The aim of this work was the evaluation QuEChERS extraction method for polycyclic aromatic hydrocarbon (PAH) determination in various types tea. In experiment, different kinds solvents, sorbents and a final sample preparation were compared. extracts analysed by gas chromatography-selected ion monitoring-mass spectrometry. results suggest that acetonitrile extraction, clean up with SAX liquid–liquid best combination giving most purified acceptable compound recoveries teas. study real samples,...

The aim of this study was to evaluate the application quick, easy, cheap, effective, rugged and safe method for simultaneous determination polycyclic aromatic hydrocarbons pesticide residues in fresh herbs. In experiment two extraction solvents standard types sorbents were used. extracts analyzed using GC-SIM-MS. results suggest that acetonitrile is more suitable solvent giving purified samples better recovery values (71.6 %-116.9 %) with RSD lower than 15 % most compounds. real pesticides...

This paper reports the evaluation of Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method for determination polycyclic aromatic hydrocarbons (PAHs) in food animal origin with GC–MS detection. Although available literature, there is a lot information about sample preparation PAHs samples, but QuEChERS application has not been reported as yet. The results showed that best recovery ratios 72.4–110.8 % relative standard deviation lower than 10 all determined compounds were received...

Per- and polyfluoroalkyl substances (PFAS) belong to the emerging class of persistent organohalogenated contaminants in environment. We determined levels 10 PFAS selected samples representing different food types, with a special focus on those rich protein such as fish, meat preparations, liver, eggs, leguminous vegetables. Such determinations were based Quick Easy Cheap Effective Rugged Safe extraction procedure followed by micro-high-performance liquid chromatography-tandem mass...

Fruit and vegetables play a major role in human nutrition due to richness of nutrients, dietary fibre, phytochemicals. As intake is identified as one the dominant exposure pathways perfluoroalkyl substances (PFASs), cross-sectional study involving determination their levels food plant origin has been conducted. Locally-grown imported fruit vegetable samples, collected 2016 were inspected for 10 acids (PFAAs) using QuEChERS sample pre-treatment procedure followed by micro-HPLC-MS/MS. Three...

Bee products, including bee pollen (BP) and bread (BB) are natural sources that contain a diverse range of bioactive compounds. The objective this study was to investigate the potential BP BB enhance functional properties shortcrust pastry cookies. impact on colour parameters, polyphenolic compounds content, heat-induced content (acrylamide, furfural, 5-hydroxymethylfurfural (HMF)), antioxidant properties, inhibitory effects against advanced glycation end products (AGEs) formation...

The purpose of this study was to evaluate the application dispersive solid-phase extraction with use primary secondary amine (PSA), NH2 and strong anion exchange (SAX) sorbents for polycyclic aromatic hydrocarbon (PAH) determination in samples coffee. final extracts were analysed by gas chromatography selected ion monitoring mass spectroscopy (GC-SIM-MS). results indicated that cleanup PSA SAX followed solvent from acetonitrile hexane (liquid–liquid extraction, LLE) best variant method,...

Perfluorinated compounds, including perfluorinated acids and sulfonates, are environmentally persistent. These compounds commonly used in consumer products as stain/water/grease repellents carpets clothing, cooking utensils nonstick coating food contact materials a coating. This paper explores the potential application of liquid chromatography coupled with tandem mass spectrometry (LC‐MS/MS) system for measurement selected sulfonates three different brands (A, B C) materials, wrapping...

Chemical Nature of PFCsPerfluorinated compounds (PFCs) are a group organofluorine compounds, aliphatic hydrocarbons, in which all or almost hydrogen atoms replaced with fluorine.They consist hydrophobic alkyl chain varying length (typically C4 to C16), and hydrophilic end group, X.The part may be fully partially fluorinated.Their general structure is given Fig. 1.The X, can neutral, positively negatively charged.The resulting non-ionic, cationic, anionic surface active agents due their...

The paper reports the levels of thermal processing contaminants such as polycyclic aromatic hydrocarbons (PAHs), 3-monochloropropane-1,2-diol (3-MCPD) and acrylamide (AA) in 28 dried (raisins, dates, apricots, cranberries plums—prunes) 15 smoked (pears, apples plums) fruit samples from Polish retail market. Analytes were determined using GC–SIM–MS, after being subjected to modified QuEChERS method. results showed that almost all PAHs detected samples, except dibenzo(a,h)anthracene, which was...

This study aims to determine the effect of raw potato tubers’ exposure UV-C radiation and semi-products soaking in water on content acrylamide dry matter French fries. The fries were prepared from tubers Innovator variety (Solanum tuberosum L.). Acrylamide contents determined by HPLC-UV/Vis a C-18 column after extraction fried potatoes with acetonitrile. Potato caused an increase decrease

Abstract Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are of increased concern because their bioaccumulation in humans the biota, health risk they pose to other animals, persistence environment. In present study, occurrence PFAS selected tissues from pike ( Esox lucius L.) roach Rutilus rutilus collected two lakes Masurian Lake District (Poland) eastern Europe was addressed. Ten were analyzed tissue brain, liver, kidneys, gonads, muscles by micro‐high‐performance liquid...

Honey is consumed worldwide because of its nutritional, therapeutic and medicinal properties. Generally, honey should reach the consumer in a pure form, but it often contaminated various ways. Thus, this study was designed to check for presence pesticide residues, polycyclic aromatic hydrocarbon (PAH) levels, content 5-hydroxymethylfurfural (HMF) selected European honeys (26 samples) obtained from shops. The most frequently detected organochlorine (OCPs) 4,4'-DDD, which found fourteen...
