Autor: Ana Lozano, Samanta Uclés, María Dolores Gil García, Amadeo R. Fernández-Alba, M. Martínez Galera
Publikováno v: Analytical and Bioanalytical Chemistry. 410:5195-5210
In this work, 260 pesticide residues, including insecticides, acaricides, fungicides, and herbicides, were extracted from honeybees using the QuEChERS methodology modified by applying an ultrasonic probe, which avoided the homogenization step and red

Publikováno v: Environmental pollution (Barking, Essex : 1987). 235
During the last years, declines in honey bee colonies are being registered worldwide. Cholinergic pesticides and their extensive use have been correlated to the decline of pollinators and there is evidence that pesticides act as neuroendocrine disrup

Enhanced high-performance liquid chromatography method for the determination of retinoic acid in plasma. Development, optimization and validation
Autor: Héctor C. Goicoechea, María Dolores Gil García, Carla Mariela Teglia, M. Martínez Galera
Publikováno v: Journal of Chromatography A. 1353:40-48
When determining endogenous compounds in biological samples, the lack of blank or analyte-free matrix samples involves the use of alternative strategies for calibration and quantitation. This article deals with the development, optimization and valid

Determination of eight pesticides of varying polarity in surface waters using solid phase extraction with multiwalled carbon nanotubes and liquid chromatography-linear ion trap mass spectrometry
Autor: Aicha Derdour, Ana Uclés Moreno, María del Mar Socías Viciana, Soraya Dahane, María Dolores Gil García, M. Martínez Galera
Publikováno v: Microchimica Acta. 182:95-103
We describe a MWCNT-based method for the solid-phase extraction of eight pesticides from environmental water samples. The analytes are extracted from 100 mL samples at pH 5.0 (containing 5 mmol L−1 of KCl) by passing the solution through a column f
