Description of key information

The adsorption potential of the substance was investigated according to OECD TG 121 using the HPLC method under GLP.  Under the conditions of the test, the major components of the substance were found to have log10 Koc values between 4.0 and 4.2. 

A Henry's law constant was calculated using the equation from EUSES. Using a molecular weight of 246 g/mole, and the experimentally determined vapour pressure of 0.06 Pa (at 25 °C) and water solubility of 5.142 mg/L (at 25 °C), the Henry's Law constant at 25°C and at environmental temperature (12°C) is calculated to be 2.868 and 1.374 Pa·m³/mol, respectively. This Henry's Law Constant shows that volatilisation is of minor importance in the environmental behaviour of the substance (see also distribution modelling).

Based on Level III distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the SMILES code CC(=O)C1CCC(C)=CCCC=C(C)CCC1=C as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (86.3%) and water (9.5%) with small amounts to sediment (4.2%) and air (<0.1%).

The SimpleTreat model, which is incorporated in EUSES simulates the distribution of the substance in a Sewage Treatment Plant based on vapour pressure, water solubility, log Koc and ready biodegradability. Model calculations show that 0% of the substance will be degraded, and that 39.28 %, 42.16%, 17.12% and 1.44% will partition to water, primary settler, surplus sludge and air, respectively.
