The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Disulfiram is considered as not readily biodegradable

Key value for chemical safety assessment

Additional information

One study according to the OECD Guideline No. 301 B and GLP is available for disulfiram that investigates the ready biodegradability of the substance. The substance did not completely reach 60% biodegradation after the prolonged period of 60 d (58% after 60 d) and is therefore considered as not readily biodegradable. However, a plateau of biodegradation was not reached at the study period and it is therefore assumed that there is further potential for mineralization in the environment. The substance was not inhibitory to microorganisms, as shown by the toxicity control.
