The Priority compounds & Virus control theme focuses on the chemical-free degradation and inactivation of human-originated trace contaminants, transforming them into harmless products. We explore two key areas: First, we develop efficient, UV-based advanced oxidation processes (AOPs) to ensure safe drinking water from impaired sources. Second, we aim to create rapid, simple validation methods to measure log removal and inactivation values, crucial for maintaining high safety standards. Without sensitive operational monitoring, valuable log credits may be lost.
Additionally, we address the formation of transformation products (TPs) during AOPs. While AOPs effectively degrade micropollutants like pharmaceuticals and pesticides, some TPs may remain biologically active and go undetected by conventional methods. To tackle this, we combine high-resolution mass spectrometry (HRMS), effect-directed analysis (EDA), and machine learning to identify and assess TPs’ potential toxicity, enhancing both treatment safety and effectiveness. The theme started in 2009.
