A PhD scholarship is available in the Section on Environmental Fate & Effect of Chemicals at DTU Environmental Engineering (DTU Environment) within the topic of environmental regulation and risk assessment of nanomaterials. The specific focus of the advertised scholarship is on analysing pros and cons of existing regulation of nanomaterials and on identify legal, technical and scientific limitations when it comes to considering the formation of eco-coronas on nanomaterials. The work will furthermore include analysis of the technical guidance provided by European governmental agencies that support the implementation of existing regulations. The research combines elements of environmental engineering, materials science, policy-analysis, regulation and environmental law. The overarching context is environmental regulation and risk assessment and management of chemicals and nanomaterials in the environment.
