Our collaborator Dr. Peta Neale and her work in the EU project SOLUTIONS was featured in the Daily Newspaper “The Australian” https://www.theaustralian.com.au/higher-education.
Dr. Neale continues to collaborate with our department through her consultant company PNEC: Peta Neale Environmental Consulting.
A key paper for the understanding of the fate of chemicals in cell-based bioassays and their uptake into cells has just been published in "Chemical Research in Toxicology". Fabian Fischer showed, that uptake of neutral and ionised organics is sufficiently fast that bioassays with 24h exposure can be considered to have continuous constant exposure unless metabolism leads to depletion.

We lead a team of researchers from the EU project SOLUTIONS and the NORMAN network who developed a method to derive effect-based trigger values by read across from existing environmental quality standards of the Water Framework Directive of the EU. These triggers will be essential for the application of effect-based methods for water quality assessment because they allow to differentiate acceptable from unacceptable water quality. The numerical EBT are preliminary, more work is required to improve the database for their derivation, but already now they are serving in research projects for monitoring purposes.
