After stirring for 1 h all test item concentrations were
dissolved. The colours of the solutions were slightly brown (10 mg/L
stock solution and 10 mg/L), brown (32 mg/L and 100 mg/L) and colourless
to slightly yellow (320 mg/L).
One key experimental study was reported, Respiration Inhibition Test with Activated Sludge with EC50 of 29.9 mg/L.
For short-term toxicity to micro-organisms, there
is one key study conducted in 2010,
Respiration Inhibition Test with Activated Sludge according
to OECD 209 with an EC50 of 29.9 mg/L.
