Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:
5 000 mg/kg soil dw

Additional information

The toxicity to soil macroorganisms except arthropods was evaluated by considering data on two similar substances. Justification for Read Across is given in Section 13 of IUCLID.

A study is available to assess the acute toxicity of the similar 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, conducted also according to OECD 207 in which LC50 was greater than 3000 mg/kg dry weight and for which also a summary for the same test is available (Solvias AG., 1999).No concern for soil toxicity is then arisen by the presented acute studies.
