Key value for chemical safety assessment

Additional information

Based on the results of a test, which was conducted according to the Guideline EG C.1 and GLP, the 96-hour LC50 of 2,3-bis((2-mercaptoethyl)thio)-1-propanethiol for rainbow trout (Oncorhynchus mykiss) was determined to be 0.21 mg/L. The no observed effect concentration (NOEC) was determined to be 0.01 mg/L. Thus, 2,3-bis((2-mercaptoethyl)thio)-1-propanethiol can be considered as very toxic to fish.
