Additional information

The log Koc value (3.844) of the substance indicates, that the substance is slighlty mobile, i.e. that it does adsorbs rather strong to soils or sediments according to FAO mobility classification.

In a distribution study, the removal of the substance during sewage treatment was estimated using the STPWIN™ module of EPI Suite™ v.4.11. STPWIN™ uses several outputs from EPI Suite™. This program predicts the removal of a chemical in a typical activated sludge-based sewage treatment plant. The program assumes a standard system design and set of default operating conditions. The results show that 90.96% of the substance was removed during wastewater treatment by adsorption to sludge. I.e. less than 10% will enter surface waters via STP effluents.

Hence, significant contamination of environmental compartments like surface waters, sediment, soil and groundwater via horizontal and vertical transport is not expected.

The very low vapour pressure of the substance indicates that the risk of environmental contamination via the air is very low.

Hence, the issue of transport and distribution in all compartments of the environment is of no concern.
