Theme 3: Ecosystem Functional Responses to Nanomaterials

Ecosystem Functional Responses To Nanomaterials elucidates the effects of manufactured, natural, and incidental nanomaterials in inherently complex natural 'real' ecosystems and the services they provide. The impacts of nanomaterials in aquatic and terrestrial ecosystems over a range of length-scales and complexity is studied using macrocosms, microcosms, and bench-scale experiments. These ecosystems, that include aquatic flow-through and terrestrial microcosms are shared experimental facilities accessible by all members of the Center and include instrumentation for the analysis of biogeochemical transformations and quantification of inputs and outputs.
