Deriving characterization factors on freshwater ecotoxicity of graphene oxide nanomaterial for life cycle impact assessment

Purpose Graphene oxide (GO) nanomaterial has found wide potential industrial applications, but its life cycle environmental impact is not fully understood mainly because of lack of characterization factors (CFs) for the life cycle impact assessment. In this paper, we report the derivation of CF for freshwater ecotoxicity of GO based on the USEtox method.
