Description of key information

The substance is acutely harmful to aquatic organisms.

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.

Additional information

Fish

With high probability acutely not harmful to fish (O. mykiss; 96 -h LC50 = 735 mg/L, meas.; Geiger et al., 1986)

No long-term results are available (no information requirement for this tonnage band).

Aquatic invertebrates

Acutely harmful to aquatic invertebrate (D. magna; 48 -h EC50 = 87.85 mg/L, nom.; KBWS, 1995)

No long-term results are available (no information requirement for this tonnage band).

Algae

With high probability acutely not harmful to algae (D. subspicatus, 72 -h ErC50 = 418 mg/L, nom.; KBWS, 1995)

Long-term effects are not expected (D. subspicatus; 72 -h EbC10 = 172 mg/L, nom.; KBWS, 1995)

Microorganisms

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations (P. putida; 17 -h EC50 > 4000 to < 8000 mg/L, nom.; KBWS, 1995).
