Additional information
In accordance with column 2 of REACH Annexes IX and X, terrestrial studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely. Direct exposure to soil is not likely, since the substance is not intentionally applied to soil. Indirect exposure to soil is also not likely since the substance is readily biodegradable and has a low adsorption potential (log Koc <<3). Further, as the substance is of low toxicity to STP microorganisms (OECD 209: EC50 (3 h) = 470 mg/L), the potential for toxicity to soil micro-organisms is assumed to be low. Based on the low aquatic toxicity (EC/LC50 > 1 mg/L) the substance was assigned to soil hazard category 1, according to the ITS as described in ECHA Guidance on Information Requirements and CSA, R.7c. Accordingly, the EPM method was applied to assess the hazard for soil organisms. In conclusion, soil micro-organism toxicity testing is not required.
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.
