Description of key information
The acute toxicity of Amyl Salicylate to the earthworm Eisenia fetida in artificial soil has been determined. The LC50 is regarded to be 127.8 mg test item/kg soil (dw).
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil macroorganisms:
- 127.8 mg/kg soil dw
Additional information
The acute toxicity of the test item to earthworm Eisenia fetida in artificial soil test has been investigated and gave a 14 day LC50 value of 127.8 mg test item/kg soil dry weight (dw).
Fisher’s Exact Test (1-sided, p ≤ 0.05) showed significant differences concerning mortality between the solvent control and all test item concentrations tested. Therefore, the NOECMortality could not be determined and was regarded as < 100 mg test item/kg soil (dw). The LOECMortality was considered to be ≤ 100 mg test item/kg soil (dw).
No mortality was observed in the control. In the solvent control 5% mortality (validity criterion ≤ 10%) was observed and at the concentrations of 100, 178, 316, 562 and 1000 mg test item/kg artificial soil dw (dry weight) 37.5%, 72.5%, 75.0%, 92.5% and 100% mortality was observed, respectively.
The percent of the initial weight of the earthworm biomass after 14 days was 103.7% for the control, 100.5% for the solvent control and 100.8% to 105.2% for all concentrations of the test item tested where survived earthworms were found, respectively.
There were no effects on behaviour or morphology of the earthworms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
