Description of key information

Short-term toxicity to fish:

OECD Guideline 203 (Fish, Acute Toxicity Test) 96h Rice fish - LC50 14.1 mg/L

OECD Guideline 203 (Fish, Acute Toxicity Test) 96h Rare Minnow fish - LC50: 1.78 mg/L (key study)

Long-term toxicity to fish: OECD Guideline 210 (Fish, Early-Life Stage Toxicity Test) (Key study)

NOEC (length & weight) = 1.25% stock solution (measured concentration 0.131 mg/L);

LOEC (length & weight) = 2.5% stock solution (measured concentration 0.426 mg/L).

Short-term toxicity to aquatic invertebrates: OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)

48h Daphnia magna EC50 = 92.9 mg/L

Long-term toxicity to aquatic invertebrates: OECD Guideline 211 (Daphnia magna Reproduction Test)

Under valid semi-static test conditions (72h-renewal), for Daphnia magna reproduction the LOEC was 0.322 mg/L (measured TWA concentration) and the NOEC was 0.261 mg/L (measured TWA concentration). For survival of adults, the LOEC was 0.261 mg/L (measured TWA concentration), the NOEC was 0.186 mg/L (measured TWA concentration).

Toxicity to algae: OECD Guideline 201 (Alga, Growth Inhibition Test)

72-hour ErC50 = > 14.4 mg/L

NOECr = 4.24 mg/L

Toxicity to microorganisms: OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test

30-minute EC50: >862 mg/L (analytical).
