Recognized as ubiquitous contaminants in soil, the environmental risk of phthalic acid esters (PAEs) is of great concern recently. Effects of di-n-butyl phthalate (DnBP), an extensively used PAE compound to Eisenia fetida have been investigated in spiked natural brown yellow soil (Alfisol) for soil contact test. The toxicity of DnBP to E. fetida on the activity of superoxide dismutase (SOD) act...

An acid metal-contaminated soil from the Aljustrel mining area (a pyrite mine located in SW Portugal in the Iberian Pyrite Belt) was subjected to chemical characterisation and total metal quantification (Cd, Cr, Cu, Ni, Pb and Zn). Water-soluble metals were determined and a sequential extraction procedure was used to investigate metal speciation. Two bioavailable metal fractions were determined...

Sludge management is considered a difficult and challenging task priority of environmental policy. This study evaluates the transformation anaerobic sludge agroindustrial wastes (cow manure, mixtures) directly to compost using Eisenia fetida earthworms (vermicomposting) in relation quality; moreover, it investigates effects different compositions on vermicompost physicochemical properties. In p...

Hermaphroditic lumbricid Eisenia sp. earthworms are ubiquitous and highly resistant to a variety of environmental stressors, including heavy metals. Among the progeny laboratory mated inter-specific pairs fetida (Ea) andrei (Ef) there fertile Ha hybrids derived from Ea ova fertilized by Ef spermatozoa very rare sterile Hf spermatozoa. The aim first part experiment was compare life traits whole ...

Arsenic (As) is broadly distributed due to natural and anthropogenic sources, it toxic organisms. This study aimed investigate the proteomic response in earthworm exposed As3+. Earthworms were As3+ soil at 5–80 mg kg?1, samples collected after 60 days exposure. Two-dimensional electrophoresis (2-DE) was used separate proteins homogenate, then differentially expressed (DEPs) identified using MAL...
