Endpoint:
biodegradation in soil: simulation testing
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable
the study does not need to be conducted because direct and indirect exposure of soil is unlikely

Description of key information

The performance of tests for biodegradation in soil is scientifically unjustified. REACH Regulation (EC) No 1907/2006, Annex IX, Sect. 9.2.1.3, Col. 2, states as follows: “9.2.1.3: The study need not to be conducted: - if the substance is readily biodegradable, or - if direct and indirect exposure of soil is unlikely. ” Direct and indirect exposure of the test item ditetradecyl peroxydicarbonate to water and sediment is highly unlikely. The test substance is practically insoluble in water and readily biodegradable.  In addition, low exposure is guaranteed, as no sludge application from STP on soil will be done and aerial deposition is negligible. Thus, simulation testing for biodegradation in soil was considered not scientifically justified.
