The adsorption coefficient (log Koc) was estimated by three QSAR models: - KOCWIN v2.00 in EPI Suite (v4.0) - MCI method using log Kow- KOCWIN v2.00 in EPI Suite (v4.0) - log Kow method- A model described in Technical Guidance on Risk Assessment (European Chemicals Bureau, 2003) - Part III, Chapter 4, table 4, equation for non hydrophobic substancesThe estimated Koc of (-)-beta-pinene is 3317 L/kg (geometric mean of three QSAR models: 1020 L/kg, 6850 L/kg and 2082 L/kg).
ECHA Guidance (chapter R.7.a,paragraph
R.7.1.15) recommends to calculate the Koc endpoint value as
the geometric mean of results obtained by means of QSAR models.
This geometric mean value is
considered as the endpoint defining the substance potential for
adsorption and can be used as input parameter for environmental risk
