Toxicity to soil macroorganisms except arthropods

Description of key information

The NOEC or EC10 values for non-arthropod soil invertebrates of high quality that have been carried forward for the HC5 & PNEC derivation range between 46.5 mg Ni/kg and 1,140 mg Ni/kg.
 

Additional information

Toxicity to soil macro-organisms except arthropods

Chronic data are available for 4 different species of non-arthropod soil invertebrates. NOEC/EC10 values range from 46.5 mg Ni/kg for reproduction by the earthworm Eisenia fetida (University of Ghent and Euras, 2005) to 1,140 mg Ni/kg for reproduction by E. fetida (University of Ghent and Euras, 2005).  Below are the accepted high quality studies for non-arthropod soil macro-organisms used for derivation of the HC5 and terrestrial PNEC.

 

Key Study (Soil macro-organisms)	Selected values for the most sensitive endpoints used for derivation of the terrestrial HC5

University of Ghent and Euras, 2005	Eisenia fetida	46.5-1100	47.6-1140
	Eisenia fetida	46.5-1110	47.6-1140
Lock and Janssen, 2002	Eisenia fetida	180	180
	Enchytraeus albidus	180	180
	Folsomia candida	320	320
Scott-Fordsmand et al., 1998	Eisenia veneta	85	91
Scott-Fordsmand et al., 1999	Folsomia fimetaria	173	179
Ma, 1982	Lumbricus rubellus	842	859

Acute toxicity LC₅₀values range from 52 mg Ni/kg dw forLumbicis terrestris(mortality) to 2,500 mg Ni/kg dw forCaenorhabditis elegans(mortality).
