Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Sediment toxicity testing of 4-vinylpyridine (4VP) was waived. According to Regulation (EC) No.1907/2006, Annexes IX and X, Column 2, these studies need not be conducted unless the Chemical Safety Assessment indicates the need to investigate further the degradation of the substance or its degradation products. According to Annex I, if the risk characterisation ratio in the chemical safety assessment is below 1.0, the risks are considered controlled. In the chemical safety assessment of this substance, the risk characterization ratio is below 1. The calculated PNECs for sediment organisms were derived on the basis of equilibrium partitioning, and are in the same range or higher as for freshwater organisms, and so toxicity testing of sediment organisms is not specifically indicated. Therefore, the criteria are met and there is no need to require additional testing in this area.

Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
