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 کاملMorpho-Histopathological Response of Phorate- An Organo-Phosphorous Pesticide on the Integumentary Musculature of an Epigeic Earthworm, Eisenia fetida
Synthetic pesticides are fairly well recognized as a cost-effective method of controlling pests, but these chemicals are toxic to other non-targeted and beneficial species. Pesticides are either directly applied to soil to control soil borne pests or deposited on soil as runoff from their foliar applications and these concentrations are highly enough to effect soil micro-organisms (Bezchlebova ...
متن کاملInfluence of Soil Characteristics on Biomass Growth and Reproduction of Earthworm Eisenia fetida
It is known that in vermicomposting soil layer in bedding of the reactor helps in earthworm biomass growth and reproduction but growth is influenced by soil characteristics such as texture, pH, and water holding capacity. The present study was conducted to asses the influence of soils on earthworm biomass growth and reproduction during the vermicomposting of source separated human faeces. The s...
متن کاملEffects of bifenthrin exposure in soil on whole-organism endpoints and biomarkers of earthworm Eisenia fetida.
In this study, toxic effects of bifenthrin in soil on earthworms were evaluated by acute and chronic toxic endpoints combined with a set of biomarkers. Bifenthrin was moderately toxic in 72-h filter paper test and low toxic in 14-d soil test. The exposure of earthworms to bifenthrin-polluted soil for 8 weeks showed that cocoons were inhibited by high dose of bifenthrin, and larvae were stimulat...
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...
