“…Studies have been focused on fabricating low cost, simple, robust and long-life fiber for the target analytes. A variety of methods for the production of fibers have been developed such as sol-gel, and physical and electrochemical polymerization (Korba et al, 2013). Sol-gel technology can provide efficient incorporation of organic components into the polymeric structures in solution under the relatively mild conditions.…”

“…Moreover, the sol-gel coating technique provides a porous structure, which increases the surface area of the fiber and affords a fast mass transfer rate in the film (Saraji et al, 2013). PPy fiber for HS-SPME was fabricated by electrochemical polymerization onto a steel wire and in-situ produced fiber coating was proven to have high extraction efficiency for endocrine disruptor pesticides (Korba et al, 2013). Even after 250 usages, the fiber can still be used sensitively with a reasonable precision.…”

“…Stainless steel wire as a supporting substrate in combination with sol-gel technology was shown flexible, unbreakable, with higher mechanical strength than silica fiber (Saraji et al, 2013). Stainless steel wire was also used as a support for dodecyl sulphate-doped polypyrrole (Ppy-DS) coating (Korba et al, 2013) and for PDMS coating (Bagheri et al, 2012). Majority of published papers in the field of pesticide residue analysis in food samples were performed using commercially available fibers such as PDMS, PDMS-DVB (Table 1, 2).…”

“…Extraction of OPPs in water and vegetable samples using fiber coated with polypyrole/sol gel composite was performed in DI mode (Saraji et al, 2013). HS mode was used for extraction of organochlorine pesticides in wine using dodecylsulfate-doped polypyrole (Ppy-DS) fiber (Korba et al, 2013). Selection of operating in HS or in DI mode depends on the volatility of the analytes and the matrix characteristics (Martins et al, 2013).…”

“…Low stirring rate (250 rpm) can be used in DI provided that the signal for pesticides was decreased at higher stirring rate (Filho et al, 2008). The most frequently used stirring rate for HS mode was 600 rpm (Rodrigues et al, 2011;Korba et al, 2013;Wang et al, 2013), nevertheless some studies were performed using lower (120 rpm) (Ibrahim et al, 2010) or higher stirring rate (800 rpm) (Chai et al, 2009). For HS mode stirring rate 600 rpm was used for determination of OCPs pesticides in radish (Dong et al, 2005).…”

Abstract:The current trend in sample preparation methods is devoted to minimizing or eliminating the volume of extractive solvent. In this review, the focus on solid phase microextraction (SPME) as a solvent free sample preparation method for the isolation of pesticides residues in different food matrices is given. To achieve satisfactory extraction efficiency, selection of the fiber coating is an important step in the method development. Here, recent trends in new supporting materials and new fiber coatings development are discussed. Finally, applicability of SPME for the pesticide residues analysis in various food matrices using mainly chromatographic methods is also reviewed.

This article presents an overview of analytical methods for the analysis of pesticide (new‐generation) and related compounds in the last 5 years, which updates the previous one. Pesticides included in this group display almost no change, but the evolution of analytical techniques is important. In general, new pesticides are now included in multiresidue methods with generic sample treatment methodologies being able to extract as many pesticide classes as possible. However, this article focuses not only on these common multiresidue methods but also on specific methodologies as single‐residue methods for the analysis of new‐generation pesticides. The most widely used detection technique for the determination of pesticides is mass spectrometry (MS) combined with gas chromatography (GC) and/or liquid chromatography (LC). However, the advances in immunoassays, biosensors and other techniques are also included. Finally, the future perspectives and the trends for pesticide residue analysis in food and environmental matrices are outlined.

An effective, rapid, green and simple method for the preconcentration and determination of endocrine disruptor pesticides (aldrin, bromopropylate, penconazole, chlorpyrifos, iprodione, lambda-cyhalothrin, and procymidone) has been developed by using solidified floating organic drop microextraction. In this technique a free microdrop of 2-dodecanol which is liquid at the room temperature was used as an extracting solvent. Considering the number of parameters that are likely to affect the signal, extraction solvent type, extraction solvent volume, extraction time and temperature, sample volume, salt effect and rate of mixing on pesticides extraction were optimized. The analytes were extracted from the water samples by using 10 mL of 2-dodecanol for 20 min at 70°C in the presence of 0.5 g/10 mL NaCl. The separation power of the GC was coupled with the excellent sensitivity of the microextraction technique enabling us to determine the pesticide mixtures simultaneously in the ng/L range with satisfactory relative standard deviation values. The limit of detection levels attained by this method for Iprodione and Procymidone in particular, clearly display the effectiveness and sensitivity of the method over previous methods which include time consuming steps and require high volumes of sample. The developed method was validated for the monitoring of endocrine disruptor pesticides in well water samples.
