Description of key information
No studies on terrestrial organisms are available for DMEE (CAS 1704-62-7). In Annex X section 9.4 of Regulation (EC) No 1907/2006, it is laid down that tests on terrestrial organisms shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on terrestrial organisms. The choice of the appropriate tests depends on the outcome of the chemical safety assessment. In particular for substances that have a high potential to adsorb to soil or that are very persistent, the registrant shall consider long-term toxicity testing instead of short-term. According to Annex X section 9.4 of Regulation (EC) No 1907/2006, these studies do not need to be conducted if direct or indirect exposure of the soil compartment is unlikely. The test substance is not supposed to be directly applied to soil. Indirect exposure to soil is unlikely to occur in significant dimensions since, if any, relevant amounts of the substance will reach industrial STPs rather than domestic STPs. Sludge of industrial STPs will usually not be applied on agricultural soil but will be incinerated. The available data indicate that the substance (and its predicted metabolites) is not very adsorptive (log Koc < 3, log Kow < 3; see IUCLID chapter 5.4.1) or bioaccumulative (log Kow < 3; see IUCLID chapter 5.3.1). The distribution modelling indicates that the main target for DMEE will be water (99.9%; see IUCLID chapter 5.4.3). Therefore, exposure of terrestrial organisms is unlikely. In addition, the substance (and its relevant metabolites) is not a PBT or vPvB substance and the risk assessment results in Risk Characterization Ratios (RCRs) far below 1 for all compartments. Consequently, no test on soil organisms is performed. The equilibrium partitioning method has been used to assess the hazard potential for soil organisms.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
