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.
