Figure 3From: Risks from accidental exposures to engineered nanoparticles and neurological health effects: A critical reviewRisk assessment of ENPs to the brain has to be considered for both acute and chronic exposure. The risk due to acute exposure of ENPs is expected to be low based on current knowledge. The lack of appropriate studies for chronic exposure makes it impossible to assess the risk at present. A detailed discussion is given in the text.Back to article page
