Endpoint:
bioaccumulation in sediment species: invertebrate
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3
Endpoint:
bioaccumulation in aquatic species: fish
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3

Description of key information

In accordance with section 9.3.2, column 2 of Annex IX to Regulation (EC) No 1907/2006 (REACH) the study on bioaccumulation in aquatic organisms (preferred species fish) is scientifically not necessary since the substance has a log Kow < 3. Regarding the log Kow, accumulation of the test substance in organisms is not to be expected.

Additional information

Waiving justification


In accordance with section 9.3.2, column 2 of Annex IX to Regulation (EC) No 1907/2006 (REACH) the study on bioaccumulation in aquatic organisms (preferred species fish) is scientifically not necessary since the substance has a log Kow < 3. In an experimental study the log Kow of the substance was determined to be 0.68 at 25 °C (see IUCLID section 4.7), which is clearly below the indicated threshold value for bioaccumulation potential. Further, based on the structure and physicochemical properties of the substance the potential to cross biological membranes is low. Therefore, the study on bioaccumulation in aquatic organisms is regarded scientifically not necessary and was waived.
