Time-dependent CFs for metals

Hello USETox team,

I would like to distinguish the LCA of my temporal LCI over time (currently the metal emissions are calculated dynamicall). How can I determine the LCIA in USETox? At least if the model is steady state, is it possible to parameterize the CFs, as if it has different values?

Regards,
Raka

Dynamic USEtox

To apply time-dependent characterization factors for metals (or other substances), the environmental fate dynamics in USEtox need to be modeld as function of time. For this purpose, a dynamic version of USEtox, consistent with the steady-state version and fully matrix-based, has been developed and is currently being tested. This version will be released soon along with a short article describing the mathematical framework of the dynamic version. Once the testing phase is finalized (within the next couple of months), the dyamic version of USEtox will be formally released at http://usetox.org.
