Description of key information

LC50 (14d) > 1000 mg/kg soil dw for mortality of Eisenia fetida

NOEC (19d) >= 100 mg/kg soil dw. for seedling emergence and growth of Lepidum sativum, Brassica alba and Triticum aestivum

Additional information

Generally, the substance is not supposed to be directly applied to soil and further is readily biodegradable. Hence in case of indirect exposure to soil, the substance is expected to rapidly degrade. Therefore soil is not expected to be a compartment of concern. Thus the risk to terrestrial organisms is regarded to be negligible.

Nevertheless within the alkylethoxylate category terrestrial tests are available. This includes acute toxicity tests on earthworm (BASF, 1990) and on plant seedling emergence and growth (Sasol, 1994). Based on the results of these studies, it can be concluded that alcohol ethoxylate have a low impact on terrestrial macroorganisms and terrestrial plants.
