Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 accordance with column 2 of REACH Annex IX and X, toxicity testing on plants does not need to be conducted as direct and indirect exposure of the soil compartment is unlikely and the the chemical safety assessment according to Annex I has not indicated a need to investigate further the effects of the substance and/or degradation products on terrestrial organisms.
Key value for chemical safety assessment
Additional information
Although an adaptation can be used to waive this study some data are available from studies that have exposed plants to 1,3-butadiene via air. These non-standard studies have tested the toxicity of 1,3-butadiene to several species of plants. Low toxicity is generally shown. The lowest concentration reported to show no effects over a 21-day exposure period was 22.2 mg/m3. However, several plant species have been tested which show little or no effects when exposed to 100 times this concentration.
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.
