Nonanal was found to be readily biodegradable under the strict testing conditions of the OECD301F guidelines. In addition, at the concentration used in the test (20 mg/L), it is not inhibitory to micro-organisms.
Further biotic degradation testing such as simulation tests in surface water, sediment and soil is waived. Since nonanal is readily biodegradable simulation tests will provide little additional information as rapid mineralisation in the environment is already assumed.
Assessment of hydrolytic stability was not performed as Nonanal is readily biodegradable and as such, according to Regulation (EC) 1907/2006, it is unnecessary to investigate hydrolysis as a function of pH.
Information on phototransformation in air, water and soil is not available. It is not a standard information requirement under REACH.
The bioaccumulation potential of nonanal has been assessed using screening data (log Kow of 3.4, estimated BCF of 65 to 155 L/kg). The information is deemed sufficient for classification purposes, the PBT assessment and the chemical safety assessment. Therefore bioaccumulation tests are waived.
The Koc for Nonanal was determined to be 692 according to an OECD 121 study.
