Removal of N-nitrosodimethylamine precursors with powdered activated carbon adsorption
(2016-01-01)
The main objective of this study was to examine the roles of powdered activated carbon (PAC) characteristics (i.e., surface chemistry, pore size distribution, and surface area) in the removal of N-nitrosodimethylamine ...
Removal of both N-nitrosodimethylamine and trihalomethanes precursors in a single treatment using ion exchange resins
(2017-11-01)
Drinking water utilities are relying more than ever on water sources impacted by wastewater effluents. Disinfection/oxidation of these waters during water treatment may lead to the formation of several disinfection ...
Optimization of a Fungally Bioaugmented Biomixture for Carbofuran Removal in On-Farm Biopurification Systems
(2016)
Biomixtures comprise the active part of biopurification systems (BPS) for the removal of pesticide-containing wastewater from agricultural origin. Considering that biomixtures contain an important amount of lignocellulosic ...
Evaluation of a recent product to remove lipids and other matrix co-extractives in the analysis of pesticide residues and environmental contaminants in foods
(2016-06-03)
This study demonstrates the application of a novel lipid removal product to the residue analysis of 65 pesticides and 52 environmental contaminants in kale, pork, salmon, and avocado by fast, low pressure gas chromatography ...
Removal of carbofuran is not affected by co-application of chlorpyrifos in a coconut fiber/compost based biomixture after aging or pre-exposure
(2016-08)
Las biomezclas constituyen la parte biológicamente activa de los sistemas de biopurificación (BPS), que se utilizan para tratar las aguas residuales que contienen pesticidas. El objetivo de este trabajo fue determinar si ...
Fungal bioaugmentation of two rice husk-based biomixtures for the removal of carbofuran in on-farm biopurification systems
(2016-02)
The ligninolytic fungus Trametes versicolor was employed in the bioaugmentation of compost- (GCS) and
peat-based (GTS) biomixtures for the removal of the insecticide-nematicide carbofuran (CFN). Among several lignocellulosic ...
Ecotoxicological analysis during the removal of carbofuran in fungal bioaugmented matrices
(2016-02)
Biomixtures are used for the removal of pesticides from agricultural wastewater. As biomixtures employ high content of lignocellulosic substrates, their bioaugmentation with ligninolytic fungi represents a novel approach ...
Design of an optimized biomixture for the degradation of carbofuran based on pesticide removal and toxicity reduction of the matrix
(2015-12)
Pesticide biopurification systems contain a biologically active matrix (biomixture) responsible for the accelerated elimination of pesticides in wastewaters derived from pest control in crop fields. Biomixtures have been ...
Inducción de senescencia en palma aceitera Elaeis guineensis para renovación (Arecales: Arecaceae) mediante mezclas de herbicidas
(2016-06)
La palma de aceite, Elaeis guineensis Jack, es uno de los cultivos
de mayor desarrollo y expansión a nivel comercial, debido a su alta
productividad oleaginosa y su bajo costo de mantenimiento. La expansión
de palma ...
Effects of neutrophil depletion in the local pathological alterations and muscle regeneration in mice injected with Bothrops jararaca snake venom
(2005-04)
In order to study the role of neutrophils in the acute local pathological alterations induced by Bothrops jararaca snake venom, and in the process of skeletal muscle regeneration that follows, an experimental model was ...
