Nanotechnology is a new and fast emerging field that involves manufacture of materials that are less than 100 nm in size in one dimension. Due to their extremely small size, engineered nanoparticles (ENPs) exhibit properties that are vastly different from their’parent’ chemicals, and their reactive surface areas are considerably greater than the corresponding conventional forms. ENPs are currently being used in a variety of consumer products including TiO2 in paints and ZnO in sunscreens. A number of other applications are in the pipeline. It is inevitable that during their manufacture and use, ENPs will be released to the environment. The proliferation of nanotechnology has therefore prompted concerns over their safety when released into the environment
The overall aim of the proposed project is to explore those factors and mechanisms affecting the release, behaviour and uptake of current and future use engineered nanoparticles in the aquatic environment. The results will be used to develop guidance on the design and interpretation of aquatic environmental fate and effects studies.
