Description of key information
Toxicity to soil macroorganisms
D-8 was tested for toxicity to earthworms in a 56-d study according to ISO Guideline 11268-2. In this study no effects on mortality, growth and feeding activity of the earthworm Eisenia fetida were observed up to and including the concentration of 1000 mg D-8/kg soil dry weight. The reproduction rate of the earthworms was affected at the concentration of 1000 mg D-8/kg soil dry weight. Therefore, the overall no-observed-effect-concentration (NOEC) of D-8 was 333 mg /kg soil dry weight.
Toxicity to terrestrial plants
Based on the fresh weight, the most sensitive species was Brassica napus with an EC50 of 65.39 mg D-8/kg soil dry weight followed by Glycine max and Avena sativa with EC50 values of 302.65 and 697.15 mg D-8/kg soil dry weight, respectively. The NOEC for Brassica napus was estimated to be <10.24 mg/kg dw soil. Whereas for the other specied it was <25.6 mg/kg dw soil.
Toxicity to soil microorganisms
Based on the results of this study, D-8 had no significant impact on soil microflora carbon mineralisation up to 1000 mg/kg soil dry weight. It can be concluded that D-8 will not have any long-term influence on soil microflora. It is considered that the EC50 of D-8 is above 1000 mg/kg soil dry weight. The NOEC is considered to be equal or greater than 1000 mg/kg soil dry weight.
Additional information
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.
