The use of vermicompost for remediating soil contaminated with the commercial formulation containing deltamethrin was proposed. Biotoxicity tests with the goal of evaluating the potential remediation degree of the vermicompost after its addition to contaminated soils were performed. The tests lasted 56 days and involved Eisenia foetida earthworms. Possible structural changes in humic acids from these soils were evaluated by means of FTIR spectroscopy. The soil contaminated with deltamethrin…

As the incubation period increased, the inhibitory effect of the insecticide on the microorganisms decreased and the evolution of carbon dioxide depended on the applied dose and the percentage of evolved 14CO2 increased with time under aerobic and anaerobic conditions in both soils.
Enzymes of Earthworm as Indicators of Pesticide Pollution in Soil
A mini review is brought out which illustrates updated information available on the impact of pesticides on the activities of certain key enzymes reported to be responsible for catalysing metabolic pathways concerning the neurotransmission system, energy metabolism, oxidative stress and amino acids metabolism in different body parts of the earthworms, a prospective bioindicators of pesticides contamination in the soil.
Bioactivity of chemically transformed humic matter from vermicompost on plant root growth.
It is suggested that the hydrophobic domain can preserve bioactive molecules such as auxins in the humic matter and release bioactive compounds from humic aggregates in contact with root-exuded organic acids.
Study of Humification Dynamics of Organic Residues on Vermicomposting Process
This work aims the study of humification of three organic residues (cattle manure, orange pomace, and filter cake) submitted to vermicomposting during 6 months. Some parameters were studied such as
Deltamethrin and Permethrin in the Liver and Heart of Wistar Rats Submitted to Oral Subchronic Exposure
For 28 days male Wistar rats were submitted to oral exposure with 1/10 of the LD50 value of permethrin (PMT) or deltamethrin (DMT). The aim of this study was to determine the residues of PMT and DMT
Chemical Differentiation of Domestic Sewage Sludge and Cattle Manure Stabilized by Microbioreators: Study by Pyrolysis Coupled to Gas Chromatography Coupled to Mass Spectroscopy
The aim of the present study was to evaluate the chemical alterations in substrates of vermicomposts from domestic sewage sludge and from cattle manure, besides its quality as an organic fertilizer.
