Lead: Engineered nanomaterials are intensively discussed in science and regulatory bodies. Many aspects of their fate in the environment and their toxic effects and risks are still open. It is also not yet possible to detect then at trace concentrations in natural system such as water, sediments or soils. In order to estimate how relevant nanomaterials are for the environment and if risks to organisms can occur, it is necessary to determine their environmental concentration. This is done by the use of modeling in this project.Project description: The goal of this project is to quantify the flows of engineered nanomaterials to the environment and describe their behavior in the environment by applying material flow and environmental fate models. Based on production and use of six important nanomaterials (nano-silver, nano-titanium dioxide, nano-zinc oxide, carbon nanotubes, fullerenes and nano-gold) and their behavior in technical systems, we developed material flow models which estimate the flows to the environment for Switzerland and the EU. The mechanistic modeling of the behavior of the na-nomaterials in natural waters has shown that the binding of the nanomaterials to natural parti-cles is the most important process affecting their fate in water. Because the data to parameterize the models were not available, experimental studies with nanomaterials and natural particles were performed.Regulators and scientists have an urgent need for environmental concentrations of nanomaterials in order to base the discussion on possible environmental risks on a solid foundation. Our re-search project provides these data and thus helps to put the discussion on risks and chances of nanomaterials in the environment on a scientific basis.
