Description of key information
The EU RAR summarises the results from a number of higher plant studies which, individually, may have limitations regarding study design and reliability. However, the results of these studies when taken as a whole, provide an adequate assessment of the effects of Cr(VI) to higher plants.
Key value for chemical safety assessment
Additional information
From the EU RAR, a review of the effects of a range of Cr(VI) and Cr(III) substances was carried out. A range of plants species, endpoints, exposure durations and study designs were used to provide a reasonable assessment of toxicological hazard. The lowest NOEC was 0.35 mg Cr(VI)/kg dry weight soil.
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.
