Ecotoxicity 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 کاملHistopathological changes in liver of Heteropneustes fossilis exposed to cypermethrin.
Cypermethrin was administered to Heteropneustes fossilis in chronic concentration to determine lesion of liver as indicators of tissue damage. The cypermethrin dose used was 1/4 of 96 hr LC50. Histopathological changes in liver ranged from vacuolization, necrosis, fibrosis of perivascular region and disposition of yellow brown grains at different time of exposure viz; 20th, 30th, 40th and 60th ...
متن کاملPotential utilization of bagasse as feed material for earthworm Eisenia fetida and production of vermicompost
In the present work bagasse (B) i.e waste of the sugar industry, was fed to Eisenia fetida with cattle dung (CD) support as feed material at various ratios (waste: CD) of 0:100 (B0), 25:75 (B25), 50:50 (B50), 75:25 (B75) and 100:0 (B100) on dry weight basis. Co-composting with cattle dung helped to improve their acceptability for E. fetida and also improved physico-chemical characteristics. Bes...
متن کاملMicrocystin toxicity in a freshwater fish, Heteropneustes fossilis (Bloch)
Microcystin is a toxin secreted by cyanobacteria, which are the dominant phytoplankton in eutrophic freshwater bodies. The present study reports histopathological, hematological and biochemical changes in the freshwater fish, Heteropneustes fossilis due to toxicity of microcystin. Toxic effects were observed in liver, kidney, corpuscles of Stannius, gills and gonads. Bilirubin concentration inc...
