Description of key information
Bioconcentration factors of 1,2-benzisothiazol-3(2H)-one 1,1-dioxide was found to be 1.58 and 2.1 based on a water solubility of 4000 mg l-1 at 25°C and Log Pow of 0.91. This suggests bioconcentration in aquatic organisms is unlikely for the chemical 1,2-benzisothiazol-3(2H)-one 1,1-dioxide.
Key value for chemical safety assessment
- BCF (aquatic species):
- 2.1 dimensionless

By applying weight of evidence approach to the target substance 1,2-benzisothiazol-3(2H)-one 1,1-dioxide,the endpoint value of bioaccumulation was found to vary between BCF = 1.58 to 6.38 in aquatic organisms /fish.Thus it is concluded that the test substance 1,2-benzisothiazol-3(2H)-one 1,1-dioxide is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria of 2000.
