Optimization of headspace solid-phase microextraction for the determination of pesticide residues in vegetables and fruits.
A headspace solid-phase microextraction method has been developed for the determination of 8 pesticides in vegetables and fruits by using gas chromatography with an electron capture detector. Two types of fibers (polyacrylate, 85 microm and polydimethylsiloxane, 100 microm) have been assayed and compared. The main factors: extraction and desorption parameters, ionic strength, and the effects of...
متن کاملApplications of solid-phase microextraction for the analysis of pesticide residues in fruits and vegetables: a review.
This paper reviews the application of various modes of solid-phase microextraction (SPME) for the analysis of pesticide residues in fruits and vegetables. SPME is a simple extraction technique that eliminates the use of solvent, and it is applied for the analysis of both volatile and nonvolatile pesticides. SPME has been successfully coupled to both GC and LC. The coupling with GC has been stra...
متن کاملHeadspace Solid Phase Microextraction in Pesticide Residues Analysis: 1. Optimisation of Extraction Conditions
The method of headspace solid phase microextraction (HS/SPME) was successfully used in a simultaneous multicomponent analysis of hexachlorobenzene (HCB), tefluthrin, heptachlor, aldrin, chlorpyrifos, fenthion and bifenthrin in aqueous medium. Measurements were performed using a nonpolar polydimethyl siloxane (PDMS) fiber. Detection and quantification were done by gas chromatography/mass spectro...
متن کاملPesticide Residues in Fruits and Vegetables
The aim of this chapter is to describe the presence of pesticide residues in fruits and vegetables, mainly how they are introduced, dissipated, degraded, affected by food processing techniques and their risk assessment. Fruits and vegetables are important components of the human diet since they provide essential nutrients that are required for most of the reactions occurring in the body. A high...
متن کاملPesticide Residues in Fruits and Vegetables
Detecting and quantifying pesticide residues in fruits and vegetables is a crucial public health function for analytical laboratories throughout the world. Professor Amadeo Fernàndez-Alba, a full professor in Analytical Chemistry at the University of Almeria, Spain, has headed the European Reference Laboratory for Pesticide Residues in Fruits and Vegetables (EURL-FV) since 2006. Professor Fernà...
