Metal carboxylates are substances
consisting of a metal and a carboxylic acid. Based on the solubility of
strontium neodecanoate in water (8.47 g dissolved Sr/L at pH 8.4
corresponding to 45.07 g strontium neodecanoate/L), a complete
dissociation of strontium neodecanoate resulting in strontium and
neodecanoate ions may be assumed under environmental conditions.
Soil-plant bioaccumulation factors are
available for stable strontium, 85Sr and 90Sr. Heine and Wiechen (1984)
reported 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 leaves. In sum,
strontium bioaccumulation in terrestrial plants appears to be low. No
terrestrial bioaccumulation data for neodecanoate could be identified.
Therefore, strontium neodecanoate is expected to have a low potential to
bioaccumlate in terrestrial organisms.
