Description of key information
Measured values for adsorption of EPTAC to soil, sediment or suspended matter are not available, the calculated value for the chlormequat-chloride could serve as a realistic surrogate value for EPTAC (with known limitations).T herefore this surrogate value, sediment-water partition coefficient (Kp sed) 67 l/kg, could describe better the adsorption of EPTAC to sediments than Kp derived from log Pow. Koc (53.8 l/kg) can be used to estimate Kp values for EPTAC in soil, suspended matter and sediment.
Key value for chemical safety assessment
- Koc at 20 °C:
- 53.8
Additional information
As reported in the EU RAR, since measured values for adsorption of EPTAC to soil, sediment or suspended matter are not available, the calculated value for the chlormequat-chloride could serve as a realistic surrogate value for EPTAC (with known limitations). Like in the chlormequat-chloride, the positively charged quaternary nitrogen group in EPTAC is adsorbed by ion exchange mechanism to anionic groups of sediment mineral particles and to organic matter. Therefore this surrogate value, sediment-water partition coefficient (Kp sed) 67 L/kg, could better describe the adsorption of EPTAC to sediments than Kp derived from Log Kow. Adsorption to suspended matter is usually assumed to be two times higher than adsorption to sediment due to two times higher organic carbon content of solids. Based on additional test results, the adsorption of EPTAC is not assumed to correlate highly on the organic carbon content. Thus, the same Kp value (67 L/kg) could be used for suspended matter. Taken the same arguments presented above on sediment it could be possible to use a Kpsoil from chlormequat-chloride (2.4) to describe adsorption of EPTAC to soil. However, as there is information on EPTAC adsorption to STP sludge, an Koc value has been derived for EPTAC from this study. This Koc (53.8 L/kg) can be used to estimate Kp values for EPTAC in soil, suspended matter and sediment. Partition coefficients estimated from the measured Koc for soil, suspended matter and sediment will be used in further calculations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
