Description of key information

Transport and distribution of strontium 2-ethylhexanoate in the environment are most accurately evaluated by separately assessing the fate of its constituents strontium cations and 2-ethylhexanoate anions.


Strontium: The partitioning coefficient for the sediment compartment of 915 L/kg (log Kd = 2.96) represents the median of 757 paired stream water and sediment samples taken on a grid across Europe within the FOREGS monitoring program (Salminen et al. 2005). The soil-water partitioning coefficient of 65 L/kg (log Kd = 1.81) represents the median of different literature values (Bunzl and Schimmack, 1989; Kamei-Ishikawa et al., 2008; Twinning et al., 2004;Wang and Staunton, 2005; Sheppard and Thibault,1990). The Kd values for water/sediment and water/soil indicate a low potential of strontium to partition into sediment or soil.


2 -Ethylhexanoate:

Based on available data collected according to OECD106 significant adsorption to the solid soil phase is not expected for 2-ethylhexanoate.
