3.2 Calculate the Ecotoxicity Potentials (i) Find the substance’s equivalency factors for the relevant emission route in Table 4.8. Table 4.8 presents equivalency factors EF for around 70 compounds emitted to air, water or soil. (ii) Calculate the ecotoxicity potentials , EP(et) for the relevant compartments by multiplying the magnitude of the emission (or the quantity of substance, Q) with the equivalency factors in ecotoxicity, EF(et) found; EP(et) = Q x EF(et) (4.11) 1

As for nutrient enrichment and acidification, there is no internationally accepted set of equivalency factors expressing substances' potential toxicity in the environment in a way, which can be used in the calculation of potentials for ecotoxicity. There are various proposals for how ecotoxicity can be handled in the LCA, but in the authors' view, their scientific foundation is too weak, or their demands on data are too high to make them operational and usable in 2
