Description of key information
Two endobenthic organisms, the worm Lumbriculus variegatus and the abundant nematode Caenorhabditis elegans, were used to determine a potential sediment toxicity of C20/22 ATQ.
Key value for chemical safety assessment
- EC10, LC10 or NOEC for freshwater sediment:
- 62.5 mg/kg sediment dw
Additional information
The worm Lumbriculus has a NOEC being lower than the NOEC of the nematode (62.5 mg/kg dw. and 250 mg/kg dw.). The NOEC of the worm Lumbriculus variegatus of 62.5 mg/kg dw. is choosen as a basis for the PNEC freshwater sediment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
