Selective oxidation of micropollutants during the phototransformation of bromate and chloride in ice: The role of BrCl and Br2

Key Points

• Selective oxidation of micropollutants occurs during the phototransformation process.
• Key evidence shows that BrCl and Br2 contribute significantly to this oxidation.
• Assessment using ice samples demonstrates the interaction between bromate and chloride.
• Highlights the importance of understanding these reactions in environmental conditions.
