Depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge are possible.EC20 (30 min) ca. 7 mg/L and EC50 (30 min) ca. 130 mg/L (nominal) for activated sludge (OECD 209)
For the Sulfonium copound mixture
the influence on the respiration of microorganisms was investigated in a
GLP guideline study according to OECD 209 (Activated
Sludge, Respiration Inhibition Test) [BASF
AG, 2003]. The study was conducted with activated sludge from
laboratory wastewater plants treating municipal sewage. After
30 minutes of incubation the EC20 was ca. 7 mg/L and the EC50 was ca.
130 mg/L based on nominal concentration.
