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

Additional information

ZMBT is an organic complex, in which MBT structure is present. The dissolution of MBT determines the hazard profile of ZMBT aqueous solution; and hence the environmental fate and behavior of MBT is used as read-across approach to support the risk assessment of ZMBT. In a flow-through system with the species Cyprinus carpio a BCF of <0.8 at a concentration of 0.1 mg/l and <8 at a concentration of 0.01 mg/l was determined for MBT; and hence MBT is not bioaccumulative.
