The results of the site-dependent characterisation are shown in Table 8.3.
Aquatic eutrophication impacts as N-equivalents from either product system with site-dependent characterisation of key process emissions.
Plastic component 9.2 Site-dependent characterisation hardly influences the size of the terrestrial eutrophication impacts.
Photochemical ozone impacts from either product system with site-dependent characterisation of key process emissions.
Factors for site-dependent characterisation of photochemical ozone formation impacts on vegetation and human health Country Vegetation.
Table 5.1. Factors for site-generic, and for site-dependent characterisation in 0.01 m2 unprotected ecosystem/g.
Site-dependent characterisation reduces the size of the aquatic eutrophication impact with N slightly and reduces the dominance of the zinc component.
Factors for site-generic characterisation, and for site-dependent characterisation of eutrophication of inland waters and marine waters.
Site-dependent characterisation reduces the size of the human toxicity impact via air for both components but strengthens the dominance of the zinc component.

Site-dependent characterisation Table 4.2 shows that the predominant contributions to the site-generic acidification impact are caused by emissions of SO2 and NOx.
This procedure can be seen as a sensitivity analysis-based reduction of those uncertainties in the site-generic impact which are posed by refraining from site-dependent characterisation.
Even if the site-dependent characterisation was performed for all the remaining processes in the product system, the result would thus not change significantly.
In order to shed some light on the influence of the potential spatial variation, site-dependent characterisation is performed for those processes that contribute the most to the site-generic impacts.
Site-dependent characterisation Table 5.2 shows that the predominant contributions to the site-generic terrestrial eutrophication impact are caused by the emissions of NOx.
If the ozone impact on human health turns out to be decisive, the site-dependent characterisation must be performed for an additional part of the processes in the plastic component's product system.
Site-dependent characterisation Table 6.3 shows that the predominant contributions to the site-generic aquatic eutrophication impact are caused by the emissions of NOx to air.
Typical life cycle inventories already provide the only additional information which is required for site-dependent characterisation, namely the geographical region where the emission takes place.
Site-dependent characterisation Table 8.2 reveals that the predominant contributions to the human toxicity impact via air are caused by SO2, NOx, Pb and(for the zinc component) Cd.
Though the geographical region of release is often known, this information will not always be available, andfor some applications it is also preferable to refrain from site-dependent characterisation.
Site-dependent characterisation Table 9.3 reveals that the predominant contributions to the ecotoxicity impact are caused by Cd and Zn to air and(for the zinc component) Zn to air.
Step 1 For each of the sub categories calculate the site-generic photochemical ozone formation impact as described in the previous section, and on this basis identify the processes with the dominating contributions ordecide to do site-dependent characterisation for all processes.
A site-dependent characterisation removes the major part of this uncertainty for all impacts for the zinc component and for all impacts except photochemical ozone impact on human health for the plastic component.
As stated in the ozone example in Section 7.9, the ozone impact on human health from the plastic component still comprises a significant potential for spatial variation, andtherefore no conclusion can be drawn for this impact category without extending the site-dependent characterisation to comprise additional key processes.
Site-dependent characterisation Table 7.2 and 7.3 show that the impacts on vegetation as well as on human health are dominated by the contribution from NOx, while an emission of unspecified VOCs is also noticeable.
Therefore, a site-dependent characterisation is performed for those processes that contribute the most to the site-generic impacts in order to reduce the spatially determined uncertainty and strengthen the conclusion.
Even if the site-dependent characterisation were performed for all the remaining processes in the product system, the result will thus not change significantly, given their modest share in the total and the standard deviation.

Site-dependent characterisation Table 5.2 shows that the predominant contributions to the site-generic terrestrial eutrophication impact are caused by the emissions of NOx.A minor contribution from NH3 is negligible in the overall impact.
