Description of key information

The estimated bioconcentration factor (BCF) for Thiosemicarbazide, is 3.162 L/kg, that does not exceed the bioconcentration threshold of 2000. Thus it is concluded that Thiosemicarbazide,is not expected to bioaccumulate in the food chain.

Key value for chemical safety assessment

BCF (aquatic species):
3.162 L/kg ww

Additional information

The estimated bioconcentration factor (BCF) for Thiosemicarbazide, is 3.162 L/kg, that does not exceed the bioconcentration threshold of 2000. Thus it is concluded that Thiosemicarbazide,is not expected to bioaccumulate in the food chain.

In the supporting study, BCF factor was found to be < 3.8 - 4.2 at concentration of 0.4mg/L and <39 L/kg at concentration 0.04 mg/L in Cyprinus carpio during a 6 week exposure.
