Description of key information
Acute toxicity of isononyl benzoate to earthworms:
LC50 (14d) > 1000 mg/kg soil dw
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil macroorganisms:
- 1 000 mg/kg soil dw
Additional information
The acute effects of Isononyl benzoate on earthworm Eisenia fetida fetida Savigny were determined according to the OECD guideline 207 with the nominal concentrations of 100 - 180 - 320 - 560 - 1000 mg/kg soil dry weight (DW) over a test period of 14 days. 40 test organisms with a individual weight between 0.3 - 0.6 g, divided into four replicates, were tested per concentration, solvent control and control in artificial soil as described by the guideline. For statistical evaluation, the replicates of control and solvent control were pooled.
No mortality was observed up to and including the test item concentration 1000 mg/kg soil dw. The concentration with no observed effect (NOEC) of the test item with respect to loss of body weight and sublethal symptoms was found to be 560 mg/kg soil dw after 14 days of exposure. A summary of all effects in the tested concetrations is given in the table. The validity criteria of the test guideline were fullfilled.
LC50 (14d) > 1000 mg/kg soil dw
NOEC (14d) bodyweight = 560 mg/kg soil bw.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
