Background and Relevance

The risks caused by micropollutants, even just negative perceptions about this issue are a major impediments to the acceptance and use of recycled water. Thousands of chemicals are present in recycled water and it is likely that the majority of transformation products (TPs) generated during water recycling processes have not even been identified, let alone characterized in terms of toxicity. Although individual chemicals are typically present at very low concentrations, they can act jointly resulting in additive or potentially even interactive (synergistic or antagonistic) mixture effects. In this project, we will perform mixture experiments with regulated chemicals and will assess the role of TPs in the toxicity of mixtures.
