An ecological perspective on nanomaterial impacts in the environment.
Abstract
Growing concerns over the potential for unintended, adverse consequences of engineered
nanoparticles (ENPs) in the environment have generated new research initiatives focused
on understanding the ecological effects of ENPs. Almost nothing is currently known
about the fate and transport of ENPs in environmental waters, soils, and sediments
or about the biological impacts of ENPs in natural environments, and the bulk of modern
nanotoxicogical research is focused on highly controlled laboratory studies with single
species in simple media. In this paper, we provide an ecological perspective on the
current state of knowledge regarding the likely environmental impacts of nanomaterials
and propose a strategy for making rapid progress in new research in ecological nanoscience.

I am an ecosystem ecologist and biogeochemist whose research is principally concerned
with tracking the movement of elements through ecological systems. My research aims
to document the extent to which the structure and function of aquatic ecosystems is
being altered by land use change (urbanization, agriculture, mining) global change
(rising CO2, rising sea levels) and chemical pollution. Ultimately this information
is necessary to determine whether and how ecosystem change can be mi
