The present study used a standardized Ag nanomaterial (NM‐300K, 20 nm) supplied with a stabilizing agent. The aim was to investigate the behavior of Ag nanomaterial in an estuarine‐like medium at 2 salinities (15 psu and 30 psu). Uptake as well as sublethal effects of Ag nanomaterial (10 μg Ag/L), its stabilizing agent, and AgNO3 (10 μg Ag/L) were assessed in the clam Scrobicularia plana, after 7 d of exposure. The release of soluble Ag from Ag nanomaterial in the experimental media was quantified by using diffusive gradient in thin films and ultrafiltration. A multibiomarker approach was employed to reveal responses of clams at subindividual and individual levels. The bioaccumulation of Ag was significantly greater at 15 psu versus 30 psu, which could be explained by differences in Ag speciation. In conclusion, the present study showed different impacts of Ag nanomaterial that were not always explained by the release of Ag ions in clams at both salinities; such impacts were particularly characterized by induction of oxidative stress, cell damage, and impairment of energetic levels. Burrowing of clams was affected by the stabilizing agent depending on the salinity tested, with stronger effects at 15 psu. Finally, the present study highlighted salinity‐dependent changes in the physiology of estuarine bivalves. Environ Toxicol Chem 2016;35:2550–2561. © 2016 SETAC

Several authors working on biomarkers in ecotoxicology use the term adaptation. However, numerous papers define adaptation as synonymous of resistance (Booth and Biro 2008; Demmig-Adams et al. 2008), and resistance is frequently used in the scientific literature as a synonym for tolerance (Forbes and Forbes 1994). Several authors have tried to clarify these terms. The definitions proposed by different authors may be different, and none is currently generally adopted (Lotts and Stewart 1995; Morgan et al. 2007). Today, most authors use the term ...

How can? It seems to be greater when a book can be the best thing to discover. Books now will appear in printed and soft file collection. One of them is this book aquatic ecotoxicology advancing tools for dealing with emerging risks. It is so usual with the printed books. However, many people sometimes have no space to bring the book for them; this is why they can't read the book wherever they want.
