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.

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.
