INCLUDING NANOPARTICLE MIXTURES IN HUMAN HEALTH RISK ASSESSMENT

摘要

This Learned Discourse comments on the assessment of carbon nanoparticles (NPs: fullerenes and carbon nanotubes) from air under current human health risk assessment (HHRA) procedures, and presents the case for considering simultaneous exposures of different NPs. A modification in the steps for conducting HHRA of NPs is suggested. Specifically, for both exposure and effects assessments, the possible co-occurrence of NPs and combined toxicity should be considered.
