Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The effect of the test item on the earthworm reproduction was assessed according to an OECD test n°222. The results obtained allowed to conclude that, taking into account the mortality, the growth and the reproduction of the exposed adults test organisms, the highest concentration of the test item without inhibitory effect on Eisenia fetida after the test period was determined to be, at least, 1 000.0 mg/ kg dry soil (highest tested concentration).

The effect of the test item on the nitrogen transformation activity of the soil microorganisms shown an EC50 of greater than 1000 mg/kg dry weight according the OECD 216 Guideline.

According to ECHA guide R7C, the test species should ideally cover different habitats and feeding modes in the soil as well as different taxonomic groups. For strongly adsorbing or binding substances soil-dwelling organisms that feed on soil particles (e.g. earthworms) are most relevant.

Plants are exposed mainly by a soil pore water pathway, whearas earthworms are exposed to the substance by diverse and multiple uptake routes (soil pore water, ingestion of soil material, soil air, secondary poisoning).

Furthermore, the substances in the category are highly insoluble; for uptake by plants, the substance needs to go into solution (interstitial or pore water) before exposure can occur, therefore testing the substances in plants is considered irrelevant.

So other terrestrial test are not needed.
