Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Key value for chemical safety assessment
Additional information
Information on short term toxicity to fish was available for vacuum gas oils, hydrocracked gas oils and distillate fuels. The 96h LL50 for freshwater fish is 21 mg/L. This data is from Shell report 6304 (1996). This is the most conservative value from the two key studies. This study is considered reliable (2), it is a GLP compliant, near guideline study, with minor restrictions in design and/or reporting but otherwise adequate for assessment.
A wide range of values have been reported for the supporting studies which cannot be compared directly because the studies vary in design, test species and different endpoints have been investigated. Although the Exxon 142958 (1998) study reported a lower LL50, this was not selected as a key study because insufficient data was available to confirm that the test validity criteria were met.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
