Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
bioaccumulation in aquatic species: fish
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Justification for type of information:
other: calculation
Qualifier:

Guideline:
other: calculation
Key result
Type:
BCF
Value:
34 dimensionless

The bioconcentration factor of 34 was estimated from the experimental log octanol/water partition coefficient of 2.32 using an appropriate regression equation. The result indicates that p-chloroacetophenone will not bioconcentrate in fish and aquatic organisms (HSDB).

Validity criteria fulfilled:
yes
Conclusions:
The calculated bioconcentration factor is reported to 34.
Executive summary:

Although the calculation method is not reported, the data were taken from a peer-reviewed database and are thus considered to be reliable with restrictions.
