Analytical methods of biological monitoring for exposure to pesticides: Recent update
(2007)Extensive use of synthetic pesticides for agricultural and nonagricultural purposes began in the past 50 years. As a result of their wide and extensive application, exposure to hazardous pesticides is a concern to the ... -
The application of an improved method for trans-resveratrol to determine the origin of Greek red wines
(2001)A rapid and sensitive method has been developed for the determination of trans-resveratrol in wine. This method consists of a solid phase extraction step followed by a rapid HPLC quantification step (30 min). The improvement ... -
Development and application of GC-MS method for monitoring of long-term exposure to the pesticide cypermethrin
(2014)Cypermethrin (CPMN) is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as for domestic purposes. In the present study a gas chromatography-mass spectrometry (GC-MS) ... -
Development of GC-MS/MS method with programmable temperature vaporization large volume injection for monitoring of 17 beta-estradiol and 2-methoxyestradiol in plasma
(2012)Monitoring of estradiol and its metabolites in biological samples is essential for the accurate diagnosis of a number of endocrine diseases. In this study, a sensitive, precise and specific GC-MS/MS method for the ... -
Liquid chromatographic determination of fosthiazate residues in environmental samples and application of the method to a fosthiazate field dissipation study
(2005)A method was developed and validated for the determination of residues of the organophosphorus nematicide fosthiazate in soil and water by using reversed-phase liquid chromatography with UV detection. Good recoveries (> ... -
Residue screening in apple, grape and wine food samples for seven new pesticides using HPLC with UV detection. An application to trifloxystrobin dissipation in grape and wine
(2009)A new analytical procedure was developed and validated, using liquid chromatography, for simultaneous determination of seven new pesticides belonging to different chemical classes (azoles, strobilurines, benzoylureas, and ...
