Description of key information

The bioconcentration factor (BCF) was estimated by three QSAR models:
- BCFBAF v3.01 module of EPI Suite (v4.0) - Regression-based estimate
- BCF-BAF v3.01 module of EPI Suite (v4.0) (including biotransformation) - Arnot-Gobas lower trophic level
- A model described in Technical Guidance Risk Assessment (European Chemicals Bureau, 2003) - Part II, Chapter 3.8, equation (74) p. 126
The estimated fish BCF of (-)-beta-pinene is 838.0 L/kg (geometric mean of results of three QSAR models: 1140.2 L/kg, 1125.0 L/kg, 383.1 L/kg).

Key value for chemical safety assessment

BCF (aquatic species):
838 L/kg ww

Additional information

ECHA Guidance (chapter R.7.c) recommends to calculate the BCF 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 bioaccumulation and can be used as input parameter for environmental risk assessment.
