Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Bioaccumulation: aquatic / sediment

Description of key information
In accordance with column 2 of REACH Annex IX, the bioaccumulation study in fish does not need to be conducted as the substance can be expected to have a low potential for adsorption (log Kow < 3).
Key value for chemical safety assessment
Additional information
Bioaccumulation of dichloromethane in aquatic species is unlikely in view of its physical and chemical properties (logKow = 1.25).
The theoretical BCF of dichloromethane ranges between 0.91 and 7.9 L/kg (Veith et al., 1980; Lyman et al., 1982; Veith and Kosian, 1983; Bayard et al., 1985). BCF values from a study with carp (CITI, 1986) ranged from < 6.4 - 40 for low and 2.0 - 5.4 for higher exposure concentrations (25 or 250 ug/L).
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.
