Description of key information

EC50 (48h) invertebrate Daphnia: >100 mg/L

EC50 (7d) aquatic plants Lemna minor: 134 mg/L (frond number, growth rate)

NOEC (7d) aquatic plants Lemna minor: 14.9 mg/L (frond number, dry weight)

Additional information

Invertebrate acute toxicity

The median effect concentration (EC50) and the no-effect concentration (NOEC) of the substance to Daphnia magna were investigated under static exposure conditions over a period of 48 h, following the guideline OECD 202 and EU C.2.

The EC50 Daphnia magna at 24h and 48 h was found to be > 100 mg/L, based on the measured concentrations of the active ingredient.

Aquatic Plants toxicity

The inhibitory effects of the substance to the duckweed Lemna minor were investigated over a period of 7 days, based on the frond number and biomass (dry weight), following the guideline OECD 221 and the EU C.26.

The 7 day ErC50(based on frond number) on the duckweed Lemna minor is 134 mg/L, based on the measured concentrations of the active ingredient. The validity criterion was fulfilled.

The NOEC (7d) aquatic plants Lemna minor was found to be 14.9 mg/L (frond number, dry weight)
