Description of key information
Additional information
The ready biodegradability test was peformed to evaluate a non-volatile test substance for its ready biodegradability in an aerobic aqueous medium with microbial activity introduced by inoculation of activated sludge.
The study procedure was based on EEC directive 92/69, C.4 -C, December 1992, and OECD guideline N° 301 B July 17, 1992.
The relative degradation values calculated from the measurments performed during the test period revealed 28% of degradation after 28 days. In conclusion, the substance was not readily biodegradable under the conditions of the modified Sturm test.
The inherent biodegradability study was performed to assess the inherent biodegradability of the test item in an aerobic aqueous medium. The method followed are designed to be compatible with the OECD Guidelines for Testing of Chemicals (1981) No. 302C Inherent Biodegradability; Modified MITI (II) Test and in the MITI Gazette, 19 July 1974 under paragraph 7-1: Method for Testing the Biodegradability of Chemical Substances by Micro-organisms.
The test item attained 91% degradation calculated from oxygen consumption values after 28 days.
The test item can therefore be considered to have exhibited evidence of ultimate biodegradation under the terms and conditions of OECD Guideline No 302C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
