Risk assessment and risk analysis are essential tools to improve safety when dealing with
nanomaterials. The concern about issues of nanoparticles has been growing over the last decade. Uncertainties,
few toxicological data and reliable occupational exposure limits (permissible or recommended)
combined with the increasing amount of new chemicals and materials on nanoscale level demand new
approaches, particularly regarding safety and environmental risk management. Quantitative and qualitative
tools to manage risks are essential to provide a better safe workplace. In this work, a multicriteria
method (AHP – Analytical Hierarchy Process) was used to create a new approach to deal with increasing
complexity of risk assessment of nanocarbon materials.
Keywords: AHP, risk assessment, nanotechnology, nanocarbons, MCDA, health, safety, environment.
