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.
