Description of key information

The 21 day NOEC of  C6 Pyrazole Hemisulfate to Daphnia magna was 0.29 mg/L expressed as test material, based on mortality and growth (carapace measurements) and 0.12 mg/L expressed as test material, based on reproduction.  The results were based on time-weighted mean measured test concentrations. 

Key value for chemical safety assessment

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

Additional information

The 21-day chronic toxicity ofC6 Pyrazole Hemisulfateto Daphnia magna was determined under semi-static conditions according to the OECD Guideline 211 (Daphnia magna Reproduction Test) guideline and following the GLP. 

The 21 day NOEC of C6 Pyrazole Hemisulfateto on Daphnia magna reproduction was 0.29 mg/L expressed as test material, based on mortality and growth (carapace measurements) and 0.12 mg/L expressed as test material, based on reproduction. The results were based on time-weighted mean measured test concentrations.
