Description of key information
According to the SRC PhysProp Database the estimated log Pow for ozone is –0.87.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -0.87
- at the temperature of:
- 20 °C
Additional information
Additionally, ozone is an unstable, highly reactive (oxidising) inorganic gas and has therefore no bioaccumulation potential.
