Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species, other
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- Estimated data generated using the EPI Suite program developed by the USEPA.
- Qualifier:
- according to guideline
- Guideline:
- other: Modeling database
- Principles of method if other than guideline:
- Prediction done using BCFBAF (v3.01) model
- GLP compliance:
- not specified
- Radiolabelling:
- not specified
- Vehicle:
- not specified
- Test organisms (species):
- other: Fish
- Route of exposure:
- aqueous
- Test type:
- not specified
- Water / sediment media type:
- natural water: freshwater
- Test temperature:
- 25 deg.C
- Reference substance (positive control):
- not specified
- Temp.:
- 25 °C
- Type:
- BCF
- Value:
- 3.162 L/kg
- Basis:
- whole body w.w.
- Calculation basis:
- other: estimated
- Remarks on result:
- other: Non-bioaccumulative
- Validity criteria fulfilled:
- not specified
- Conclusions:
- Using BCFBAF Program (v3.00) model of EPI suite (2018) the estimated bio concentration factor (BCF) for test chemical is 3.162L/kg wet-wt at 25 deg. c which does not exceed the bioconcentration threshold of 2000. Therefore it is concluded that test chemical is nonbioaccumulative in food chain.
- Executive summary:
Using BCFBAF Program (v3.00) model of EPI suite (2018) the estimated bio concentration factor (BCF) for test chemical is 3.162 L/kg wet-wt at 25 deg. c which does not exceed the bioconcentration threshold of 2000. Therefore it is concluded that test chemical is nonbioaccumulative in food chain.

Description of key information
Using BCFBAF Program (v3.00) model of EPI suite (2018) the estimated bio concentration factor (BCF) for test chemical is 3.162 L/kg wet-wt at 25 deg. c which does not exceed the bioconcentration threshold of 2000. Therefore it is concluded that test chemical is nonbioaccumulative in food chain.
Key value for chemical safety assessment
- BCF (aquatic species):
- 3.162 L/kg ww
Additional information
Two studies have been carried out to determine bioaccumulation potential of test chemical and and their results are summarized below.
In first study the bio concentartion of test chemical was determined by using BCFBAF Program (v3.00) model of EPI suite (2018) the estimated bio concentration factor (BCF) for test chemical is 3.162 L/kg wet-wt at 25 deg. c which does not exceed the bioconcentration threshold of 2000. Therefore it is concluded that test chemical is nonbioaccumulative in food chain.
In next study the test chemical is not expected to be bioaccumulative in nature.
By considering resulst of both studies it is concluded that test chemical is not expected to bioaccumulative in aquatic organisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
