Description of key information

The acute toxicity of the test material to the freshwater invertebrate Daphnia magna has been investigated and resulted in a 48 hour EC50 of 1.16 mg/L and a 48 hour no observed effect concentration (NOEC) was 0.894 mg/L benzyl salicylate.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
1.16 mg/L

Additional information

The test (OECD 202) was performed under static conditions in sealed vials with no head space to minimize the potential loss of the test substance from test solutions to the atmosphere. The test was run with five concentrations of test substance at a temperature of 20 ± 1°C. Mean measured concentrations of benzyl salicylate were: ND (none detected at or above the limit of quantitation of 0.00223 mg/L; control), 0.894, 1.64, 2.47, 4.02, and 6.23 mg/L. These mean measured concentrations, which ranged from 78 to 91% of nominal concentrations, were steady throughout the exposure period. Exposure of daphnids to benzyl salicylate resulted in a 48 hour median effective concentration (EC50) of 1.16 mg/L (95% confidence interval = 0.894 to 1.64 mg/L) and a 48 hour median lethal concentration (LC50) of 2.25 mg/L (95% confidence interval = 1.64 to 4.02 mg/L). The 48 hour no observed effect concentration (NOEC) was 0.894 mg/L benzyl salicylate.
