Distribution modelling
Administrative data
- Endpoint:
- distribution modelling
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation

Applicant's summary and conclusion
- Conclusions:
- According to the calculated distribution to compartments yttrium chromite mainly spread to water and soil.
- Executive summary:
According to the fugacity model, Level III, the distribution of yttrium chromite to air - water - soil - sediment is 0.000179 - 20.4 - 79.5 - 0.0974 %. These results show, that the majority retains in water and soil, while there is just little available in the air and sediments.
