Additional information

The test substance, 2,3 -epoxypropyl o-tolyl ether has an EC50/LC50 value of 2.8 mg/L and is not readily biodegradable. Therefore, the test substance is hazardous to the environment.

Conclusion on classification

The test substance,2,3 -epoxypropylo-tolyl ether, has a measured EC50/LC50 value of 2.8 mg/L for both fish (rainbow trout) and Daphnia. Therefore, the test substance is considered Toxic to aquatic organisms. Furthermore, since the test substance is not readily biodegradable, it may cause long-term adverse effects on aquatic life.
