Julián Blasco, Ph.D., is presently Director of the Institute of Marine Sciences of Andalusia belonging to the Spanish National Research Council. He received his doctorate in Chemistry (1985) from the University of Seville (Spain). He is responsible for the research group "Ecotoxicology, Ecophysiology and Biodiversity of Aquatic Systems". His research focuses on the legacy and emergent (pharmaceuticals and nanoparticle) pollutant effects on aquatic species and biogeochemistry of trace metals in the marine environment.Ilaria Corsi, Ph.D., is presently Adjunct Professor of Ecotoxicology at the University of Siena. She received her doctorate in Environmental Biology (2001) from the University of Siena (Italy). She is responsible for the research group "Ecotoxicology and Biological Monitoring" and head of the section of "Ecotoxicology of emerging contaminants and nanomaterials". Her research focuses on legacy and emerging contaminants including nanomaterials and their environmental behaviour and biological effects from organism up to population level.
