Description of key information

LC50 (14 d) > 5000 mg/kg soil dw

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:
3 000 mg/kg soil dw

Additional information

A study is available to assess the acute toxicity of the analogue substance 3a-A(Na) to terrestrial macroorganisms. The LC50 value in Eisenia foetida according to OECD 207 was greater than 5000 mg/kg dry weight (Solvias AG., 1999). The reliability is low because just the summary is actually available.

Nevertheless the study is supported by the test on the similar substance 3a-MSA, for which also a summary for the same test is available (Solvias AG., 1999).

Justification for Read Across is given in Section 13 of IUCLID.

No concern for soil toxicity is then arisen by the presented acute studies.
