“…The present study showed that the total number of nematodes did respond to an increase in Cu-CaCl 2 , although earlier reports suggested that the total number of nematodes is not a sensitive indicator of heavy-metal pollution [30,31]. The most likely reason for this discrepancy is the difference in bioavailability, which emphasizes the advantage of the CaCl 2 extraction method.…”

Abstract-Four copper (0, 250, 500, and 750 kg Cu·ha Ϫ1 ) and pH (4.0, 4.7, 5.4, and 6.1 in 1 M KCl) treatments were applied to an arable agroecosystem. Effects on the nematode community were assessed after 10 years of exposure under field conditions. Both copper and pH had major influences on nematodes. The effect of copper was generally enhanced with decreasing soil pH. The lowest copper application rate which had a significant negative effect on the total number of nematodes was 250 kg·ha Ϫ1 at pH 4.0, which is equivalent to a copper concentration of 0.32 mg·L Ϫ1 in 0.01 M calcium chloride (Cu-CaCl 2 ). Species composition and the abundance of trophic groups were more sensitive than the total number of nematodes. Combinations of high copper and low pH significantly reduced the number of bacterial-feeding nematodes, whereas the number of hyphal-feeding nematodes increased. Omnivorous and predacious nematodes showed the most sensitive response, becoming extinct when Cu-CaCl 2 was 0.8 to 1.4 mg·L Ϫ1

“…Spurgeon & Hopkin (1996a) found a significant reduction in earthworm abundance at sites within 2 km of the Avonmouth smelter, while Bengtsson, Nordstr‘m & Rundgren (1983) found lower total numbers and biomass in soils around a brass mill. Bisessar (1982) and Hunter, Johnson & Thompson (1987) found decreased abundance of worms in soils near a lead smelter and copper refinery, respectively.…”

“…These include studies undertaken to quantify community change in major invertebrate groups along metal contamination gradients [7,56], as well as studies with specific soil taxa like earthworms [57][58][59], springtails [8,60], mites [61], ground beetles [62] and spiders [63]. Changes observed in these studies included reduced overall abundance (including the presence of deserts for some groups), lower diversity as assessed using traditional metrics, altered community composition and changes in species dominance structure [64].…”
