This study identifies previously undetected PFAS in East Asian-Australian wildlife, emphasizing the TOP assay's role in ...

The Total Oxidizable Precursor assay has identified higher levels of PFAS in birds than previously recorded. A research team from the Norwegian University of Science and Technology (Trondheim, Norway) ...

As the cosmetics industry faces increasing scrutiny, one of the growing challenges is the management of Per- and Polyfluoroalkyl Substances (PFAS), also known as "forever chemicals." ...

They used a new method to analyze the samples, called the Total Oxidizable Precursor (TOP) assay, developed by co-author Lara Cioni. This method makes it easier to detect certain types of PFAS.

Per- and polyfluoroalkyl substances (PFAS) are a class of more than 15,000 human-made substances that have the same portion of chemical structure ...

we could stop emitting acid precursors and then acid rain would stop falling. But we can’t stop the microplastic cycle anymore. It’s there and it’s not going away.” The story of PFAS is ...
