Additional information

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

Anhydrous: 194 to 5928 mg/L,

Octahydrate: 231 to 7075 mg/L.

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