Description of key information

The EC50 of 2,3-bis((2-mercaptoethyl)thio)-1-propanethiol for Algae is 1.5 mg/L, which indicate that the substance is toxic to Algae. 

Key value for chemical safety assessment

EC50 for freshwater algae:
1.5 mg/L

Additional information

Based on the results of a test, which was conducted similar to the Guideline OECD 201, the 72-hour EC50 of 2,3-bis((2-mercaptoethyl)thio)-1-propanethiol for Selenastrum capricornutum determined to be 1.5 mg/L.

The no observed effect concentration (NOEC) was determined to be 0.125 mg/L.

Thus, 2,3-bis((2-mercaptoethyl)thio)-1-propanethiol can be considered as toxic to aquatic algae.
