Description of key information

Half-life in water = 0.49 day at 22°C for the THPC Urea Amine in activated slugde simulation test.

Key value for chemical safety assessment

Half-life in freshwater:
0.49 d
at the temperature of:
22 °C

Additional information

From the calculations, based on total radioactivity or calculated from the mineralisation rates, Proban STi (or its equivalent radioactivity) shows a half life of 0,49 days. Apparent Kd was calculated as 2333,33 ml g-1.
