Description of key information

EC10 (3 h): 580 mg/L based on the respiration rate of activated sludge microorganisms (OECD 209)

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
580 mg/L

Additional information

One experimental study investigating the inhibition of the respiration of diethyleneglycol diformate (CAS 120570-77-6) to activated sludge microorganisms is available (Roulstone, 2012). The study was conducted according to OECD 209 under GLP conditions using activated sludge from a sewage treatment plant treating predominantly domestic sewage. Five concentrations up to 1000 mg/L (nominal) were tested. After 3 h contact time diethyleneglycol diformate resulted in an EC10 of 580 mg/L based on the respiration rate.
