Description of key information
A study was performed in accordance with OECD guideline 207 and in compliance with GLP. The 14-d LC50 of Mo2C to earthworms (Eisenia fetida) was higher than 1000 mg/kg dry soil.
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil macroorganisms:
- 1 000 mg/kg soil dw
Additional information
A study was performed in accordance with OECD guideline 207 and in compliance with GLP to identify the toxic effects of dimolybdenum carbide (Mo2C) on soil macroorganisms. Based on the result of a preliminary test, the definitive study was conducted as limit test with the concentrations 0 and 1000 mg Mo2C per kg dry soil. During the test period, neither mortality nor any toxic symptoms (weight loss, behavioural and pathological effects) were observed in both the control group and in presence of Mo2C. Accordingly, the 14-day LC50 of Mo2C to earthworms (Eisenia fetida) is higher than 1000 mg/kg dry soil.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
