Description of key information

Three independent O.E.C.D. test guideline 203 studies were conducted with the test substance, 2,3-epoxypropyl o-tolyl ether.  

Key value for chemical safety assessment

Fresh water fish

Fresh water fish
Effect concentration:
2.8 mg/L

Additional information

Two independent O.E.C.D. test guideline 203, GLP studies were conducted with the rainbow trout with concentration verification. Based on measured concentrations the LC50 value from these two studies ranged from 2.8 - < 10 mg/L A third supporting O.E.C.D. test guideline 203 study was performed with the Zebra-Fish. Based upon estimated concentations of the test substance, the LC50 valued ranged from 5.5 - 8.0 mg/L (95% Confidence Limits). Therefore, the test substance, 2,3 -epoxypropylo-tolyl ether, is toxic to fish under the conditions of the studies.
