Description of key information
Additional information
In biodegradation tests (ECB, 2000; Scholz et al., 1996; Chang et al., 2005; Ziogou et al., 1981; Howard et al., 1984) clearly, the 10 day window has been reached, and DBP can be considered as readily biodegradable.
DBP is biodegradable in natural waters and sediments, with an estimated half-life in the range of 1 to 17 days (Johnson and Lulves, 1975; Johnson et al, 1984; Walker, 1984; Shelton et al., 1984).
Study for biodegradation in soil according to column 2 ANNEX IX of REACH Regulation (EC) No 1907/2006 not need to be conducted if the substance is readily biodegradable and DBP is readily biodegradable. Chang et al. studied the biodegradation of DEHP and DBP in two types of compost or in compost amended soil. This study was not enough detailed and performed under controlled parameter (no field study) and on Asiatic soil and compost. Therefore, this study is considered as not assignable. It however gives indication that DBP is biodegradable in soil with short half-life consistent with other studies.
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.
