Description of key information

Expert Judgement
If released to soil, Dipotassium oxide/Potassium oxide is expected to have very high mobility based upon an estimated Koc of 13.22. Volatilization from moist soil surfaces is not expected to be an important fate process.

Therefore testing for biodegradation in soil does not need to be performed.

Key value for chemical safety assessment
