Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The half life period of 1,2-benzisothiazol-3(2H)-one 1,1-dioxide in water is 15 days and based on this value it can be concluded that the chemical is not persistent in water medium since the half life is less than the threshold of 60 days (to qualify the chemical as persistent).
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
No. of studies reviewed for Biodegradation in water:screening tests from reliable sources having Klimisch rating 2.

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 medium is 50 to 58%.This result in ready biodegradability of the chemical.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
