Description of key information

EC 903-162-9 is not expected to be bioaccumulative.The high adsorption properties of this substance in combination with the low water solubility will result in very low concentrations, if at all, in the aquatic environment. Once present in the aquatic compartment, due to the high log Kow and log Koc the substance will be bioavailable to aquatic organisms such as fish mainly via feed and contact with suspended organic particles.Due to the high molecular weight range of the main components of the substance and the high octanol/water partition coefficient (> 10), absorption is expected to be very limited.Calculated BCF/BAF values for representative structures of this UVCB, also indicate a negligible potential for bioaccumulation with values far below the trigger value for bioaccumulative substances (< 2000 L/kg).

The gathered information provides strong evidence supporting the assumption that low bioaccumulation potential can be expected for this substance.
