Description of key information

EC10(3h) > 1000 mg/L (nominal) for respiration inhibition of activated sludge (OECED 209)

Key value for chemical safety assessment

Additional information

One study investigating the toxicity of Glycerides, castor-oil mono-, di- and tri- (CAS 91744-27-3) to aquatic microorganisms is available. The study was performed according to GLP and OECD guideline 209 using non-adapted activated sludge from a predominantly municipal STP as test organism (BASF 2017). After an incubation time of 3 h no respiration inhibition were observed in any treatment. Thus, the 3h-EC10 value is determined to be > 1000 mg/L based on nominal concentrations.
