In Situ Colloidal Activated Carbon for PFAS Remediation in Groundwater: Principles, Performance Expectations, and Lessons from the First Decade

Groundwater Monitoring &Remediation, EarlyView.
Abstract Injectable colloidal activated carbon (CAC) has been commercially used to remediate per and polyfluoroalkyl substances (PFAS) in groundwater since 2016. The basis of the technology is enhanced PFAS retention within the aquifer from engineered increases in aquifer‐matrix sorptivity (“PFAS enhanced retention”), with re‐equilibration from the ...

PFAS in the middle reaches of the Yangtze River, China: Tracking emerging alternatives and identifying priority control candidates based on their potential health implications

Ecotoxicology and Environmental Safety
Per- and polyfluoroalkyl substances (PFAS) are persistent environmental pollutants of global concern, yet systematic investigations into their occurrence and associated health risks in surface waters, particularly source waters, remain scarce. This study

Individual and mixtures of PFAS during pregnancy are associated with maternal cardiometabolic outcomes during pregnancy

Environmental Health
Introduction Per- and polyfluoroalkyl substances (PFAS) are endocrine-disrupting chemicals and widespread environmental contaminants. PFAS cross the placental barrier and reach the developing fetus with potential impacts on many organ systems.

PFAS Forensics, Part 1: Identifying Source‐Specific Signatures

Groundwater Monitoring &Remediation, EarlyView.
Abstract Environmental forensics employs a variety of analytical tools and techniques to evaluate contamination sources and assess the scope and impact of contamination in environmentally relevant media. The key questions for an environmental forensics analysis are where, when and how contamination occurred.

Environmental occurance, human exposure, and metabolism of per- and polyfluoroalkyl substances—a review

Environmental Research Communications
Per- and polyfluoroalkyl substances (PFASs) are known as ‘forever chemical’, commonly used in commercial and daily-life products. Due to their special physico-chemical characteristics, PFASs have been found in various environmental matrices, and can be ...

Associations of per- and polyfluoroalkyl substances (PFAS) and their mixture with risk of rheumatoid arthritis in the U.S. adult population

Environmental Health
Background Per- and polyfluoroalkyl substances (PFAS) are known environmental contaminants with immunosuppressive properties. Their connection to rheumatoid arthritis (RA), a condition influenced by the immune system, is not well studied.

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

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.
