Description of key information
EL50(72h) = 20.68 mg/L (nominal, loading rate) for growth rate inhibition of Pseudokirchneriella subcapitata (OECD 201)
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 20.68 mg/L
Additional information
One study investigating the algal toxicity of Glycerides, castor-oil mono-, di- and tri- (CAS 91744-27-3) is available. The study was performed according to GLP and OECD guideline 201 using Pseudokirchneriella subcapitata as test organism (Bak 2018). Loading rate WAFs in the range of 4.69 to 150 mg/L were tested. Based on nominal concentrations, the 72h-EL50 value for growth rate inhibition is determined to be 20.68 mg/L. The EL10 value is lower than the lowest concentration tested of 4.68 mg/L. However, the NOELr/ EL10 of < 4.69 mg/L is not considered to be of biological relevance. The 2 lowest concentrations showed significant differences to the control; however, the growth of both concentrations were still higher than 16-fold. This indicates that the unusual high growth rate within the control (increased by a factor of 127.4 within the 72-hour test period) generated this statistical artifact. Thus, the 72h-NOELr/EL10 value is not considered to be reliable and is not used for the hazard assessment of the test substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
