Description of key information

Short term effects on fish ranged from 74 to 725 mg B/L. Equivalent concentrations of dipotassium tetraborate would be:


Anhydrous: 400 to 3919 mg/L,


Tetrahydrate: 523 to 5124 mg/L.


Short term effects on aquatic invertebrates ranged from 45 to 1376 mg B/L. Equivalent concentrations of dipotassium tetraborate would be:


Anhydrous: 243 to 7438 mg/L,


Tetrahydrate: 318 to 9724 mg/L.


Short term effects on the algae Pseudokirchneriella subcapitata (formerly Selenastrum capricorntum) were observed at 40 mg B/L.


Equivalent concentrations of dipotassium tetraborate would be:


Anhydrous: 216 mg/L,


Tetrahydrate: 283 mg/L.


These data support a conclusion that borates should not be classified as dangerous for the environment.
