Description of key information
Additional information
Tests on various terrestrial species (earthworm, collembolen, terrestrial plants and soil microorganisms) have been conducted.
For earthworm, an LC50 of 850 mg/kg dw was calculated for a 14 d exposure duration.
In the study on collembolen (Folsomia candida), the lowest NOEC was found to be 100 mg/kg dw or 320 mg/kg dw for mortality and reproduction, respectively.
For terrestrial plants no effect on seedling and emergence was observed at the highest tested concentration of 100 mg/kg dw.
In the soil microorganisms study, the NOEC is considered to be equal to or greater than 515.4 mg test item/kg soil dry weight.
Thus, the lower NOEC = 100 mg/kg dw will be used to derive a PNECsoil.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
