The use of nanoparticles in medicine, industrial, and other applications has triggered an interest in their potential. This book explores the use of nanoparticles related to their occurrence in the environment, their impact on biota in aquatic systems, application of new methodologies, and changes associated with new global scenarios. The book also covers the bioaccumulation and internalization of nanoparticles as key aspects to assess their uptake and discusses the methodologies for testing ENPs ecotoxicity at different trophic levels.

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.
