Description of key information

the substance is considered to be acutely not harmful to terrestrial macroorganisms

Key value for chemical safety assessment

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

Additional information

A study on a close structural analogue (CAS 16090 -02 -1) is available in order to determine the acute toxicity of the substance to terrestrial macroorganisms. The EC50 value in Eisenia foetida according to OECD 207 was greater than 1000 mg/kg dry weight.

Therefore, the substance CAS 133 -66 -4 is considered to be acutely not harmful to terrestrial macroorganisms.
