Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicity to terrestrial plants
Administrative data

Description of key information
Only one study was available that evaluated toxicity of ethylbenzene to terrestrial plants. Detached leaves of the runner bean (Phaseolus
multi-florus) and parsnip (Pasticana sativa) were exposed at a range of vapour concentrations for 1 hour. This study was considered unreliable due to an unreliable test system and given a Klimisch score of 3. No other data are available for ethylbenzene exposure to terrestrial plants.
Key value for chemical safety assessment
Additional information
The concentration causing 50 % injury to the leaves of Phaseolus multiflorus (EC50) was 27 mg/L, while the concentration causing 50 % injury to the leaves of Pasticana sativa (EC50) was 48 mg/L. The test design for this study was considered unacceptable, therefore the study was given a Klimisch score of 3 and was considered unreliable. No other data are available for ethylbenzene toxicity to terrestrial plants. However, the substance is not likely to contaminant the soil compartment based on a Level II fugacity model (McKay Level I) and if released into the soil, ethylbenzene is expected to
biodegrade and has a BCF of 110.
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.
