Nanotechnology is nowadays fully used in all sorts of different products, ranging from cosmetics to electronics. This fact arouses new concerns related to health, environment and safety. Therefore it is important to identify all impacts the use of this technology might have. This project aims to recognize the advantages and disadvantages of the Cerium (IV) Oxide use, focusing mainly on the utilization as a catalyst reducing both fuel consumption and emissions. In order to evaluate the risk and benefits of CeO2 usage the advantages and drawbacks were identified and the Swiss Precautionary Matrix used for completing a preliminary risk assessment.
