Enumeration of Gut Bacterial Population in Eisenia fetida Exposed to Chlorpyrifos
Earthworms being the most efficient soil organism to improve soil fertility by burrowing deeply into subsoil surfaces and then releasing it out in the form of nutrient enriched cast (Lavelle, 2011). As they are abundant in number and highly productive species, so they are keystone species in the food web of soil environment (Thakuria et al., 2010). Earthworm burrows and drilosphere act as micro...
متن کاملEcotoxicity of Sodium Arsenite on Eisenia Fetida
In this study, we performed ecotoxicity tests of sodium arsenite on soil invertebrate Eisenia fetida. Initially, broad range of sodium arsenite (0.1, 1, 10, 100mg/ml) was tested for mortality of E. fetida after 24 hours in filter paper test. The narrow range doses (0-1mg/ml) were further tested to determine the EC50 and LD50. The EC50 dose of sodium arsenite was considered at which 50% of earth...
متن کاملLiquid Chromatographic Characterization of TNT in Eisenia fetida Liquid Chromatographic Characterization of 2,4,6- Trinitrotoluene Bound Residues Extracted from Eisenia fetida
The nitroaromatic compound TNT is a common component in military munitions because of its chemical stability and comparatively safe method of manufacture. In living systems, TNT is rapidly metabolized into four identifi able and extractable compounds (2-amino-4,6dinitrotoluene, 4-amino-2,6-dinitrotoluene, 2,4-diamino-6-nitrotoluene, and 2,6-diamino-4-nitrotoluene). Exposing model organisms to T...
متن کاملToxicity and bioaccumulation of ethofumesate enantiomers in earthworm Eisenia fetida.
Earthworms represent an important food source for many vertebrates and as a result, predators may encounter toxic effects via the food chain from consumption of contaminated worms. Therefore, including an assessment of xenobiotic to worms in risk assessment procedures is advisable. Here we studied the acute toxicity, bioaccumulation and elimination of ethofumesate enantiomers in earthworm, Eise...
متن کاملShort Communication AVOIDANCE, WEIGHT LOSS, AND COCOON PRODUCTION ASSESSMENT FOR EISENIA FETIDA EXPOSED TO C60 IN SOIL
Eisenia fetida was used as a model terrestrial organism to assess the potential ecotoxicity of molecular pristine C60 in soil. Reproduction (assessed by counting cocoon numbers) was hindered only at very high C60 concentrations (5% by weight), and C60 (up to 1%) was not avoided and did not hinder earthworm growth. This suggests that E. fetida is unlikely to experience acute toxicity as a result...
