Impact of earthworms on trace element solubility in contaminated mine soils amended
16 The common practice of remediating metal contaminated mine soils with compost can reduce 17 metal mobility and promote re-vegetation, but the effect of introduced or colonising 18 earthworms on metal solubility is largely unknown. We amended soils from an As/Cu (1150 19 mgAs kg and 362 mgCu kg) and Pb/Zn mine (4550 mgPb kg and 908 mgZn kg) with 0, 20 5, 10, 15 and 20 % compost and then intro...

The common practice of remediating metal contaminated mine soils with compost can reduce metal mobility and promote revegetation, but the effect of introduced or colonising earthworms on metal solubility is largely unknown. We amended soils from an As/Cu (1150 mg As kg(-1) and 362 mg Cu kg(-1)) and Pb/Zn mine (4550 mg Pb kg(-1) and 908 mg Zn kg(-1)) with 0, 5, 10, 15 and 20% compost and then in...
متن کاملCollagen of the Earthworms
The problem of the complex configuration of the collagen in the Oligochaeta has not yet been conclusively solved. Since the last century, evidence has been found of a fibrous structure lying above the epidermis (constituting the cuticle) and of another one lying below it (constituting the supporting structures). The cuticle, easily examined by physical and chemical methods, was analyzed minutel...
متن کاملPurification of Enzymes from Earthworms
Earthworms are a very rich source of enzymes useful for bioremediation of contaminated soils, in animal feeds for improving the digestion of proteins, lipids and carbohydrates, in detergents, in the saccharification of starch, and in human and animal therapeutics. Powdered earthworms are very popular in the Orient due to their properties as antipyretic, diuretic and fibrinolytic. However, in or...
متن کاملEarthworms and Soil Pollutants
Although the toxicity of metal contaminated soils has been assessed with various bioassays, more information is needed about the biochemical responses, which may help to elucidate the mechanisms involved in metal toxicity. We previously reported that the earthworm, Eisenia fetida, accumulates cadmium in its seminal vesicles. The bio-accumulative ability of earthworms is well known, and thus the...
