Description of key information
14-d LC50: 406.3 mg /kg soil dw (acute, earthworm, OECD 207, Friedrich, 2010)
4-wk NOEC (reproduction): 7.81 mg/kg soil dw (chronic, 8 wk test duration, earthworm, OECD 222, Friedrich, 2011)
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil macroorganisms:
- 406.3 mg/kg soil dw
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 7.81 mg/kg soil dw
Additional information
Summary of the data:
14-d LC50: 406.3 mg /kg soil dw (acute, earthworm, OECD 207, Friedrich, 2010)
4-wk EC50 (reproduction): 16.64 mg/kg soil dw (chronic, 8 wk test duration, earthworm, OECD 222, Friedrich, 2011)
4-wk NOEC (reproduction): 7.81 mg/kg soil dw (chronic, 8 wk test duration, earthworm, OECD 222, Friedrich, 2011)
Two studies are available (earthworm: one short-term & one long-term). Both are considered to be relevant, reliable, adequate for risk assessment, and adequate for classification purposes. The LC50 (acute test) and the NOEC (chronic test) results are carried forward for risk assessment purposes.
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.
