Additional information

The log Koc of the EEA ion of EEA-NH4 could not be determined using the HPLC-method. Therefore, the organic carbon-water partitioning coefficient (Koc) was calculated from the octanol-water partition coefficient (log Kow) using the equation from EUSES (predominantly hydrophobics). The calculated log Koc is 11.4 L/kg (log value = 1.06) from a log Kow of 1.18. This predicted value is used in the assessment.

Further studies on transport and distribution of EEA-NH4 in the environment are not available.
