“…The same effect was observed for the toxicity of heavy metals (in particular copper) for earthworms [12–15]. Accumulation of heavy metals at sublethal levels by earthworms was found to depend on the total content, rather than the (easily) dissolved fraction [15]. Hence, the pH‐dependency of copper adsorption was not reflected in a pH‐dependency of copper accumulation by earthworms.…”

“…Effects of Cu on nematodes increased as pH‐values decreased [11], probably because Cu‐adsorption is less and Cu‐fractions in solution are larger than at high pH. The same effect was observed for the toxicity of heavy metals (in particular copper) for earthworms [12–15]. Accumulation of heavy metals at sublethal levels by earthworms was found to depend on the total content, rather than the (easily) dissolved fraction [15].…”

We investigated the accumulation of copper (Cu) by the springtail Folsomia candida Willem, if exposed to Cu-contaminated sandy soil with yeast as a food source. Commonly, the dissolved and the easily desorbed Cu fractions are assumed to be available for uptake, and as both fractions depend on pH, a pH dependency of copper uptake and accumulation is expected. In recent studies with springtails this dependency was not observed. To explain this, we show that both the adsorption of copper by yeast and by soil is indeed pH dependent; however, these dependencies differ. Addition of yeast as a food source to copper-contaminated soil leads to competition for copper by yeast and soil that suppresses the pH dependency of copper adsorption by yeast. This may cause a pH dependency not to be observed in copper accumulation by springtails if they predominantly feed on yeast in bioassays. We conclude that the addition of artificial food sources in bioassays may affect the cause-effect relationships that are investigated. A combination of (soil) chemical experimentation and modeling and ecotoxicological studies may help in identifying such bias and, therefore, with interpreting bioassays.

“…Hence, in soils contaminated with a mixture of heavy metals, adsorption interactions may change the bioavailability of each heavy metal compared to soils contaminated with only one heavy metal. The toxicity of heavy metal polluted soil for earthworms increases with decreasing pH (Ma, 1984;Bengtsson et al, 1986;Marinussen et al, 1997a) which suggests that the heavy metal availability is determined by heavy metal concentrations in soil solution. Tissue Cu accumulation data, however, do not support this suggestion as observed in a laboratory study by Marinussen et al (1997a).…”

Orchard soils can contain elevated concentrations of 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (p,p'-DDE), 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (p,p'-DDT), and heavy metals as a result of historical agrichemical applications. The bioavailability of p,p'-DDE, p,p'-DDT, As, Cd, Cu, and Pb from five field-aged New Zealand orchards and three grazing soils was assessed by using a 28-d bioassay with Aporrectodea caliginosa and chemical assays. Significant relationships were found between total soil and earthworm tissue concentrations for p,p'-DDE (p < 0.001), p,p'-DDT (p < 0.001), Cu (p < 0.001), and Pb (p < 0.01). Two neutral salt solutions, 0.01 M CaCl(2) and 1 M NH(4)NO(3), were used as surrogate measures of the bioavailability of heavy metals. Copper was the only heavy metal for which significant correlations were found between neutral-salt-extractable and earthworm tissue concentrations (p < 0.001). Up to 28% of the aged DDT residues were released from the soils by Tenax over a 24-h extraction period. Significant relationships (p < 0.01) between the Tenax-extractable and earthworm tissue concentrations for p,p'-DDE and p,p'-DDT showed that Tenax provides a good surrogate measure of the bioavailability of these compounds to A. caliginosa. Surprisingly, there was a similarly significant relationship (p < 0.001) between the total soil and earthworm tissue concentrations for p,p'-DDE and p,p'-DDT, suggesting that total soil concentrations alone were sufficient to predict uptake by A. caliginosa. These results demonstrate that the aged agrichemical residues in orchard soils, and particularly p,p'-DDE and p,p'-DDT, remain highly bioavailable to A. caliginosa despite decades of weathering and continue to present an environmental risk.
