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
Earthworm
OECD 207
The acute effects of Licocare RBW 300 on the earthwormEisenia fetidawere determined according to the OECD Guideline 207
No mortality and no pathological symptoms or changes in earthworm behaviour were observed in the control and the limit test item concentration after 14 days of exposure. Therefore, the NOEC was determined to be 1000 mg test item/kg SDW.
In terms of body weight loss, no statistically significant effect was observed in the limit test item concentration after 14 days of exposure compared to the control. Consequently, the NOEC was determined to be 1000 mg test item/kg SDW.
OECD 222
Under the conditions of this study, neither earthworm mortalities nor pathological symptoms or changes in the behaviour of adult earthworms were observed in the control or all test item concentrations. There were no statistically significant differences in biomass in all test item concentrations compared to the control. After a further four weeks, the reproduction rate (average number of juveniles produced) was 155 in the control and ranged from 141 to 159 in the test item treatment rates. There were no statistically significant differences in earthworm reproduction in all treatment rates compared to the control. No effect values could be determined for biomass, reproduction and mortality, as no effects occurred up to 1000 mg test item/kg SDW.
All validity criteria recommended by the test guidelines were fulfilled.
Terrestrial Plants
Waiving: study scientifically not necessary / other information available
A short-term study does not need to be conducted because an appropriate long-term toxicity study on terrestrial organisms is available. No hazard identified in aquatic systems. Two toxicity to soil macroorganisms tests (OECD 207 and OECD 222) are available and also show no hazard. It can therefore be assumed that there will be no hazard to terrestrial plants.
Soil microorganisms

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.
