Description of key information
Biodegradation:
Inherently biodegradable (WoE, OECD 302 B, OECD 301 D)
Transport and distribution / Bioaccumulation
Adsorption / desorption and bioaccumulation potential is expected to be low (log Kow < 3).
Additional information
Weigth-of-evidence from two reliable studies on inherent biodegradation and one study on ready biodegradation consistently shows that that 2 - chlorobenzaldehyde is (at least) inherently biodegradable. With respect to environmental transport and distribution, information on adsorption/desorption is the only information required for substances up to 100 t/a. According to Annex VIII (section 9.3.1) of Regulation (EC) No 1907/2006, adsorption/desorption screening is not required if the substance has a "low octanol water partition coefficient". Respective criteria in the "Guidance on information requirements and chemical safety assessment - Chapter R.7a: Endpoint specific guidance" (May 2008) are met by o-chlorobenzaldehyd. Asoprtion/desorption testing therefore is not considered necessary.
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.
