Description of key information

Half-life period of Thiosemicarbazide, in water is observed to be 15 days (360 hrs.) while in sediment it is 135 days (3240 hrs). Based on these half-life values of Thiosemicarbazide, it is concluded that the chemical is not persistent in water and sediment

Key value for chemical safety assessment

Half-life in freshwater:
15 d
at the temperature of:
25 °C
Half-life in freshwater sediment:
135 d
at the temperature of:
25 °C
