Description of key information
NOECreproduction/biomass = 37.0 mg/kg sediment dry weight
Key value for chemical safety assessment
Additional information
Chronic test on sediment dwelling organisms (OECD 218) with source substance (EC 406 -040 -9):
In accordance with GLP regulations the toxicity of the read-across substance to the sediment dwelling oligochaete Lumbriculus variegatus was investigated in a 28-day static sediment-water study (ECT 2006).
With respect to biomass and reproduction the test showed a clear dose-response relationship. For the endpoint survival there was no dose-response relationship (no mortality was observed up to the highest concentration level). Therefore no LCx-values could be calculated.
The NOEC for the parameter reproduction and biomass was determined to be 37.0 mg/kg sediment dry weight (nominal). The LOECreproduction/biomass was 111.1 mg/kg sediment dry weight (nominal).
The mean measured initial recovery found in the water-sediment system (119.0%) was calculated from the recoveries found in samples of the analysed concentration levels on day 0 of the exposure phase. This mean initial recovery differed by less than 20% from the nominal concentrations, therefore the biological results were not corrected for measured concentrations but based on nominal concentrations instead.
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.
