Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Lithium salts are not considered to bioaccumulate.
Additional information
Lithium salts are not considered to bioaccumulate. The anionic part of the lithium salts is either natural or chemically indistinguishable from natural substances. Anionic parts like carbonate, chloride or nitrate can be found ubiquitous in nature. Thus, only data on the bioaccumulation potential of the lithium component are presented here. The highest BCF/BAF was determined by Antonkiewicz et al. (2017) for terrestrial plants under hydroponic conditions with values between 9 and 16 over the different dosing groups. Barber et al (2006) determined a BCF of around 8 L/kg in freshwater fish. Other publications indicate BCF/BAF values of 1 (Karlsson et al. 2002) or below 1 (Pokorska et al., 2012). Kastanek (2015) concluded in his study with three different algae species that the bioaccumulation potential of lithium is neglible.
Recalculation of the highest BAF/BCF values of the evaluated literature resulted in a BCF of 43 L/kg and a BAF of 85 for lithium carbonate. Thus, lithium carbonate is not considered as bioaccumulative.
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.
