Reference
Endpoint:
bioaccumulation: aquatic / sediment
Type of information:
(Q)SAR
Adequacy of study:
other information
Study period:
2012
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
other: Accepted calculation method but report is not available
Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6
Guideline:
other: REACH guidance on QSARs R.6, May 2008
Principles of method if other than guideline:
Calculated with BCF Program BCFBAF v.3.01 included in the Estimation Programs Interface (EPI)-Suite. The estimation methodology is based on the chemical structure of an organic compound and its log octanol-water partition coefficient (log Kow). Depending on chemical structure, structural correction factors are applied.
GLP compliance:
no
Test organisms (species):
other: none, estimated by calculation
Type:
BCF
Value:
517.9 L/kg
Basis:
other: calculation
Remarks on result:
other: regression-based method

Any decomposition of the substance in water is not considered by the program.

Conclusions:
The bioaccumulation factor of 6-Chlor-Chlormethyldien was estimated to be 517.9 L/kg (log BCF 2.714).
Executive summary:

The bioaccumulation factor of 6-Chlor-Chlormethyldien was estimated to be 517.9 L/kg using the BCFBAF model included in the EPI-Suite Programm concluding that the substance has a potential to bioaccumulate in biota.
