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 48hr EL50 was determined to be 3.3mg/l and the 48hr EC50 was determined to be 2.7mg/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.
