Description of key information
Half life period of chlorocresol in water was observed to be 38 days while in sediment it is 340 days. Based on these half life values of it is concluded that chlorocresol is readily biodegradable in water where as it is non biodegradable in sediment. However, since there is no diffusion of the substance in the sediment as evident from the reported data (1% in sediment) and hence persistence in the sediment compartment is not likely to be critical.
Key value for chemical safety assessment
- Half-life in freshwater:
- 37.5 d
- at the temperature of:
- 25 °C
- Half-life in freshwater sediment:
- 337.5 d
- at the temperature of:
- 25 °C
Additional information
Based on level III fugacity model the half life period of chlorocresol was estimated
