Description of key information
Short-term EC50 values for Adenosine-5’-monophosphate (AMP) (CAS no. 61-19-8) are available for two trophic levels of the aquatic freshwater compartment (aquatic invertebrates, aquatic algae).
The acute toxicity of Adenosine-5’-monophosphate (AMP) (CAS no. 61-19-8) to the green alga Desmodesmus subspicatus was determined in a 72 hour static test according to OECD guideline 201. The median effect concentrations (EC50) of Adenosine-5’-monophosphate on the green alga Desmodesmus subspicatus were estimated to be >100 mg/l nominal concentration after 72 h of exposure. The NOEC values were determined to be 100 mg/l nominal concentration after 72 h of exposure. The results of the test can be considered reliable without restriction.
The acute toxicity of Adenosine-5’-monophosphate (AMP) (CAS no. 61-19-8) to Daphnia magna was determined in a 48 hour static test according to OECD guideline 202. The median effect concentrations (EC50) of Adenosine-5’-monophosphate on Daphnia magna were estimated to be >93.4 mg/l and >81.6 mg/l measured concentration after 24 h and 48 h of exposure, respectively. The NOEC values were determined to be 93.4 mg/l and 81.6 mg/l measured concentration after 24 h and 48 h of exposure, respectively. The results of the test can be considered reliable without restriction.
Conclusion on classification
The environmental classification of Adenosine-5’-monophosphate (AMP) (CAS no. 61-19-8) is currently not harmonised according to the CLP Regulation (EC) 1272/2008. Based on available acute aquatic toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is >81.6 mg/L (EC50 48 h for aquatic invertebrates). Based on the available acute data, the substance should not be classified for acute toxicity following Annex I, table 4.1.0a of the CLP regulation (there are no acute values <=1 mg/L).
Additional information
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.
