(48h) EL50 >100 mg/L (D. magna)
Key value for chemical safety assessment
Additional information
The short-term toxicity of GTL Base Oil Distillates with the freshwater invertebrate Daphnia magna (water flea) has been determined in a study conducted in accordance with OECD Test Guideline 202.
WAFs of the sample were prepared by stirring for approximately 23 hours and left to stand for 1 hour before drawing off the aqueous phase – the WAF – for testing. Static exposures were then carried out according to GLP.
Total Organic Carbon (TOC) analysis of the freshly prepared test preparations showed amount of carbon present within the control and the 100 mg/l loading rate WAF test vessels to be less than the limit of quantitation (LOQ) for the method within fresh and old media. Therefore the results from the TOC analysis did not provide definitive evidence of the stability of the test preparations.
The test results, expressed as the EL50value, showed that the sample was not hazardous to Daphnia magna at a loading rate of 100 mg/l.
