“…However, the recovery rates are low, especially for lipophilic compounds present in various matrices containing large amounts of lipids and/or proteins, such as whole blood and tissue homogenates. 18,19 This is probably the reason why most of the previous studies [4][5][6][7][8][9][10][11][12] on the analysis of polycyclic aromatic hydrocarbons or volatile organic compounds including naphthalene and/or p-dichlorobenzene did not deal with whole blood samples. However, in postmortem forensic toxicological analysis, hemolyzed whole blood should be frequently analyzed.…”

“…There have been many reports on the analysis of polycyclic aromatic hydrocarbons or volatile organic compounds including naphthalene and/or p-dichlorobenzene in water, soil and plant samples, [4][5][6][7][8] in workers' urine, 9-11 and workers' plasma 5,12 by gas chromatography-mass spectrometry (GC-MS). However, most of the above reports have dealt with screening tests for many compounds from a viewpoint of environmented chemistry.…”

“…For example, Safarova et al [8] used headspace analysis combined with gas chromatography mass spectrometry for the analysis of 53 volatile organic compounds in river waters, waste waters and treated water samples down to 0.1 µg.L −1 concentration levels. They concluded that the content of VOCs in river water mainly correlates to the content of these compounds in waste waters, which shows the anthropogenic character of the pollutions.…”

“…Static or dynamic headspace gas chromatography (GC) analysis is the most adopted methods used by environmental agencies to determine VOCs from solid and liquid matrices [13]. However, direct aqueous injection (DAI) [14], liquid-liquid extraction (LLE) [14], membrane techniques, solid-phase extraction (SPE), solid-phase micro extraction (SPME) [8,15] and distillation techniques are also used as sample preparation techniques in analysis of VOCs. A primary benefit of using headspace GC is that one can analyze small amounts of analytes buried in a large amount of matrix without having to inject the matrix into the chromatography column.…”

Static headspace coupled with gas chromatography-mass spectrometry was applied to extraction and analysis of volatile organic compounds in water samples. The effects of various factors affecting on the extraction efficiency including: the extraction temperature, extraction time, salt concentration and stirring speed were carried out by means of a 2 4 full factorial design. It was found that the effects of extraction temperature and salt concentration were significant. Then, a central composite design was performed to optimize the level of these factors. The optimal headspace conditions were achieved when the vials were heated under 88°C and 29% w/w addition of salt. At optimum operating conditions, analytical figures of merit of method such as linearity (0.9962-0.9996), repeatability (1.2-12.13%), detection limits (0.1-4.9 μg.L −1 ) and linearity dynamic range (10-1000 μg.L −1 ) were determined. The proposed methods can be used to direct investigation of the presence of Volatile organic compounds in environmental samples without pre-treatment of samples. Finally the optimized method was used to investigate the existence of volatile organic compounds in Babolroud River in the north of Iran.

Original PaperFullerenes as sorbent materials for benzene, toluene, ethylbenzene, and xylene isomers preconcentration A simple and novel SPE system for benzene, toluene, ethylbenzene, and xylene isomers (BTEX) compounds in water is proposed in which samples are directly propelled from a 15 mL glass vial through a sorbent column by means of a needle, thereby avoiding evaporative losses and the sorption of BTEX on the manifold materials. Following elution with 150 lL of ethyl acetate, 1 lL of extract is injected into a gas chromatograph -mass spectrometer system. A comparative study of various sorbent materials (C 60 fullerene, Tenax TA, and RP-C 18 ) revealed C 60 fullerene to be the best choice in terms of sensitivity (a likely result of its increased sample breakthrough volume), precision (the surfactant medium used to prepare samples minimizes evaporative losses), selectivity (C 60 fullerene only interacts with nonpolar aromatic compounds), and reusability (columns containing 60 mg of C 60 fullerene remain serviceable for at least 6 months). This C 60 fullerene-based method exhibits a linear range of 0.1 -100 lg/L, a detection limit of 0.04 lg/L, and an RSD of ca. 3%. It was applied to the determination of BTEX in various types of water including sea and waste water with good precision.
