As Laboratory of Environmental Chemistry and Biochemistry and Laboratory of Aquatic Toxicology and Ichthyopatology, we attend the SETAC Europe 25th Annual Meeting, which was held in Barcelona, Spain, from 3-7 May 2015. The conference was focused on ‘Environmental protection in a multi-stressed world: challenges for science, industry and regulators’. T. Randak, V. Zlabek, G. Federova, V. Burkina, O. Golovko, S. Sakalli and V. Kumar presented their various experimental works in poster and oral presentations. Participation in the conference was intense and we had the opportunity to arrange future international collaborations.
