Reference
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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING:
In accordance with column 2 of REACH Annex IX, the bioaccumulation in aquatic species test ( required in section 9.3.2) does not need to be conducted as the substance has a low potential for bioaccumulation (a log Kow < 3) as it is an inorganic substance.

Description of key information

Data waiving: The aquatic/sediment bioaccumulation study does not need to be conducted as the substance has a low potential for bioaccumulation (a log Kow<3) as it is an inorganic substance.


 


Estimated key value for chemical safety assessment:


logBCFfish = 0.85 x log Kow - 0.70 → BCF fish = 0.0112 L/kg ww


(calculated from the formula for substances with log Kow<6 included in page 246 of the TGD on Risk Assessment, Part I)

Key value for chemical safety assessment

BCF (aquatic species):
0.011 L/kg ww
