- 'Ultrashort' PFAS compounds have been detected in people’s urine and serum, and in the dust in their homes. 'Ultrashort' PFAS are thought to be suitable replacements for “forever chemicals” PFOS/ PFOA. However, recent research have suggested that they could be more toxic than the longer compounds. https://www.acs.org/pressroom/presspacs/2023/october/ultrashort-pfas-compounds-detected-in-people-and-their-homes.html 83 comments science
