Description of key information

No soil microorganisms toxicity studies were available for the test substance.

Key value for chemical safety assessment

Additional information

The supported uses for this test substance are for industrial applications with no direct application to the terrestrial compartment. Indirect exposure to the terrestrial compartment via volatilization and redeposition would be negligible based on physical/chemical parameters and fugacity modeling. Fugacity modeling in STP suggests that the fraction of the emission directed to water, sludge, and air is 28.5%, 67.2% and 4.3%, respectively. In addition, this substance has been shown to undergo some degradation under test conditions that are less than optimal for biodegradation. Thus, based on the assumption of no direct application to soil and the physical/chemical characteristics of this substance it is anticipated that exposure to the terrestrial compartment would be negligible. Furthermore, using a PNECsoil calculated via the equilibrium partitioning method, the PEC/PNECsoil ratio for this substance is substantially <1. Therefore, soil microorganisms toxicity testing for this substance is waived.
