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.
