“…The results were both reproducible and comparable to conventional tedious methodologies. Apart from C r silica based columns a number of other fat retainers have been studied as discussed below (26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39).…”

“…Neutral alumina has also been used for the extraction of organochlorine pesticides (OCPs) from chicken fat (30), OCPs and PCBs from human adipose tissue (57), and PCBs from fish (32). In only one of these studies was it possible to estimate FFR values (32), which were somewhere between 0.040 and 0.066.…”

“…Silica was successfully utilized in the extraction of OCPs from chicken fat and lard (30). Later Alley and Lu investigated six different fat retainers and found that Florisil adequately separated spiked PCBs from bulk lipids in chicken egg and fish (33).…”

This chapter describes the utilization of recent extraction techniques such as supercritical fluid extraction, pressurized liquid extraction and microwave-assisted extraction for the determination of persistent organic pollutants in food and feed samples. These techniques have been developed because the extraction step can severely limit the entire analytical procedure. Several food crises, for example dioxins entering the food chain, have stressed the requirement for high sample throughput. Increased sample throughput can be obtained by using automated clean-up systems following the extraction process; however, these techniques are often very costly. This text aims at describing how a substantial decrease in the time spent on sample handling can be achieved with for example integrated clean-up strategies. 126

“…It has been developed for the extraction of pesticides from different kinds of samples followed by a cleanup technique to purify the extracted analytes for their further analysis by gas chromatography (Motohashi et al, 2000, Lang et al, 2001, Poustka et al 2003. The US Department of Agriculture's Food Physical Chemistry has investigated the direct use of supercritical fluid as a technique for the clean up of organochlorine pesticides from greasy samples (France et al, 1991), but to the knowledge of the authors, no studies have been performed on the direct extraction of a mixture of organophosphorous and synthetic pyrethroids pesticides.…”

RESUMENExtracción con fluidos supercríticos como método de limpieza para la extracción de pesticidas de la cera de lana cruda. Un estudio preliminar.Este trabajo es un estudio preliminar para el desarrollo de un método de extracción de pesticidas directamente de las muestras de cera mediante extracción con fluido supercrítico. La novedad del estudio consiste en la extracción directa de los pesticidas de la cera de lana cruda sin ninguna limpieza previa, cuando muchos autores han considerado casi imposible la extracción directa. PALABRAS-CLAVE: Cera de lana -Dióxido de carbono -Extracción con fluido supercrítico -Pesticidas organofosforados -Pesticidas piretroides sintéticos. SUMMARY Supercritical fluid extraction as a clean-up method for the extraction of pesticides from wool wax. A preliminary approach.The work presented is a preliminary study for the development of a method for the extraction of pesticides from wax samples by means of superficial fluid extraction. The novelty of the study is the direct extraction of the pesticides from raw wool wax without any cleanup, as direct extraction has been considered almost impossible by many authors.
