Conclusion on classification

The results from the aquatic toxicity studies are as follows:

LC50 (96 h) fish = 12.7 mg/l (measured concentration) with 95% confidence limits of 8 -16 mg/l.

EC50 (48 h) Daphnia = 22.1 mg/l (measured concentration) with 95% confidence limits of 18.4 - 24.3 mg/l.

ErC50 (72 h) algae = 80.6 mg/l (measured concentration) with 95% confidence limits of 78.9-82.3 mg/l.

EC50 microorganisms was determined to be greater than 1000 mg/l.

Based on the results from the aquatic toxicity (values in the range 10 -100 mg/l) and since the substance is not readily biodegradable and has a log Kow of 0.87 (log Kow < 4), the substance is classified as follows:

- according to Directive 67/548/EEC the substance RDX is not classified hazardous to the aquatic environment.

- according to the CLP Regulation 1272/2008 the substance RDX is not classified hazardous to the aquatic environment.
