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.
