During this webinar Dr. Cousins discussed the “essential use” concept, which was developed to determine when uses of hazardous chemicals have an essential function in modern society, and when they do not, as means of speeding up their phase out from society. In this presentation, he described the concept of “essential use” which was based on an existing approach described in the Montreal Protocol on Substances that Deplete the Ozone Layer. He then showed how the concept can be applied to the many uses of per- and polyfluoroalkyl substances, also known as PFAS.
Ian Cousins, PhD, has worked at the Department of Environmental Science at Stockholm University since 2002. His research comprises a combination of experimental and modelling approaches to investigate the sources, transport, fate and exposure of contaminants. For the last 20 years, he has conducted research on per- and polyfluoroalkyl substances (PFAS) and works closely with analytical chemists in his department to better understand the environmental behaviour of these contaminants. Prof. Cousins has published more than 170 peer-reviewed articles and 8 book chapters. He was designated as a Highly Cited Researcher in 2018 and 2020. In 2020, Prof. Cousins kicked off the PERFORCE3 project, which is a Europe-wide multi-partner doctoral research training programme in the field of PFAS that he coordinates. He recently became an Associate Editor of Environmental Science and Technology. Prof. Cousins’ website: https://www.aces.su.se/staff/
