Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Tetrabutane is not acutely harmful to earthworms.
NOEC (14-days) ≥ 1000 mg/kg soil dw. (OECD 207).

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:
1 000 mg/kg soil dw

Additional information

Tetrabutane was tested in an acute toxicity study with earthworms (Eisenia fetida) according to the guideline OECD 207. The study was conducted as a limit test at 1000 mg/kg soil dw., over a duration of 14 days. No mortality, pathological symptoms, changes in behaviour or biologically significant reduction in bodyweight were recorded. The NOEC was determined to be ≥ 1000 mg/kg soil dw.. Tetrabutane was therefore considered not to be harmful to earthworms.
