wca are long standing partners of SETAC Europe. As in previous years, we have a major presence at the 36th Annual SETAC Europe Meeting to be held in Maastricht. The meeting starts on 17th May and runs through until the 21st May. As always, we will be presenting our work in both platform and poster form, as well as co-chairing three sessions; a full breakdown of wca’s involvement is detailed below.

wca staff will also be available at our exhibition booth through-out the meeting (Booth 81) in the Exhibit Hall. We look forward to discussing our work and presentations with you there.
