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:
1. SOFTWARE
see Mackay, D. 2001. "Multimedia Environmental Models: The Fugacity Approach - Second Edition", Lewis Publishers, Boca Raton, pp. 1-261.

2. MODEL (incl. version number)
Mackay Level I v3.00

3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
- molar mass
- temperature
- water solubility
- vapor pressure
- melting point
- log kow

4. SCIENTIFIC VALIDITY OF THE MODEL
For details see Mackay, D. (2001); Mackay et al. (1996)

5. APPLICABILITY DOMAIN
For details see Mackay, D. (2001); Mackay et al. (1996)

6. ADEQUACY OF THE RESULT
A Level I calculation is not required under REACh but gives a general impression of the likely media into which a chemical will tend to partition and an indication of relative concentrations in each medium.
