In contaminated soils, no significant mortality was observed, except in soils which have very low pH earthworms exposed to several of the contaminated soils. Addition of earthworms resulted in greater total respiration of all soil and straw treatments except two the land-farm and the 1: Silver nanoparticles are widely used in a range of consumer products mainly The earthworms were exposed to 3 nanoparticles: This study demonstrated that azodrin causes concentration-dependent changes in the morphology and AChE activity of the earthworm E.

Insufficient information existed to generate Eco-SSLs for explosives and related materials in soil.

Eisenia andrei (Oligochaeta) as bioindicator of soil contamination by hexachlorobenzene (HCB)

Biochar was less effective at immobilising PTEs, due to its low cation exchange capacity. The total petroleum hydrocarbon TPH content of each soil was measured by latroscan before the dilutions were prepared.

This study demonstrated that earthworms accelerate bioremediation of crude oil in soils, including the degradation of the heaviest polyaromatic fractions. EE – Microbiology, Virology Impact factor: After the 7 days of elimination phase, subcellular partitioning of metals were also obtained. A possible explanation is an increased demand for energy, needed for the regulation and detoxification of herbicide.


The mean earthworm biomass was found to be decreased with increasing herbicide concentration.

Características da minhoca Eisenia foetida – Benefícios e mais-valias ambientais

Studies on the organic All earthworms in the exposed group were found to have glandular cell enlargement and to be vacuolated.

Full Text Available A laboratory microcosm experiment was conducted to determine whether the earthworm Eisenia foeida could survive in a saline soil from a field site in North China, and an experiment using response surface methodology was conducted at that field site to quantify the effects of E.

More specifically, the environmental fate and transport of CAP between soil and earthworms was monitored during the exposure period.

This study aimed to determine acute and sub-acute toxicity to earthworm Eisenia fetida induced by BDE and Pb in natural soil.

After 28 days of exposure to soils, worms were transferred to clean soils for elimination. NK-like coelomocytes isolated from E.

MDA content in treatment groups was higher than in the control group throughout the exposure time, suggesting that DBP may lead to lipid peroxidation LPO in cells.

Transformation and degradation of pesticides in soil. The present study shows that [C8 mim]Cl caused biochemical and genetic toxicity in earthworms. The genes studied in this research played a caracteristcias in endocrine pathways, detoxification mechanisms, stress response, epigenetics, and genotoxicity.

Concentration of chromium and cadmium pollution in soil was determined to be 0. The pore-water concentration of most PAHs was higher than predicted. Leaded gasoline contains tetra ethyl lead TEL as an antiknocking agent, which produces major amounts of lead oxide in automobile exhaust along with traces of TEL.


Recently there has been public concern on the presence in the environment of depleted uranium DUa by-product of the process used to enrich natural uranium ore for use in nuclear reactors and in nuclear weapons. Crude oil with a high fraction of light-weight hydrocarbons was more toxic to earthworms than the crude oil with a high proportion of heavy polyaromatic eiseenia aliphatic hydrocarbons.

Correlation between the activity of digestive enzymes and nonself recognition in the gut of Eisenia andrei earthworms.

Immunogold particle density was similar along the whole thick filament length in insect caracterissticas muscle but it predominated in filament tips of fusiform thick filaments in both snail heart and earthworm body wall musculature when these filaments were observed in longitudinal sections.

The evaluated endpoints included: Filter paper was renewed at 24 h to prevent coprophagy. The enzyme isolated by this procedure showed pale blue-green color. Mortality of the earthwormsEisenia foetidaafter gamma-irradiation at different stages of their life history.

The complete functional annotation of this nerve cord transcriptome can be further utilized to interpret genetic and molecular mechanisms associated with neuronal development, nervous system regeneration and nerve cord function. A number of methods recently have been developed to biologically evaluate the impact of man’s activities on soil ecosystems. However, previous work has demonstrated less-than-additive toxicity with PHC distillates and earthworms.

The hormetic dose-response relationships induced by environmental toxic agents are often characterized by low-dose stimulation and high-dose inhibition.

Potential utilization of bagasse as feed material for earthworm Eisenia fetida and production of vermicompost.
