Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
Additional information
SrS will not occur as such in the environment. In the terrestrial environment, strontium sulfide dissolves in water releasing strontium cations and sulfide anions. Relevant data on bioaccumulation of sulfide in terrestrial organisms have not been identified. The evaluation of the bioaccumulative potential for sulfide in the aquatic system seems to suggest that sulfide is not largely concentrated by aquatic organisms and presumbably also not accumulated by terrestrial organisms.
However, little information is available on bioaccumulation of strontium in the terrestrial environment by plants and animals.
Heine and Wiechen (1984) reported concentration factors for strontium for pasture plants and the most important agricultural products, namely cereal grain, maize, rape, potatoes, asparagus, beet and beet leaves. Most of the values ranges within an order of magnitude between 0.1 and 1.0 (ratio of Conc./kg fresh plant over Conc./kg dry soil). The medians of all concentration factors of pasture plants and grain were 0.32 and 0.36, respectively.

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.
