in the context of the Fulbright program. Her research has been focused on the toxic effects of pesticides to aquatic and soil organisms, considering both single and mixture exposures to these environmental contaminants widely used in the agricultural practices to increase food production. The applicability of mixture toxicity models as a tool to design environmental friendlier formulations of pesticides has been her general research line. The regulation that controls the use of pesticides is also one of her main interests. The understanding and improvement of the Environmental Risk Assessment schemes that are used to assess the risk that these products can pose to the environmental and human health is imperative and gave rise to the writing of this paper. Joana Luísa Pereira is a researcher at the Department of Biology and the Centre for Environmental and Marine Studies (CESAM) University of Aveiro since her PhD in Biology, awarded in 2008. Her main research lines are within the fields of ecotoxicology and environmental risk assessment, with strong links to limnology (including under regulatory frameworks such as the EU-Water Framework Directive), extreme environments, invasive species and aquatic nuisance management and education for sustainability. She has been investing in the development of new approaches and testing platforms towards the improvement of prospective and retrospective environmental risk assessment routines, always aiming for the increase of environmental realism and/or better prediction capabilities. Pesticides, metal elements and designer chemicals have been the major contaminants focused within this prospective context. She published so far more than 60 SCI papers, collecting more than 800 citations.
