Description of key information
In the same study, survival and growth of Chironomus tentans and Hyalella azteca were assessed when exposed to HMX. Survival of the Chironomus tentans was unaffected after exposure to the test substance at the highest concentration of 400 mg/kg. Significantly increased growth was observed after exposure to sublethal concentrations of the test substance. The 10d NOEC of the test substance is > 145.8 mg/kg sediment dw. Survival of the Hyalella azteca was unaffected after exposure to the test substance at the highest concentration of 400 mg/kg. Significantly increased growth was observed after exposure to sublethal concentrations of the test substance. The 10d NOEC of the test substance is > 126 mg/kg sediment dw
Key value for chemical safety assessment
- EC10, LC10 or NOEC for freshwater sediment:
- 145.8 mg/kg sediment dw
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.
