Description of key information

67-43-6,DTPA-H5,

log Koc: 3.57 L/kg (Estimate from MCI) or log Koc: :  -2.76  L/kg (Estimate from Log Kow).  The estimated log Koc values are less than the threshold value/at the borderline value of 3 indicating some adsorbing potential for this compound. However, since this compound is mostly negatively charged at relevant environmental pH values, reducing its chances of being adsorbed to soil minerals/humic acids.

Key value for chemical safety assessment

Additional information

See: 67-43-6, Adsorption / desorption, Zvinavashe, 2010, Calculated octanol-water partition coefficient (log Kow) and organic carbon partition coefficient (log Koc)

A computional method has been used because the substance does not sufficiently adsorb onto organic material due to its polarity and therefore high solubility in water.
