Introduction and Status of PFAS, a Diverse Family of >12,000 Forever Chemicals

Nadine Ding, Ph.D.

Volwiler Fellow

Abbott Laboratories

Thursday, October 26,  Webinar at 6:30 PM Pacific time


PFAS news has bombarded the airway, news media, and social media recently. One may ask exactly what PFAS chemicals are and why they are forever chemicals. This webinar will discuss the diverse nature of PFAS. Using PTFE synthesis as an example, I will discuss the source of PFAS contamination on the environment and humans. While low molecular weight PFAS surfactants are toxic, high molecular weight polymeric PFAS are “polymers with low concern” by European policy guideline, and they play a critical role in many 21st century technologies and in our daily life. I will briefly discuss the multitude of PFAS applications in a wide variety of technologies, and then provide a detailed focus through the example of one medical device in order to illustrate the benefit/risk profile of using fluoropolymers. In the presentation, I will also discuss the proposed regulations across different geographies and their potential impact on industrial use and on society.
