Additional information

Based on the aquatic toxicity data, the test substance is not classified as hazardous to the environment in accordance with Regulation (EC) No 1272/2008

Conclusion on classification

The following acute toxicity studies were performed at the limit of solubility of HMX (4.46 mg/L at 25C in pure water)

96 hr LC 50 (for fish) > 15 mg/l (nominal concentration)

48 hr EC 50 (for daphnia) > 15 mg/l (nominal concentration)

96 hr ErC 50 (for algae) > 6.5 mg/l (measured concentration)

Therefore HMX is not classified as an acute aquatic hazard to the aquatic environment in accordance with Regulation (EC) No 1272/2008

32 d NOEC (for fish) > 3.3 mg/l (measured concentration)

28 d NOEC (for Daphnia) >3.9 mg/l (measured concentration)

96 hr ErC 50 (for algae) > 6.5 mg/l (measured concentration) and the substance is not rapidly degradable and its log Kow<4

Therefore HMX is not classified as a long term hazardous substance to the aquatic environment in accordance with Regulation (EC) No 1272/2008
