ENVIRONMENTAL EXPOSURE ASSESSMENT<br />

stage the substance is recovered this amount should be added to the tonnage of the relevant lifecycle<br />

stages. Note that IMPORT <strong>and</strong> EXPORT refer to the EU, not Member States within the EU.<br />

Explanation of symbols<br />

TONNAGE = PRODVOL + IMPORT - EXPORT (4)<br />

PRODVOL production volume of substance [tonnes . yr -1 ] data set<br />

IMPORT volume of substance imported [tonnes . yr -1 ] data set<br />

EXPORT volume of substance exported [tonnes . yr -1 ] data set<br />

TONNAGE tonnage [tonnes . yr -1 ]<br />

The release (in tonnes.yr -1 ) per stage of the life-cycle <strong>and</strong> to every environmental compartment is<br />

calculated with the equations given in Appendix IA <strong>and</strong> denoted by RELEASEi,j (where i is the<br />

stage in the life-cycle <strong>and</strong> j is the compartment):<br />

i stage of the life-cycle j compartment<br />

1 production a air<br />

2 <strong>for</strong>mulation w water<br />

3 industrial/professional use s industrial soil (regional only)<br />

4 private use<br />

5 service life<br />

6 waste disposal (including waste treatment <strong>and</strong> recovery)<br />

The following table presents the variables used as input <strong>for</strong> the emission tables in Appendix I, <strong>and</strong><br />

the releases which are the output from emission tables <strong>and</strong> the calculation routine of Appendix I.<br />

Input<br />

MAINCAT main category (<strong>for</strong> existing substances) [-] data set<br />

PRODVOL production volume of substance [tonnes . yr -1 ] data set<br />

VP vapour pressure [Pa] data set<br />

BOILPT boiling point (<strong>for</strong> some estimations) [°C] data set<br />

For each stage other than production, the losses in the previous stage are taken into account (see<br />

calculation in Appendix I). Releases during production are not taken into account in the other<br />

stages, as generally, these releases will not have been considered in the reported production<br />

volume. In certain cases this might lead to total releases exceeding 100%. The rapporteur must<br />
