ENVIRONMENT
The environmental effects of this compound have not been studied. Boric oxide will hydrolyse slowly in aqueous solution to form boric acid. This chemical has a low potential to effect aquatic organisms but may have a moderate potential to cause effects on secondary waste treatment plants. A moderate quantity of boric oxide released into the environment is not expected to have a significant adverse impact.
