Description of key information
Additional information
Short term toxicity
Reliable acute toxicity tests results are available for freshwater fish (Leuciscus idus and Pimephales promelas), invertebrates (Daphnia magna) and algae (Scenedesmus quadricauda). LC50 values for the fish were between >100 and 1000 mg/L, while the EC50 for invertebrates was 1535 mg/L. A TT of 640 mg/L was determined in the algal test from which a NOEC of 425 mg/L was derived.
In accordance with Column 2 of REACH Annex VIII, the activated sludge respiration inhibition study (required in Section 9.1.4) does not need to be conducted as the substance is readily biodegradable and the applied test concentrations are in the range that can be expected in the influent to a sewage treatment plant.
Long term toxicity
In accordance with Column 2 of REACH Annex IX, the long-term aquatic toxicity to fish study (required in Section 9.1.6) and the long-term aquatic toxicity to invertebrate study (required in Section 9.1.5) do not need to be conducted as the chemical safety assessment indicates that they are not necessary:
- citric acid is an essential element in the metabolic pathway of all living organisms;
- low short-term toxicity has been reported;
- the substance is readily biodegradable, has low potential for bioaccumulation (Log Kow <3) and is soluble in water.
See IUCLID Sections 6.1.2 and 6.1.4 for further details.
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.
