Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Rivers, lakes and coastal areas are under pressure from human activities that result in pollution, intensive land use and the degradation of natural habitats. To better manage challenges in this area, an EU-funded project developed methods for assessing and restoring aquatic ecosystems.
