Part 2a: Guide 79

Example (for baseline)

impact category terrestrial 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 terrestrial ecotoxicity potential (TETP) for each emission of a
toxic substance to air, water and/or soil (in kg 1,4-
dichlorobenzene equivalents/kg emission)
unit of indicator result kg (1 ,4-dichlorobenzene eq)
