Achieving compliance with recent per- and polyfluoroalkyl substances (PFAS) regulations in the United States and Europe will require substantial effort and funding by municipal water providers, as well as chemical and product innovation to avoid regretta
Chemical Identity (CAS # or TSCA Accession Number / LVE number) The representative molecular structure of each PFAS. (If the specific chemical identity of the PFAS is unknown or not attainable, submitter can provide a generic name or description of the PFAS.) The physical form(s) of the PFA...
Per- and polyfluoroalkyl substances (PFAS) are emerging water contaminants with significant environmental and health impacts, posing challenges in water treatment due to their high stability and persistence. With increasing regulations, a critical need r
TSCA Section 8(a)(7) is one of the most significant regulations targeting PFAS and imposes new reporting requirements for a broad range of organizations. This guide will help you determine if you must report and how you can approach that task. Table of Contents What Is TSCA Section 8(a)(...
Levels are provided below in parts per million (ppm), parts per billion (ppb), or parts per trillion (ppt), depending on the matrix typically involved. WHAT'S NEW IN THIS EDITION? The state of Maine is currently undertaking several legislative and executive initiatives to monitor and manage ...
Thus, it remains unclear what the natural excretion rate of PFAS is during pregnancy, and more investigations are needed in order to determine this. It is well-known that PFAS pass the placenta, and it seems logical that the PFAS concentration during pregnancy decrease, partly explained by the...
and necessary actions for sustainable PFAS water treatment. The two major specific objectives are (1) to understand how and to what extent previous literature has evaluated sustainability of PFAS treatment technologies and (2) to develop a potential conceptual framework for characterizing the sustainabili...
PFAS are produced through two primary processes: direct fluorination (such as electrochemical fluorination) and oligomerization (like fluorotelomerization). Annually, over a megaton of PFAS is generated, with thousands of these compounds ending up in various consumer products [2]. The manufacturing, ...
PFAS is their persistence and bioaccumulative nature. These chemicals do not readily degrade in the environment, leading to their long-lasting presence, and they can accumulate in the food chain. The persistence of PFAS means that they do not break down easily over time, even in the face of ...
In the context of cancer, alterations in mitochondrial death pathways are known to underlie chemoresistance [29]. It is also known that compared to healthy cells, cancer cells have an increased number of mutations in mitochondrial deoxyribose nucleic acid (mtDNA), leading to mitochondrial dysfunction...
