Conclusion on classification

The environmental classification of NMMO is currently not harmonized according to the CLP Regulation (EC) 1272/2008 and the Dangerous Substances Directive 67/548/EC.

Based on available acute aquatic toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is > 100 mg/L. One chronic datapoint is available, a 72h-NOErC for algae > 100 mg/L but this value is not used for the PNEC derivation. Based on these results and although the test substance is not readily biodegradable, it should not be classified for acute or chronic toxicity for the aquatic environment according to Annex 1 (section 4.1.2.6) of the CLP Regulation. Based on the same criteria the substance should not be classified for the environment under the Dangerous Substances Directive 67/548/EC (see Annex VI section 5.2.1.2).
