Earthworms 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...
متن کاملThe Soil Pollutants
We consider as a pollutant any chemical of natural or anthropogenic origin which accumulates in the soil medium and changes the natural soil equilibrium, as a result of human activity. A modern society, however, cannot be developed without the use of natural and synthetic compounds which may be added to the various ecosystems. The art of safeguarding the environment consists of minimizing the a...
متن کاملImproved Performance of Soil Microbial Fuel Cell by Adding Earthworms
Soil microbial fuel cells (SMFCs) are expected as an application to produce sustainable energy. Here, we focused on soil ecosystems, specifically the earthworms which are known to improve soil-fertility by degrading fallen leaves or plant litter. The aim of this study was to investigate the effect of earthworm on power generation of the SMFC. The maximum power density and the internal res...
متن کاملEffects of endogeic earthworms on the soil organic matter dynamics and the soil structure in urban and alluvial soil materials
chlorotica Aporrectodea rosea X-ray tomography Burrow networks Microcosms Earthworms are considered as key actors of soil processes at different spatial and temporal scales and provide essential ecosystem services linked to climate regulation or primary production. However, little is known about their basic functional roles (e.g. organic matter decomposition, soil structuring processes) in pert...
متن کاملBiochemical and genotoxic effect of triclosan on earthworms (Eisenia fetida) using contact and soil tests.
Triclosan (TCS) is a broad-spectrum bactericide that is used for a variety of antimicrobial functions. TCS is frequently detected in the terrestrial environment due to application of sewage sludge to agricultural land. In the present study, 48-h paper contact and 28-day spiked soil tests were conducted to examine the toxic effects of TCS on the antioxidative and genetic indices of earthworms (E...
