Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Any other information on results incl. tables

The LD50 values for acrylonitrile administered by parenteral routes are broadly comparable with the reported acute oral LD50 values.

Applicant's summary and conclusion

Conclusions:
The LD50 values for acrylonitrile administered to various species by parenteral routes are broadly comparable with the reported acute oral LD50 values.
Executive summary:

LD50 values are reported for acrylonitrile administered via the subcutaneous, intraperitoneal or intravenous routes to rats, guinea pigs, hamsters, mice and rabbits. The values for these routes of administration are similar to those for oral administration and therefore are consistent with rapid and extensive absorption following oral administration.
