An important contribution to getting insight into processes of transport, transformation and accumulation of heavy metals in marine ecosystem lies on the understanding of the strategies developed during evolution by aquatic and terrestrial organisms to maintain equilibrated relations with heavy metal ions in the surrounding environment. This book presents a pioneering study on the workings of metal resistance systems in autotrophic protists and on their ecological significance, implementing the knowledge on chemical and biochemical mechanisms that regulate the bioavailability, accumulation...
