Additional information

The substance was found to be not toxic for aquatic organisms EC50 > 100 mg/L: .

LC50 (48h) = > 100 mg/L for Daphnia magna; value based nominal concentration

. The NOEC after 48 h was determined at 100 mg/L. The LOEC after 48 h was >100 mg/L (all values based on nominal concentration).

Acute toxicity to Desmodesmus subspicatus 72h (OECD 201): The ErC50 was calculated at > 354 mg test substance/L after 72 h of testing. This value is above the water solubility of the substance. The EyC50 (yield) was calculated to be > 211mg test substance/L (CI: 200 - 224). The NOEC (72h) is 177 mg/L (rate related inhibition) and the LOEC (72h) is calculated at 254 mg/L (rate related inhibition) (all values based on the geometric mean). The NOEC (72h) is 117 mg/L (Inhibition of yield) and the LOEC (72h) is calculated at 177 mg/L ( Inhibition of yield) (all values based on the geometric mean).
