Description of key information

Studies on the toxicity to terrestrial plants are not available for sodium dichromate. The substance sodium dichromate consists of sodium cations and dichromate anions (Cr2O7-). Based on the solubility of sodium dichromate in water, a complete dissociation resulting in sodium cations and chromate anions may be assumed under environmental conditions. Therefore, the fate and toxicity of sodium dichromate in the environment is most accurately evaluated by assessing the fate and toxicity of its ecotoxicologically relevant moiety, i.e. the chromate anion, and read-across to data available for other (soluble) chromate substances is applied.

 

Please refer to the respective endpoint summary for soluble chromium (VI) substances for further information.
