Researchers from the H2OforAll project have published a new scientific review offering a holistic perspective on disinfection by-products (DBPs), from their formation in drinking water to their analytical detection, regulation and future monitoring.
The publication, “Holistic overview on disinfection by-products formation and their analytical characterization,” brings together current scientific knowledge on a group of compounds that continue to attract growing attention in the fields of water treatment, environmental protection and public health.
DBPs are formed when disinfectants used during water treatment react with organic or inorganic substances present in source waters. Because these reactions can generate a wide range of chemical compounds, monitoring DBPs remains a significant technical challenge.
The review highlights several factors that complicate their assessment, including low concentrations, chemical instability and demanding sample preparation and analytical procedures. These challenges can make it difficult for existing monitoring approaches to fully respond to emerging regulatory and water quality needs.
The authors examine advances across several areas, including the characterisation of DBP precursor compounds, DBP formation mechanisms, analytical detection and quantification techniques, current regulatory frameworks and future scientific and technological challenges.
The publication also points to promising developments such as in-line monitoring through robust sensing platforms and innovative treatment and disinfection technologies that could support safer water management.
The study contributes to the wider research efforts of European projects working to better understand contaminants in drinking water and develop more effective approaches for monitoring, treatment and risk management.
