Ecotoxicological assessment of TiO2 byproducts on the earthworm Eisenia fetida
Environmental Pollution, 2011The increasing production of nanomaterials will in turn increase the release of nanosized byproducts to the environment. The aim of this study was to evaluate the behaviour, uptake and ecotoxicity of TiO(2) byproducts in the earthworm Eisenia fetida. Worms were exposed to suspensions containing 0.1, 1 and 10 mg/L of byproducts for 24 h.

Sludge earthworm composting technology by Eisenia fetida
Journal of Material Cycles and Waste Management, 2013Prior to vermicompost application to the soils, there is a need to determine the heavy metal concentrations in the final vermicomposts. Acute toxicity on Eisenia fetida for copper (Cu) and cadmium (Cd) were conducted by artificial soils tests. The dosage of interest is typically the median lethal concentration (LC50) that will kill 50 % of the ...

Genotoxicity of two novel pesticides for the earthworm, Eisenia fetida
Environmental Pollution, 2000In this paper, several studies were conducted to evaluate the genotoxicity of two pesticides, Imidacloprid and RH-5849, for earthworm (Eisenia fetida). Earthworms were exposed in different exposure systems to evaluate their acute toxicity and the genotoxicity of the two pesticides was evaluated by using the method of sperm deformity assessment ...

Toxicity and transformation of insecticide fenamiphos to the earthworm Eisenia fetida
Ecotoxicology, 2010This study was conducted to investigate the toxicity of the organophosphate insecticide fenamiphos to earthworms (Eisenia fetida) under laboratory conditions. Earthworms were exposed to soils differing in their physico-chemical properties spiked with fenamiphos at concentrations ranging from 10 to 200 mg kg(-1) for a period of 4 weeks.

Assimilation by the earthworm Eisenia fetida
1983Eisenia fetida(Savigny) is an earthworm which grows rapidly (Neuhauser et al., 1980), reproduces prodigiously (Hartenstein et al., 1979), is potentially deployable for management of wastes rich in microbial biomass (Hartenstein, 1981a, b), and is possibly more efficient on a time-space scale for production of animal (meat, in contrast to eggs and milk)
