Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
Description of key information
Saccharin is significantly removed from WWTPs (90% removal efficiency) in US. Similar WWTP-results have been reported both from Germany and China. The removal frequency were high both in the sludge- and water face of the WWTP process.
Key value for chemical safety assessment
- Half-life in freshwater:
- 15 d
- at the temperature of:
- 25 °C
- Half-life in freshwater sediment:
- 7 d
- at the temperature of:
- 25 °C

By applying weight of evidence approach to the target chemical 1,2-benzisothiazol-3(2H)-one 1,1-dioxide it was found that the degradation percentage of 1,2-benzisothiazol-3(2H)-one 1,1-dioxide in water and sediment medium in the range 50 to 90%.This result in ready biodegradability of the chemical.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
