Description of key information

For the purposes of environmental and exposure assessment, the EUSES 2.1.1 model was used to predict environmental partitioning in waste water treatment plant for the constituent blocks of DTO. Distribution is calculated using the SimpleTreat sewage treatment model, based on the physicochemical and biodegradation properties. These distributions are also indicative of the distribution in the wider environment.

The estimated distribution is shown in Table 4.4.
