Question about input data for metals

Hello,

I recently started to use USEtox (using v.1.1beta). I want to work with copper, so I copied the data for copper into Substance data. Under the Run tab I designated the correct Row number for my input data. But the output data looks incomplete. Under the results tab there are only #NUM! messages in all output boxes. Also, this is the same for e.g. the calculated Fate Factors (altohough number are generated in some cases, e.g. Exposure pathway). I noticed that when I just input some random numbers in the Substance data tab into the fields for rows 5,6,8,9 (which should only have inputs in the case of organics) for copper, results are generated in the Results tab and Fate Factors are calculated etc. 

What am I doing wrong here or am I missing something? Do I somewhere need no input that I'm working with an inorganic for the software to correctly assess the Fate Factors and so on in a correct way?

Best Regards,

Jonas

Please igone the above

Please igone the above question, I hadn't imported the inorganic database properly

Database import

Thank you for your comment!

Importing the substance databases correctly is a pre-requisite for running the USEtox model. Please let us know, if you have further questions.

new to USEtox for metal impacts

Hi

 

I am new to USEtox, and i am now studying its application for metals.

Just a quick question, do I need actual data for using the USEtox model for metals? I mean do I need to use primary data from the field?

 

Thanks!

Input data for metals

Thank you for your question!

Calculating USEtox fate factors for metals requires knowledge of 'effective' solids-water partition coefficients (Kd's and BCF's, i.e. concentration ratios) for sums of all dissolved species in water and all particulate species in equilibrium with water, which one may obtain from field measurements, or by deduction from chemical speciation calculus (for instance via WHAM).
