The One Health concept is by definition an interdisciplinary approach that holistically addresses the current and future challenges surrounding our aquatic environments. This research line integrates earth system science and aquatic biogeochemistry with environmental chemistry and engineering. This arguably rare combination, is powerful in better understanding the behavior of chemicals in our aquatic and urbanized environments. The processes within the Anthroposphere are complex and analytical chemistry is the node for this synthesis approach and to interconnect disciplines. For example, the linkages between precursors in extremely complex natural dissolved organic matter and their reaction with disinfectants, such as free chlorine, remain a human and environmental health challenge.

Furthermore, multiple analytical windows should be combined to paint a much clearer picture of the chemical world we are living in and to map the sources and fate of environmental stressors. A key aspect to tackle this wicked problem is in the devlopment of novel organic tracers that are indicative either for specific contaminations, processes, or even ecosystem functioning.
