- Аннотация: Experiments with nanoparticles were carried out in aquatic microcosms. For the first time it is shown that the metal (Au) in significant amount bind to the living biomass of the aquatic macrophyte Ceratophyllum demersum (hornwort, rigid hornwort, coontail, or coon's tail). As a result of the binding and/or concentration, the amount of Au in the phytomass increased over the background level by the factor of 430. The amount of gold in the biomass was detected using neutron activation analysis (NAA). The new data added some new information to the modern vision of the polyfunctional role of aquatic organisms (the biota) in the migration of elements in water ecosystems.
