A wastewater balance reveals unexpectedly high TFA input from human water use

Abstract Trifluoroacetate (TFA) is a member of the PFAS group and shares their persistence. Its very small molecular size and anionic character makes it, in contrast to many other PFAS, highly water-soluble and mobile in the aquatic environment. Wastewater shows elevated TFA conc...

The WoKaS-Iso database: workflow for a global compilation of oxygen-18 and deuterium records in karst springs and cave drip water for enhanced understanding of karst systems

For analysing karst hydrogeological systems, observations of karst springs and cave drips are considered indispensable. In addition to hydrometric observations, knowing the oxygen and hydrogen stable isotope ratios has improved the understanding of vadose zone and aquifer dynamic...
