Data acquired in laboratory experiments conducted with the crustacean Daphnia magna to characterize Ag bioaccumulation kinetics after exposures to AgNO3 or Ag nanoparticles, 2019-2021
Silver nanoparticles (AgNP) are one type of contaminant that can enter treatment wetlands (Wiesner 2006) and impact the overall treatment efficacy. Grazing by filter feeding zooplankton, such as Daphnia magna, is critical to treatment wetland functioning (Ismail 2019), but the effects of AgNP on zooplankton are not fully understood, especially at environmentally relevant concentrations. In this study, the bioaccumulation kinetics of dissolved and nanoparticulate Ag in D. magna exposed to environmentally relevant Ag concentrations were characterized using isotopically labelled Ag as a tracer.
