CAS No 68513-69-9 and 68921-67-5: After Daphnia magna were exposed to WAFs prepared from Pyrolysis C10+ Fuel Oil for 48 hours, the EL50 was 1.2 mg/L and EC50 was 1.2 mg/L. This study was GLP compliant and followed a standard guideline. It is considered reliable and suitable for use as a key study.
CAS No 68513-69-9: The 48 hour EL50 was determined to be 3.3 mg/L and the 48 hour EC50 was determined to be 2.7 mg/L. This study is GLP compliant and follows a standard guideline. The nature of the stream was taken into account and WAFs were used. This study is considered reliable and suitable for use as a supporting study.
