Key value for chemical safety assessment

Additional information

According to Regulation (EC) 1907/2006, Annex IX, Section and, column 2, simulation testing on ultimate degradation in surface water or sediment does not need to be conducted if the substance is readily biodegradable. NOP is readily biodegradable (81% BOD/ThOD in 28 d, OECD 301F, BASF AG, 1992, report no. 91/1784/26/1; see IUCLID Ch. 5.2.1). Therefore, no studies in surface water or sediment will be provided.
