Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Description of key information

Eisenia foetida: LC50=0.1 - 1mg/cm2

Key value for chemical safety assessment

Additional information


Based on the use pattern for this substance, direct and indirect exposure of soil is unlikely. Fugacity level 3 modelling using realistic mass flow splits (see chapter 5.4.3) predicts that concentrations in soil would be less than 2% of that in the water compartment. Based on this low exposure and the fact that good data is available for the aquatic compartment, the equilibrium partitioning method is considered adequate to estimate the toxicity to soil macro-organisms based using the existing aquatic toxicity hazard data as a starting point and this end point is considered complete. There is some test data available summarised below but the results from this cannot be converted into a useable format for risk assessment purposes.

In a study designed to evaluate the toxicity of ethanol (and a large number of other chemicals) to terrestrial macro-organisms, the earthworm Eisenia foetida was exposed to concentrations of the chemical loaded on to a filter paper lining a glass vial for 48 hours in the dark. The paper was dosed with the test substance before placing in the vial in the tube. Results were expressed in quantity per unit area of the paper insert and the result for ethanol was an LC50 of between 0.1 and 1.0mg/cm2. It is impossible to calculate this as a toxicity per kg of soil as the latter was not used in the study.
