In total, 16 chronic data are available for 3 different species of non-arthropod soil invertebrates exposed to natural EU and North American soils. Reliable chronic NOEC/EC10 values for reproductive success range from 52 to 1091 mg added Co/kg dw, both results observed for reproduction by the pot worm Enchytraeus albidus (De Schamphelaere et al, 2008). Below are the accepted high quality studies for non-arthropod soil macro-organisms, for both the added cobalt and total cobalt values, used to calculate a geometric mean for derivation of the HC5 and terrestrial PNEC.
