Key value for chemical safety assessment

Additional information

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 on terrestrial organisms. According to Annex I of this regulation, the chemical safety assessment triggers further action when the substance or the preparation meets the criteria for classification as dangerous according to Regulation 1272/2008 or is assessed to be a PBT or vPvB. The hazard assessment of the substance reveals neither a need to classify the substance as dangerous to the environment, nor is it a PBT or vPvB substance.

Furthermore, according to Annex X section 9.4 of Regulation (EC) No 1907/2006, those studies do not need to be conducted if direct or indirect exposure of the soil compartment is unlikely. The substance is considered to be used only industrially. Therefore, direct exposure to the soil compartment is unlikely. Furthermore, an indirect exposure to the soil compartment via sewage sludge transfer is additionally unlikely, since the substance is readily biodegradable according to OECD criteria (MITI, Japan, 1992). For a substance being considered as "readily biodegradable", it can be assumed that it will be biodegraded within the STP process and as a consequence a transfer to the soil compartment is not expected. In addition, adsorption of the substance to the solid soil phase is not expected based on the low n-octanol/water partition coefficient (experimental log Kow = -0.46; BASF AG, 1988). In summary, no significant exposure of the terrestrial compartment is expected. Additionally, due to its low log Kow an accumulation of the substance in terrestrial organisms is not expected.

Therefore, no further tests on terrestrial organisms are provided.
