Description of key information
The ready biodegradation of propene has been estimated using the BioWin models according to the criteria set out in the ECHA Information Requirements R.7b. The QSARs for Propene meet all the screening criteria to be able to be classified as "Readily Biodegradable". Propene has therefore been classified as readily biodegradable. The BioHCwin model was used to calculate the substance half-life which was determined to be 2.36 days.
There are experimental data available for the ready biodegradation of propene which show it as not Readily Biodegradable. However, these data may not be appropriate for classification due to the specific properties of the substance. The substance is a gas at room temperature and pressure and undergoes half-life photolysis within 15 hours of being in the atmosphere.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Propene would not be considered readily biodegradable (MITI 2001). However, various researchers have demonstrated that microorganisms which can biodegrade propene have been isolated from soil samples (e.g. van Agteren et al 1998).
A substance may be considered persistent (likely to meet the screening criteria for P) if the QSAR calculations show a Biowin 3 value <2.2 and Biowin 2 or 6 values < 0.5. For propene, Biowin 3 predictions an ultimate degradation time of 3.1 (degradation in weeks) and Biowin 2 and 6 predict fast biodegradation probabilities of 0.92 and 0.80, respectively. The BioHCwin QSAR (v1.01, particularly applicable to petroleum hydrocarbons) predicts a propene half life of just 2.36 days. Based on these data, propene will not persist in the environment and so does not meet the screening criteria for P designation.
As propene is a gas at atmospheric conditions a standard ready biodegradability test is technically difficult and, based on exposure estimates, the test may not be relevant. EPIWIN predicts rapid volatilisation from water (half life of 40 minutes in a river, 2.6 days in a lake). Degradation of propene is also expected to be rapid once in the atmosphere. According to Atkinson (1985), the photodegradation half-life for propene is 14.6 hours in the atmosphere based on a range of experimental results for rate constants and the concentration of hydroxyl radicals recommended in the Technical Guidance Document (2003).
