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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hazard for predators
Secondary poisoning
- Hazard assessment conclusion:
- no potential for bioaccumulation
Additional information
From a fugacity model (McKay Level III) based on key physical and chemical property parameters, it can be concluded that the ultimate compartment is the aquatic compartment. PnB is readily biodegradable and has no potential for bioaccumulation. Direct and indirect exposure to the soil compartment is unlikely. Secondary poisoning is therefore not considered as relevant route of exposure for consumers and workers.
Conclusion on classification
According to Chapter 4 VI of Directive 67/548/EEC, no classification is required, as all EC50>100mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
