Toxicity to soil macroorganisms except arthropods

Additional information

Toxicity to soil macro-organisms except arthropods

Chronic data are available for different species of non-arthropod soil invertebrates. NOEC/EC₁₀values range from 2.6 mg Ni/kg for hatching by Enchytraeus crypticus (Santos et al, 2017) to 1140 mg Ni/kg for reproduction by E. fetida (Ghent University and Euras, 2005).  Below are the accepted high quality studies for non-arthropod soil macro-organisms used for derivation of the HC₅and terrestrial PNEC:

 

Key Study (Soil macro-organisms)	Selected values for the most sensitive endpoints used for derivation of the terrestrial HC5
	Species	Added NOEC or EC10 (mg/kg dw)	Total NOEC or EC10 (mg/kg dw)
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 for Lumbicis terrestris (mortality) to 2,500 mg Ni/kg dw for Caenorhabditis elegans (mortality).
