Additional information

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

Anhydrous: 281 to 2750 mg/L,

Pentahydrate: 404 to 3957 mg/L.

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