Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
In a short-term respiration test performed by BASF (1978) the 30min EC20 for activated sludge was > 261 mg/L, corresponding to the highest tested concentration.
The study was conducted without analytical monitoring. However, it is
assumed that the test concentrations remained stable over the exposure
period based on a high water solubility (miscible at any ratio; see
IUCLID ch. 4.8), a low vapour pressure (0.63 hPa at 25 °C, see IUCLID
ch. 4.6) a low Henry's Law constant (4.95E-05 Pa m³/mol, HENRYWIN v3.20,
BASF SE, 2017) and a low adsorption potential (log Kow = -0.93, BASF AG,
1987; log Koc = 1.53, according to Franco&Trapp, BASF SE, 2021). The
stability over the exposure period was additionally confirmed by an
available acute toxicity study on fish conducted with analytical
monitoring and a recovery rate of 96% (Brooke, 1984).
