Description of key information

Short-trerm toxicity:

The results indicate that the substance is not toxic to soil macroorganisms (read-across to CAS 1328 -53 -6, BASF SE, rep. no.: 99/0565/67/1, 2000)

Long-term toxiciy: no data available.

Key value for chemical safety assessment

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

Additional information

Short-trerm toxicity:

To assess the acute toxicity of CAS 27614 -71 -7 to terrestrial macroorganisms (arthropods not included), the read across was performed to the structural similar substance CAS 1328-53-6.

In a guideline study according OECD 207 on Eisenia foetida the analogue CAS 1328-53-6 was mixed with artificial soil and the earthworms were kept on the soil/substance mixture for 14 days. A NOEC >= 1000 mg/kg soil was determined (BASF SE, rep. no.: 99/0565/67/1, 2000). The results indicate that the substance is not toxic to soil macroorganisms (arthropods excluded).

Long-term toxiciy:

In Annex XI of Regulation (EC) No 1907/2006, it is laid down that there may be sufficient weight of evidence from several independent sources of information leading to the assumption/conclusion that a substance has or has not a particular dangerous property, while the information from each single source alone is regarded insufficient to support this notion. in this case, the substance has a low potential for adsorption to soil particles and it has no bioaccumulative properties based on the logKow clearly below 3. Based on these data, binding to sewage sludge is unlikely and as a consequence a transfer to the soil compartment is not expected. Additionally, the lack of any harmful effects in aquatic tests on all three trophic levels at concentrations below the solubility in water indicate a low hazardous potential of the test substance towards soil organisms. Finally, according to REACH Annex X column 2, the study does not need to be conducted if direct and indirect exposure of the soil compartment is unlikely. The substance is not applied directly to soil and is not expected to be transferred indirectly to soil in significant quantity. Therefore, the risk to soil organisms is considered negligible and no further tests on terrestrial organisms are provided.
