Biodegradation in water
In accordance with column 2 of REACH Annex
IX, the simulation test in ultimate biodegradation in water does not
need to be conducted as the substance insoluble in water.
Biodegradation in sediment
The performance of simulation tests for
biodegradation in water and sediment is scientifically unjustified.
REACH Regulation (EC) No 1907/2006, Annex
IX, Sect. 188.8.131.52, Col. 2, states as follows:
“184.108.40.206: The study need not to be
- if the substance is readily biodegradable,
- if direct and indirect exposure of
sediment is unlikely. ”
Direct and indirect exposure of the test
item to sediment and water is unlikely. It can be assumed that upon
contact with sediment and organic matter, the test item undergoes rapid
degradation (hydrolysis) resulting in the formation of respective
degradation products. Furthermore, the test item is not soluble in water
and was considered to be inherently biodegradable. Therefore, simulation
testing for biodegradation in sediment and water was considered not
