Ep 34 (PFAS in Sweden) Professor Ian Cousins - "Outside the safe operating space of a new planetary boundary for PFAS"
Welcome back to Talking PFAS Podcast I am a journalist and your host Kayleen Bell. And if you are joining us for the first time welcome.
My guest today is Professor Ian Cousins from the Department of Environmental Science at Stockholm University in Sweden. Now I have interviewed Ian before in Episode 21 when we spoke about his PFAS Essential Use paper and I highly recommend a listen to that one. Professor Cousins has a Bachelor of Science in Chemistry from the University of York and a PhD in environmental science from Lancaster University.
He is well-known for his research on the sources, transport and fate and exposure pathways of PFAS. In recent years Professor Cousins has written a series of policy related articles driven by his concern about the continued use of PFAS. Today we are going to be discussing his recent perspective paper “Outside the Safe Operating Space of a New Planetary Boundary for Per- and Polyfluoroalkyl Substances (PFAS” published in the Environmental Science & Technology journalist on the 2/8/2022.
Ian and colleagues state in their conclusion: “We conclude that PFAS define a new planetary boundary that has been exceeded based on PFAS levels in environmental media being ubiquitously above guideline levels. Irrespective of whether or not one agrees with our conclusion that the planetary boundary for PFAS is exceeded. It is nevertheless highly problematic that everywhere on earth where humans reside, recently proposed health advisories can not be achieved without large investment in advanced clean up technology.”
I will be heading to Adelaide in a couple of days (actually here now) for the International Clean Up Conference Adelaide 2022 where I hope to talk to a range of experts in Australia and around the world about some of those advanced clean up technologies that might exist now or be emerging so stay tuned for that one.
The US EPA has made some significant announcements regarding PFAS in the last couple of months and in today’s episode I will provide details of these.
