Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Additional information

In a GLP guideline study conducted according to OECD 121 Henke & Paulus (2008) estimated the adsorption coefficient of acetic acid, chromium salt, basic on soil and sewage sludge using a HPLC method. The calculated log Koc is <1.5.

Further information on chromium is available from the EU Risk Assessment Report (2005). Chromium (VI) anions can be considered to be mobile in sediments in the environment, except possibly under highly acidic conditions. In contrast chromium (III), the oxidation state in which chromium is prensent in acetic acid, chromium salt, basic, appears to be much more strongly adsorbed to soils and sediments than chromium (VI). The adsorption of chromium (III) onto soil follows the pattern typical of cationic metals and increases with increasing pH (lowering pH results in increased protonation of the adsorbent leading to fewer adsorption sites for the cationic metal) and the organic matter content of the soil and decreases when other competing (metal) cations are present. Certain dissolved organic ligands may also reduce the adsorption of chromium (III) to the solid phase by forming complexes which enhance the solubility of chromium (III) in the aqueous phase.
