How is the AEGL concept implemented ?
These applications, however, have not yet officially been implemented in Germany. In this context, some interesting questions arise, some of which are:
- Which effect level (AEGL-1, AEGL-2, AEGL-3) is used in the individual areas of regulation?
- How is the AEGL concept linked to a specified action level?
- How is the expected immission profile in the chemical concentration optimally brought to congruence with the AEGL values for different exposure periods?
- Is the concept of AEGL as threshold concentrations compatible with, e.g., analytical methods producing mean values of defined periods?
- How is the concept of single substance assessment put into practice in the case of complex mixtures resulting from fire?
- How is harmonization of the AEGL application reached in the case of transboundary emergencies ?
Integration of these aspects into the AEGL concept is currently the subject of detailed discussions in Germany. Appropriate concepts, however, cannot yet be reported.
