Welcome to another episode of "The Exposure Scientist," where we dive into the complexities of environmental contaminants and their impact on public health. I'm your host, Dr. Alex LeBeau, and today we’re shedding light on the pervasive issue of PFAS, or per- and polyfluorinated alkyl substances, often dubbed "forever chemicals."
Our guest is Dr. Ioana Petrisor, a seasoned biochemist and chief chemist at Ensafe, who has dedicated her career to the environmental forensic study of emerging contaminants, including PFAS. In this episode, Dr. Petrisor unpacks the history, uses, and environmental persistence of PFAS—chemicals found in everything from firefighting foam to computer chips and consumer products.
We'll explore the challenges and advancements in detecting and analyzing these stubborn compounds, touching on sophisticated techniques like chemical fingerprinting, isotopic testing, and total oxidizable precursors. Dr. Petrisor also shares invaluable insights into how PFAS contamination can be tracked and managed at specific sites, revealing the intricate balance between scientific precision and practical application.
From the polar regions to our very own drinking water, PFAS contamination is a growing concern, and today's discussion will equip you with a deeper understanding of these indomitable chemicals. Stay tuned as we delve into the environmental fingerprinting of PFAS and uncover how regulators and scientists are addressing this silent but persistent pollutant.
