Description of key information

In a reliable OECD guideline and GLP compliant study, the 48 h EC50 and NOEC of C16-C18 TMAC were 0.0091 and 0.0026 mg a.i./L, respectively.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0.009 mg/L

Additional information

An OECD guideline study was conducted to evaluate the acute toxicity of Dapnia magna exposed to C16 -C18 TMAC under static conditions.

Daphnia magna (10 per dose) were exposed to the test substance at nominal concentrations of 0.0010, 0.0018, 0.0032, 0.0056, 0.010, 0.018, 0.032, 0.056 and 0.10 mg/L for 48 hours and immobilisation was determined.The 48 -hour EC50 and 95% confidence interval were calculated as 0.0091 and 0.0072 -0.012 mg a.i./L. The 48-hour NOEC was 0.0026 mg a.i./L. No analytical determination was performed for the test substance.Under the test conditions, the 48 -hour EC50 and NOEC were 0.0091 and 0.0026 mg a.i./L, respectively (Handley JW and Wetton PM, 1990).
