Description of key information
The performance of a test for bioaccumulation in aquatic species, preferably fish, is scientifically unjustified.
Additional information
The performance of a test for bioaccumulation in aquatic species, preferably fish, is scientifically unjustified.
REACH Regulation No. 1907/2006, Annex IX, Sect. 9.3.2, Col. 2, states as follows:
“9.3.2 The study need not be conducted if:
- the substance has a low potential for bioaccumulation (for instance a log Kow <= 3) and/or a low potential to cross biological membranes, or
- direct and indirect exposure of the aquatic environment is unlikely. ”
Direct and indirect exposure of the test item to water is highly unlikely. Due to the unstable nature of organic peroxides, it can be assumed that upon contact with water and organic matter, the test item undergoes rapid degradation resulting in the formation of respective alcohols and acids. Further, the test item is readily biodegradable. Therefore, TBPND was considered to have no bioaccumulation potential. Using EPIWIN 4.1 a BCF of 925 L/Kg wwt was calculated indicating no potential for bioaccumulation.
