Formatted Abstract/Summary
In vitro bioassays are frequently used for water quality assessment. The routine monitoring application is still hampered by the lack of appropriate interpretation guidelines. Here, we propose a systematic approach to derive effect-based water quality trigger values for three different types of toxic action: a) bioluminescence inhibition of Vibrio fischeri (Microtox), b) induction of an adaptive stress response pathway in the Nrf-2 mediated oxidative stress response (AREc32), c) inhibition of photosystem-II herbicides in the combined algae test. The trigger values can be derived by reading across from existing guideline values and accounting for mixture effects using the established mixture toxicity model of concentration addition. The derivation of the effect-based trigger values is illustrated on the example of recycled water and was applied to several different treatment schemes. All tested recycled water samples complied with the effect-based trigger values in all bioassays. This study was financially supported by the Australian Water Recycling Centre of Excellence.
