Description of key information
Additional information
Chromium(III) hydroxide is insoluble between pH 6.8 and 11.5 (see section 4.8). The main toxic principle of Chromium(III) hydroxide is dissolved Cr(III). Therefore significant terrestric toxicity is not expected in this pH range, because Cr(III) is not available. There are a number of studies available for water soluble Cr(III) salts, that cover the pH range < pH 6.8 and > pH11.5.
The 8 wk NOEC of earth worms (Eisenia fetida) was 46000 mg Chromium(III)/kg ww based on growth for the insoluble Chromium(III) oxide. The 3 wk of NOEC 34 – 280 mg Chromium(III) /kg soil dw was determined for Chromium(III) nitrate (reproduction – growth, cocoon production (Earthworms, Eisenia Andrei)
For terrestrial plants (grain species) the 5mo NOEC was 200 – 631 mg Chromium(III)/kg soil dw growth (Chromium(III) acetate).
The HC5-50% = 5.9 mg Chromium(III)/kg and HC5-95% = 2.1 mg Chromium(III)/kg of Chromium(III) chloride was calculated for microorganisms responsible for soil processes.
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.
