Description of key information
Acutely toxic to aquatic algae.
Key value for chemical safety assessment
Additional information
(2-hydroxyethyl)ammonium nitrate is soluble in water and dissociates to (2 -hydroxyethyl)ammonium and nitrate.
Since no studies on the aquatic toxicity of the substance (2 -hydroxyethyl)ammonium nitrate are available, study reports and published literature about the toxic effects of its dissociation products have been consulted alternatively.There are two studies available on the toxicity of 2 -aminoethanol (CAS 141-43-5) to aquatic algae (Scenedesmus subspicatus and Selenastrum capricornutum) with EC50 values from 2.8 - 22 mg/L (growth rate). Corresponding NOECs were determined to be in the range of 1 to 4 mg/L.
Based on a reliable guideline study with potassium nitrate (CAS 7757-79-1), it was shown that the substance was not at all or only slightly inhibitory at the highest concentration tested. After an exposure period of 10 days, an EC50 of 1043 mg/L nitrate was derived from testing with 10 different cultures of benthic diatoms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
