Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: invertebrate
- Data waiving:
- other justification
- Justification for data waiving:
- the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with Column 2 of REACH Annex IX, the study does not need to be conducted since the substance has a low potential for bioaccumulation (log Pow < 3). - Endpoint:
- bioaccumulation in aquatic species: invertebrate
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Principles of method if other than guideline:
- Calculation by EPI-Suite, EPA (USA) / BCFBAF v3.01
- GLP compliance:
- no
- Type:
- BCF
- Value:
- 48.55 L/kg
- Basis:
- other: estimated by BCFBAF v3.01 (EPI Suite)
- Remarks on result:
- other: Log BCF from regression-based method = 1.686
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The estimated bioaccumulation factor for 2-methylcyclohexyl acetate was 48.55 L/kg wet-wt (BCFWIN v3.01).
- Executive summary:
The bioaccumulation factor was estimated by the calculation method EPI Suite / BCFWIN v3.01. The BCF for 2 -methylcyclohexyl acetate was calculated to be 48.55 L/kg wet-wt (BCFWIN v3.01). The Log BCF from regression-based method was 1.686.
