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 22.1 mg/m3. However, several plant species have been tested which show little or no effects when exposed to 100 times this concentration.
