted soil systems, yet most soil health frameworks remain rooted in agricultural assumptions, capturing fertility and structure while missing urban‐specific concerns: contaminant exposure, extreme heterogeneity, thermal stress, and degraded ecosystem services.

Contaminations from Lithium-Ion Battery Fires—Per- and Polyfluoroalkyl Substances (PFAS) in Soot

Fluorinated substances are widely used in the different components of the lithium-ion battery cell, such as electrode binders, electrolyte, additives and separator materials. To date, most studies regarding the fluorinated contaminations from lithium-ion

Sustainability Assessment of Alternative Methods for Destruction of Per‐ and Polyfluoroalkyl Substances (PFAS) in Water

Remediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely recognized for their resistance to degradation and potential adverse health effects. The treatment of PFAS‐contaminated aqueous media (e.g., drinking water, wastewater, and leachate) has been extensively studied in the published literature; however, the

PFAS Vadose Zone Mass Discharge at an AFFF‐Impacted Site: 1. Validation Based on a Multiple Lines‐of‐Evidence Approach

Remediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Questions have recently been raised about the suitability of using porewater samples collected with suction lysimeters to estimate per‐ and polyfluoroalkyl substances (PFAS) mass discharge in the vadose zone. Multiple lines of evidence were evaluated to determine if porewater samples collected during a data gaps investigation in the former ...

The role of per‐ and polyfluoroalkyl substances in cognitive impairment and dementia

Alzheimer's & Dementia
AbstractPer‐ and polyfluoroalkyl substances (PFAS) are ubiquitous persistent organic pollutants. The neurotoxic and cardiometabolic effects of PFAS are well documented, leading to the hypothesis that exposure increases dementia risk. However, empirical data on PFAS in relation to cognitive impairment and dementia are weak, limited, and inconsistent ...
