Additional information
No experimental data is available regarding aquatic toxicity of Sodium-2-formylbenzenesulphonate.
The substance should be of low concern for aquatic toxicity based of predicted values by ECOSAR v. 1.11. Note: The ECOSAR class used for the prediction was Aldehydes (mono-acid). Sodium-2 formylbenzenesulphonate was entered in ECOSAR as the neutral non-salt form. As reported in the Help of ECOSAR regarding the model on salt form : " The properties and toxicity of a small number of organic salts are well documented in the environmental literature such as Sodium (Na) salts, Potassium (K) salts, Ammonium (NH4+) salts, and Lithium (Li) salts. Simple salts can be entered into the system and modelled by neutralizing the compounds (remove the salt, replace with a hydrogen atom) as the salts are typically treated as spectator ions". The predicted data reported in this summary are based on this assumption. Regarding Daphnid data the model gave an alert for chemical that should be no soluble enough to predict this value. This alert is not valid for Sodium-2-formylbenzenesulphonate (predicted solubility in water 1,000,000 mg/l- see section 4.8 of this IUCLID dossier).
Acute toxicity:
Predicted value by ECOSAR v.1.11 for Sodium-2-formylbenzenesulphonate are:
LC50 96h fish = 65139.750 mg/l
LC50 48h Daphnid = 1.43*10^6 mg/l
EC50 96h green algae = 6.66*10^5 mg/l
Chronic toxicity:
There is no study available for chronic toxicity to aquatic environment of Sodium-2-formylbenzenesulphonate but no particular alert is expected as the substance is predicted ready-biodegradable and it is used as intermediate under strictly controlled conditions with no aquatic environmental exposure.
Based on predicted data for acute aquatic toxicity and considering that the substance is used as intermediate under strictly controlled conditions with no aquatic environmental exposure, no classification is proposed for aquatic toxicity for Sodium-2-formylbenzenesulphonate according to the CLP Regulation (EC n. 1272/2008).
Conclusion on classification
Based on predicted data for acute aquatic toxicity and considering that the substance is used as intermediate under strictly controlled conditions with no aquatic environmental exposure, no classification is proposed for aquatic toxicity for Sodium-2-formylbenzenesulphonate according to the CLP Regulation (EC n. 1272/2008).
