Description of key information

The likely environmental fate of the substance has been assessed based on the substances physico-chemical properties and relevant study data.

The substance is very poorly water soluble/highly insoluble (<0.1 mg/l) and has a high octanol/water partition coefficient (log10Pow>6.5). The low water solubility indicates the substance may persist in the aquatic environment. However the log10Pow>6.5 indicates any dissolved substance may potentially partition out of the aquatic compartment.

The substances adsorption coefficient (log10Koc> 5.63) indicates that dissolved substance has potential for adsorption to sediments or soils and may partition from the aquatic compartment into the sediment or soil compartments.

The substance is not readily biodegradable and no hydrolysis data is available. It is therefore considered that the substance may persist in the aquatic environment.

The substance has some potential for bioaccumulation in aquatic species based onlog10Pow>6.5. However, a further assessment taking into account molecular size and weight, predicted log10Pow values above 10 and predicted BCF values indicatebioaccumulation may not be not significant for the three main substance constituents.

Further simulation studies in soils and sediments are considered to be unnecessary.
