Abiotic degradation


Based on estimation with the QSAR model Aopwin the substance undergoes in air rapid degradation after reaction with hydroxyl radicals or ozone. The DT50 values after reaction with hydroxyl radicals is 3.3 hours The DT50 values after reaction with ozone could not be calculated. The estimated half-life time is much shorter than 2 days, which is the cut off time for reaching the stratosphere. The substance is therefore not expected to reach the stratosphere and is not a long-range transported chemical in air according to the UNECE criteria (http: //www. unece. org/fileadmin/DAM/env/documents/2000/ece/eb/ece%20eb%20air.60. e. pdf).

In addition, the substance does not have an ozone depletion potential, because it does not contain halogens (CLP, 2014, Part 5 (page 203),

Water: Some hydrolysis may be expected because the substance is an ester. Based on experience with similar substances these esters are stable at pH 7 and therefore the half-life time at 25°C is >1 year.

Biotic degradation

In a screening study according to OECD TG 301F, 71% biodegradation was found after 28 days (76% biodegradation after 32 days) and is considered to be readily biodegradable in view of the pass level > 70% and the substance being a multi-constituent.


The log Kow of 3.2 is used as an indicator for the bioaccumulation potential. Based on this result the substance has a limited bioaccumulation potential with an estimate BCF value of 105 L/kg for aquatic organisms. The bioaccumulation potential of Verdox an analogue of Jasmal will be used for the risk assessment: 156 based on 5% lipid. The calculated BCF of 19.9 L/kg will be used for terrestrial organisms (EUSES equation).

Transport and distribution

The adsorption coefficient (Koc) of the substance has been determined to be in the range 240 -760 L/kg, log Koc of 2.37 -2.88, using the HPLC screening method (OECD 121). This indicates that the substance will have low potential to adsorb to sediment/soil. The lower value will be used for the risk assessment because this is anticipated to be related to the main trans-isomer.

To assess the volatilisation potential of the substance a Henry's law constant was calculated which gave a result of 0.52 Pa. m³/mol at 25oC and 0.25 at 12oC. From the distribution modelling results it can be concluded that volatilisation is of minor importance in the environmental behaviour of the substance. 

Based on Level III distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 1887-14-2 and the estimated physico-chemical parameters , it is estimated that the majority of the substance released to the environment will partition into water (26.7%) and soil (72.4%) with small amounts to sediment and air (0.2% and 0.6%, respectively). 

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 Kow and (non) ready biodegradability. The model predicts that 81.5% of the substance will be biodegraded, 12% will partition to water, 6.5% will partition to sewage sludge and 0.1% to air.
