Description of key information

Bioaccumulation: aquatic/sediments:

Using BCFBAF Program (v3.00) model of EPI suite (2018) the estimated bio concentration factor (BCF) for test chemical is 1985 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.

Additional information

Bioaccumulation: aquatic/sediments:

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

The first was done by using BCFBAF Program (v3.00) model of EPI suite (2018) in this study the bio concentration factor (BCF) for test chemical was estimated to be 1985 L/kg wet-wt at 25 deg. c

Further following both the studies were reviewed from authoritative database (HSDB)

The bioaccumulation factor (BCF) value was calculated using a log Kow of 4.35 and a regression-derived equation. The estimated BCF (bioaccumulation factor) value of test chemical was determined to be 450 dimensionless.

In another study the bioaccumulation factor (BCF) value was calculated using an estimated log Kow of 4.39 and a regression derived equation. The BCF (bioaccumulation factor) value of test chemical was determined to be 1300 dimensionless.

By considering result of all the studies mentioned above it is concluded that BCF value of test chemical may be in range of 450 -1985 dimensionless which does not exceed the bioconcentration threshold of 2000, indicating that the chemical can be considered to be non-accumulative in aquatic organisms.
