Additional information

In an activated sludge respiration inhibition test, secondary activated sludge of a predominantly domestic sewage treatment plant was exposed to dicumyl peroxide adsorbed on silica gel at a concentration 1000 mg/L (nominal) under static conditions for 30 min in accordance with OECD guideline 209 (activated sludge, respiration inhibition test). The NOEC based on respiration inhibition was >1000 mg/L.
