Description of key information
Additional information
- The 96 h LC50 (Danio rerio; mortality); > 500 mg/l and the 96 h NOEC; 500 mg/l (method 84/449/EWG, C.1; OECD 203; 1984)
- The 48 h EC50 (immobilisation) to invertebrates; 750 mg/l and the 48 h NOEC; 100 mg/l (method 84/449/EWG, C.2)
- The 72 h EC50 (Desmodesmus subspicatus; growth rate) at its maximum solubility (90 mg/l) did not cause inhibition - toxic effects, but there was observed the opposite effect – a stimulation of growth. No effective – inhibition concentrations could be calculated (OECD 201). EC50 value > 90 mg/l.
- The 3h activated sludge respiration inhibition at 24.5 mg/l concentration; 7.63 % (OECD 209)
