Biodegradation in water and sediment: simulation tests

Description of key information
In accordance with Regulation (EC) No 1907/2006, Annex IX, Section 9.2.1.2 and 9.2.1.4, Column 2, the study does not need to be conducted if the substance is readily biodegradable. Methyl formate and its hydrolytic products are experimentally assessed to be readily biodegradable (see IUCLID Ch. 5.2.1). Therefore, no biodegradation studies in surface water and sediment will be provided for substances.
Key value for chemical safety assessment
Additional information
According to the available hydrolysis study for the substance, Methyl formates' susceptibility to hydrolysis increases with pH as well as with temperature. The hydrolysis half-life ranges from 410 h at pH 4 and 20 °C to less than 1 hour at pH 9 and 25 °C (OECD 111, BASF SE, 2010). Therefore, it can be concluded, that under environmentally relevant conditions (pH 7-9) the rapid hydrolysis will be the major fate process of the methyl formate due to the short half-life in aqueous solution. Therefore, the assessment of the environmental fate of the substance is also performed for the hydrolytic products: formic acid and methanol.
Water:
In accordance with Regulation (EC) No 1907/2006, Annex IX, Section 9.2.1.2, Column 2, the study does not need to be conducted if the substance is readily biodegradable. Methyl formate and its hydrolytic products are experimentally assessed to be readily biodegradable (see IUCLID Ch. 5.2.1). Therefore, no biodegradation studies in surface water will be provided for substances.
Sediment:
In accordance with Regulation (EC) No 1907/2006, Annex IX, Section 9.2.1.4, Column 2, the study does not need to be conducted if the substance is readily biodegradable. Methyl formate and its hydrolytic products are experimentally assessed to be readily biodegradable (see IUCLID Ch. 5.2.1). Therefore, no biodegradation studies in sediment will be provided for substances.
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.
