Description of key information

Additional information

The substance is not readily biodegradable according to an OECD TG 301D study. The substance is a gas at room temperature. In addition, it is likely to partition to the water rather than to the sediment and soil compartments as it has a relatively low partition coefficient (log Kow = 2.2) and adsorption coefficient (Koc = 146 L/kg). Furthermore, the high vapour pressure (1065 hPa) and Henry’s law constant (4.64E+03 Pa*m3/mol) suggest that the substance will volatilize rapidly from water and partition to the air. With the current biodegradation status of the substance, the CSA indicates that the risks in the water, sediment and soil compartments are controlled and no further information will have to be provided. Based on all the information, the biodegradation simulation tests in water, sediment and soil are waived.
