Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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

In a flow through system, the measured BCF value was reported to be 20 to 43 and 44 to 48 in Cyprinus carpio upon an 8-week exposure to 40 µg/L and 4 µg/L of PtBP, respectively.  Based on the available data on the biotransformation of ptBP and considering the rapid elimination of phenolic compounds from mammalian or aquatic organisms, ptBP is unlikely to bioaccumulate in the food chain.

Key value for chemical safety assessment

Additional information

The bioaccumulation potential of ptBP was studied in Cyprinus carpio exposed to 40 µg/L and 4 µg/L of PtBP for 8 weeks in a flow through system. A BCF of 20-43 was achieved upon exposure to 40 µg/L of ptBP, while exposure to 4 µg/L of PtBP resulted in a BCF of 48-88 was measured.
