Description of key information

Two studies data are available for the terrestrial bioaccumulation of strontium by terrestrial plants indicating that strontium has a low potential to bioaccumulate in plants.

Key value for chemical safety assessment

Additional information

Bioaccumulation in terrestrial plants

The soil-plant bioaccumulation factors were measured for stable strontium, 85Sr and 90Sr. Heine and Wiechen (1984) reported in their field study bioaccumulation factors in the range of 0.04 to 0.14 for stable Sr in pasture plants at different locations whereas BAF values of Sr90 in pasture plants ranges from 0.17 to 0.94 and in vegetables and grain from 0.07 to 1.48. The BAF values of Twinning et al. (2004) are based on 85Sr accumulation by different plant species in spiked tropical red earth and range from 0.44 in Sorghum to 63 in mung bean leafs. In sum, strontium bioaccumulation in terrestrial plants appears to be low.
