Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
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 non-bioaccumulative 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 non-bioaccumulative in food chain.

Additional information

Predicted data study for target chemical and experimental studies for its read across chemical have been reviewed from different sources and their results are summarized below.

The first study was predicted data study in this BCFBAF Program (v3.00) model of EPI suite (2018) was used to estimate bio concentration factor (BCF) for test chemical and estimated BCF value was 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 non bioaccumulative in food chain.

Next study was experimental study reviewed from authoritative database (HSDB, 2018) in this study the BCF value of test chemical was estimated to be 3 dimensionless by using log Kow of 0.91 and regression derived equation and it is far less than 2000 criteria so it is concluded that test chemical is non bioaccumulative.

Last study was also experimental study from authoritative database (HSDB, 2018) in this the BCF value The BCF value of test chemical was estimated is 6.0 dimensionless by using log Kow of 1.88 and regression derived equation and it is far less than 2000 criteria so it is concluded that test chemical is non bioaccumulative.

By considering results of all the studies mentioned above it can be concluded that test chemical is non bioaccumulative in food chain.
