Distribution modelling
Administrative data
- Endpoint:
- distribution modelling
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- The fugacity model estimates the partitioning of organic substances between the compartments air, soil, water and sediment in the environment. The model a well-accepted calculation tool and is part of EPI Suite (US EPA 2000-2008).
