Description of key information
PR208
Toxicity to soil macroorganisms
Effects of the test item on mortality, biomass and the reproductive potential of the earthworm species Eisenia fetida (Savigny) were determined according to the Guideline OECD 222 (2004).
Under the conditions of this study, the test item did not induce mortality, pathological symptoms or changes in the behaviour of adult earthworms after 28 days of exposure at the limit test item concentration. The adult earthworm biomass increased in the control and at the limit test item concentration without any statistically significant differences. After eight weeks of exposure the earthworm reproduction at the limit test item concentration did not statistically significantly differ to the controls.
Thus, the No Observed Effect Concentration (NOEC) for the test item summarizing the endpoints mortality, body weight and reproduction of Eisenia fetida fetida after 8 weeks of exposure in artificial soil was determined to be >1000 mg /kg soil dry weight.
Toxicity to terrestrial plants
The phytotoxicity of the test item to three terrestrial plant species was determined in a seedling emergence test over a period of 21 days according to OECD 208.
The test was conducted with the limit concentration 1000 mg/kg soil dry weight (DW). Test systems were one monocotyledon, oats (Gramineae), and two dicotyledons, rape (Brassicaceae) and soybean (Leguminosae).
After 21 days no test item related phytotoxic effects were determined for all tested plant species at and up to the concentration 1000 mg/kg DW.The NOEC was determined for shoot height, shoot fresh weight and rate of emergence for all tested plant species.
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.
