Description of key information

A 7-day chronic NOEC value of 3.4 mg/L for Ceriodaphnia dubia (US EPA Test Method 1002.0 - Survival & Reproduction) exposed to neodecanoic acid.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
3.4 mg/L

Additional information

Experimental long-term toxicity data for the registered substance are adequate for the purpose of classification and labelling and/or risk assessment. Supporting information is provided by chronic aquatic toxicity values calculated using the neutral organics-acid structure-activity relationship in the ECOSAR computer program (Nabholz and Mayo-Bean, 2009) of EPISuite; the results of which are consistent with the measured test data. The experimental NOEC of 3.4 mg/L is also consistent with data for a similar material, Neoheptanoic acid which produced a 21-Day NOEC of 4.8 mg/L for Daphnia magna.
