Example (for baseline)

impact category marine aquatic ecotoxicity
LCI results emissions of toxic substances to air, water and soil (in kg)
characterisation model USES 2.0 model developed at RIVM, describing fate, exposure
and effects of toxic substances, adapted to LCA
category indicator predicted environmental concentration/predicted no-effect
concentration
characterisation factor marine aquatic ecotoxicity potential (MAETP) for each emission
of a toxic substance to air, water and/or soil (in kg 1,4-
dichlorobenzene equivalent/kg emission)
unit of indicator result kg (1,4-dichlorobenzene eq)
