Description of key information

In a flow-through system for 2-mercaptobenzothiazole (MBT) a BCF of < 0.8 (0.1 mg/L) - < 8 (0.01 mg/L) was determined on Cyprinus carpio within 6 weeks (MITI 1992), and hence MBT is not bioaccumulative. The described metabolites from MBT are also non-bioaccumulative (BCF<100) (EU-risk assessment, 2008).

Key value for chemical safety assessment

Additional information

The MITI-test was the only available test which reported a BCF-value (MITI 1992). Another test from Hashimoto (1978) reported that fish which were fed with benzothiazole-2-thiol showed 100 % excretion of 2-mercaptobenzothiazol after 72 hours.
