From Lumbricus rubellus

Earthworms, Lumbricus rubellus, Aporrectodea rosea Earthworms absent from plats with medium and high contamination. Surface casts of L. rubellus had 17.5 mg/kg DW in low contamination soils vs. 7.0 in controls for A. rosea. These values were 13.3 vs. 7.0 120... 

Earthworms (Eisenia fetida) held in soils containing 53 mg Cu/kg DW show a 50% reduction in cocoon production in 56 days 32 mg Cu/kg soil had no effect on cocoon production (Spurgeon et al. 1994). The LC50 (56 days) value for earthworms is 555 mg Cu/kg DW soil no deaths occur at 210 mg/kg soil during this period. Copper is more toxic to Eisenia fetida than are salts of cadmium, zinc, or lead (Spurgeon et al. 1994). Copper adversely affects the earthworm Lumbricus rubellus (Ma 1984). Concentrations of 150 mg Cu/kg surface soil from an accidental spill of copper...

The maximum zinc concentration in earthworms collected from a contaminated site was 1600 mg/kg DW whole animal for uncontaminated sites it was 650 mg/kg (Beyer and Cromartie 1987). Whole-body zinc concentrations in earthworms (Dendrodrilus rubidus, Lumbricus rubellus) tended to reflect zinc concentrations in soil, although zinc accumulations in both species seem to be physiologically regulated when soil zinc values exceeded 1000 mg/kg DW (Morgan and Morgan 1988).
