Improving the definition of water quality criteria: linking organism recovery times to mechanism of action and acute-to-chronic ratios

Improving the definition of water quality criteria: linking organism recovery times to mechanism of action and acute-to-chronic ratios

Start

  • 2008

The project systematically investigates a novel approach to aquatic ecotoxicology which is based on measuring and simulating toxic processes in time. It applies the mechanistic understanding of toxic effects on aquatic organisms to develop a process-based interpretation of acute-to-chronic (ACR) datasets. Furthermore this research will establish a better understanding of how organisms recover from exposure to different chemicals and how that recovery is related to mechanisms of action (MEoA) as well as how acute toxicity is related to chronic effects. Ultimately, this study will inform risk assessment and facilitate the definition of water quality criteria based on evidence about the time-course of toxic effects (ACR) and mechanistic information (MEoA).
