In this study, earthworms Eisenia fetida were exposed to commercial NAs contaminated soil, and changes in the levels of reactive oxygen species ROS and gene expressions of their defense system were monitored. In addition, the degree of DNA damage significantly increased with increasing [C8 mim]Cl concentrations and exposure time.

The progressive signs of morphological destruction are correlated with percentage inhibition of AChE in the in vivo experiments. Cd levels increased in the exposed organisms proportionally to the concentrations and duration of exposure; this metal was mostly accumulated to the MP region. For acute exposures, the expression of one epigenetic-related gene was altered for both whole-body tissues and male reproductive organs Piwi2.

After the analysis of results, it was concluded that the neutral red retention time assay in earthworms can be used to link changes in the permeability of lysosomal membranes to ecologically relevant life cycle effects caused by such toxic substances. In earthworm tests, worms were exposed to the soils for uptake of heavy metals. The kinetics of Foteida activity in the presence and absence of azodrin indicated that the toxicant is competitive in nature.

Absorption of TEL into the tissues is comparatively less than that of lead oxide but toxic effects were severe. From week 10, however, their survival rate improved so that by week 12 when toxicity reduced to Uptake pathways and toxicity of Cd and Zn in eissenia earthworm Eisenia fetida.


The aim of the study was to determine whether humic acid HA prevented gene and biochemical toxic effects in earthworms Eisenia foetida exposed to nickel and deltamethrin at and 1 mg kg -1respectively in soil.

Evidence for proteins involved in prophenoloxidase cascade Eisenia fetida earthworms. The existence of fertile hybrids of closely related model earthworm species, Eisenia andrei and E. Significant increases in ROS levels was observed in NAs exposure groups, and the superoxide dismutase SOD and catalase CAT genes were both up-regulated at low and medium exposure doses, which implied NAs might exert toxicity by oxidative stress.

Moreover, the vermicompost produced by E. Soil cation exchange capacity and organic carbon content were identified as key factors controlling Cu toxicity to earthworm cocoon production, and simple and multiple regression models were developed for predicting Cu toxicity across soils.

The nutrient statuses of vermicomposts of all earthworm species produced from both the wastes were more than that of the compost and that of their respective substrates.

Full Text Available Interest in instrumental learning in earthworms dates back caracteritsicas when Yerkes concluded that they can learn a spatial discrimination in a T-maze.

The earthworm Eisenia fetida Then the hatchability decreased with the interval between irradiation and laying, and reached lowest level 20 days after irradiation. Lytic activities in coelomic fluid of Eisenia foetida and Lumbricus terrestris.

Possibilities of using Eisenia Andrei earthworms as bioindicators of radioactive soil contamination. Using bioindicators based on biodiversity to assess landscape sustainability. The present study focuses on identifying the potential transcripts and predicting their functional features by annotating the transcriptome dataset of nerve cord tissues prepared by Gong et al.


Earthworms were exposed to artificially contaminated soils with ten perfluoroalkyl substances PFASs. Malathion esenia chlorpyrifos exposures caused a significant decrease in NTC, lysozyme and hemolytic activities, but these variables were not affected by time of exposure.

Comet assay suggested that increasing concentrations of Pb exposure resulted in a gradual increase in the tail length and olive tail moment, which meant that the degree of DNA caarcteristicas was promoted. A possible explanation is an increased demand for energy, needed for the regulation and detoxification of herbicide.

The soil samples were foefida on 20 days, 45 days and 60 days from the day the earthworms were added.

The estuarine clam Mytella gyuanensis. Como citar este artigo. How to cite this article.

DNA damage and oxidative stress induced by imidacloprid exposure in carwcteristicas earthworm Eisenia fetida. Toxicity of selected organic chemicals to the earthworm Eisenia fetida.

Soil stabilization does not remove heavy metals from contaminated soil, but lowers their exposures to ecosystem. Current bioremediation techniques for petroleum-contaminated soils are designed to remove contaminants as quickly and efficiently as possible, but not necessarily with postremediation soil biological quality as a primary objective.

An enzyme from the earthworm Eisenia fetida is not only a protease but also a deoxyribonuclease. On a soil concentration basis, the toxicity of the binary combinations of distillates was less than additive.
