Abstract
Curie point pyrolysis gas chromatography-mass spectrometry (Py-GC-MS) has been compared with classical extraction procedures (Soxhlet, sonication, KOH digestion, microwave-assisted) followed by GC-MS analysis for the determination of polycyclic aromatic hydrocarbons (PAHs) in contaminated soil. In each case, the efficiency of the technique was examined for 16 PAHs included in the US Environmental Protection Agency Priority Pollutant List. The results indicate that the recovery of PAHs is dependent on the extraction technique. The highest recoveries of PAHs were obtained with Curie point pyrolysis and KOH digestion. Py-GC-MS appeared to be interesting alternative method for the determination of PAHs in contaminated soil. The results were validated by certified soil (CRM 104) analysis.

Abstract
A simple and efficient method for the enrichment of low molecular weight polycyclic aromatic hydrocarbons (PAHs) in effluents originating from wastewater treatment plants is presented here. The proposed protocol couples the recently introduced hollow fibre liquid-phase microextraction (LPME) method with gas chromatography-mass spectrometry. Method parameters were controlled and the optimised experimental conditions were: 5 ml aqueous samples, containing 2.5% NaCl w/v, stirred at 1000 rpm, extracted with toluene for 15 min. The developed protocol yielded a linear calibration curve in the concentration range from 0.5 to 50 microg l(-1) for all target analytes (namely acenaphthene, phenanthrene, fluoranthene and pyrene) and limits of detection in the low microg l(-1) level (0.005-0.011 microg l(-1)). The repeatability and inter-day precision of the method varied between 2.7% and 11.3% and 7.9% and 14.4% respectively. The relative recoveries from different types of natural water samples revealed that matrix had a small effect on the hollow fibre LPME process. The developed method was then applied for the determination of PAHs contamination in effluent samples taken from two major municipal wastewater treatment plants. The results were compared with those obtained with solid-phase microextraction. The ability of both microextraction methods to concentrate organic analytes was demonstrated as both methods confirmed the presence of PAHs as well as of phthalates in the examined effluent samples.

Abstract
Membrane-assisted solvent extraction (MASE) in combination with large volume injection-gas chromatography-mass spectrometry (LVI-GC-MS) was applied for the determination of 16 polycyclic aromatic hydrocarbons (PAHs) in aqueous samples. The MASE conditions were optimized for achieving high enrichment of the analytes from aqueous samples, in terms of extraction conditions (shaking speed, extraction temperature and time), extraction solvent and composition (ionic strength, sample pH and presence of organic solvent). Parameters like linearity and reproducibility of the procedure were determined. The extraction efficiency was above 65% for all the analytes and the relative standard deviation (RSD) for five consecutive extractions ranged from 6 to 18%. At optimized conditions detection limits at the ng/L level were achieved. The effectiveness of the method was tested by analyzing real samples, such as river water, apple juice, red wine and milk.

Abstract
In recent years waterpipe smoking has spread worldwide and emerged as global health issue. Yet only little is known on the composition of waterpipe smoke. Here, we present a study on the identification and quantification of primary aromatic amines (PAAs) in this complex environmental matrix. Smoking of the waterpipe was conducted with a smoking machine and particulate matter was collected on glass fiber pads. We developed a fast, simple and specific liquid chromatography-electrospray ionization tandem mass spectrometry (LC-MS/MS) approach to simultaneously detect 31 different PAAs in this matrix. The detection limits comprised a range of 0.45-4.50 ng per smoking session, represented by 2-aminobiphenyl and 3,4,5-trichloroaniline, respectively. Intra- and inter-day precision were determined and proved excellent. We detected 31.3 ± 2.2 ng aniline and 28.0 ± 1.6 ng 4,4'-oxydianiline in the smoke of one waterpipe session. The water in the bowl exerted a small but considerable filter effect on PAAs. The method worked-out showed excellent sensitivity and specificity and is thus highly suited for the determination of PAAs in mainstream waterpipe smoke.

Abstract
BACKGROUND/AIMS: Epidemiological studies suggest that there is a considerable overlap between functional dyspepsia (FD) and irritable bowel syndrome (IBS). The aim of this study was to examine concurrent gastrointestinal symptoms in FD and IBS. METHODS: A total of 186 college students filled out a questionnaire regarding whether they had uninvestigated dyspepsia (UD, FD without endoscopic examination) and IBS based on Rome-II criteria. Gastrointestinal symptoms were measured using the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. RESULTS: A total of 181 students (98 males, mean age 24.6 years) completed both questionnaires. The prevalence of UD, IBS, and UD+IBS overlap was 12 (6.7%), 40 (22.1%), and 8 (4.4%), respectively. A significant UD+IBS overlap was observed (66.7% IBS in UD, 20.0% UD in IBS). Reflux scores of GSRS in either UD or IBS were significantly greater than in those without. Gastroesophageal reflux disease (GERD), defined as weekly occurring moderate symptoms of heartburn and/or acid regurgitation and evaluated using the GSRS, was found in 16 (8.8%) of the subjects. The prevalence of IBS was significantly higher in GERD patients than in non-GERD patients (50.0% vs 19.4%). CONCLUSIONS: The considerable overlap not only between UD and IBS, but also between GERD and IBS, suggests the involvement of common pathophysiological disturbances in the two conditions.

Abstract
OBJECTIVE: To investigate tobacco-related knowledge, attitudes and analyze related factors among the college students in Guangzhou. METHODS: In May 2012, 11 593 college students from six universities in Guangzhou were selected and investigated by stratified cluster random sampling.Investigation content includes social demographic information, smoking behaviors, tobacco-related knowledge and attitudes. Chi-square test was used to analyze the difference about knowledge of harm of tobacco and awareness of tobacco control related legislation as well as tobacco-related attitudes between smokers and non-smokers. Factors on tobacco-related knowledge were analyzed by using rank sum test. RESULTS: Current smoking rate among undergraduates was 6.1% (706/11 593) , 11.5% (622/5388) for males and 1.4% (84/6205) for females. The awareness rate of that smoking addiction was a chronic disease in non-smokers(82.6%, 8954/10 836) was higher than that in smokers (73.1%, 509/696) (chi(2) = 40.09, P

Abstract
In order to study the pollution status and the seasonal and diurnal variations, ambient concentrations of BTEX were analyzed at Beijing from 2008-10 to 2009-10, by using the method of two-step-concentration-gas spectrometry/mass (CCD-GC/MS). The average concentration of BTEX in Beijing was 13.9-44.0 microg x cm(-3). The dominant compound components were toluene, benzene, followed by ethyl benzene, m/p-xylene, o-xylene. Compared with foreign cities and regions, the level of BTEX at Beijing atmosphere was relatively lower. The study found that BTEX in Beijing mainly came from vehicle emissions, coal and solvent evaporation were also important sources of BTEX. No significantly obvious seasonal variation was observed, with the highest concentrations observed in spring and summer and the lowest concentrations generally found in autumn. Seasonal variations of emission sources were the main reason for seasonal changes of BTEX. However, the impact of weather factors on the BTEX can not be ignored, such as temperature and strong winds. Significant diurnal variations in BTEX were observed. The BTEX concentrations displayed a bimodal pattern, with peak between 08:00 and 10:00. and between 16:00 and 08:00. The minimum concentration generally appeared around 14:00.

Abstract
The waterpipe is an ancient Middle Eastern tobacco delivery system, which is also known as hookah, shisha, or narghile, and it is gaining widespread use. Waterpipes are often perceived as less dangerous than cigarettes. The amount of smoke inhaled in a waterpipe session may equal that produced by more than 100 cigarettes with high nicotine, carbon monoxide, and carcinogen intake. A case of significantly elevated intraoperative carboxyhemoglobin level and decreased oxyhemoglobin saturation in a patient with recent waterpipe use is presented.

Abstract
A new unbreakable solid phase microextraction (SPME) fiber coating based on aniline-silica nanocomposite was electrodeposited on a stainless steel wire. The electropolymerization process was carried out at a constant deposition potential, applied to the corresponding aqueous electrolyte containing aniline and silica nanoparticles. The scanning electron microscopy (SEM) images showed the non-smooth and the porous surface structure of the prepared nanocomposite. The applicability of the new fiber coating was examined by headspace-solid phase microextraction (HS-SPME) of some environmentally important polycyclic aromatic hydrocarbons (PAHs), as model compounds, from aqueous samples. Subsequently, the extracted analytes were transferred into a gas chromatography (GC) by thermal desorption. Parameters affecting the synthesizing and extraction processes including the voltage of power supply, the weight ratio of components, the time of electrodeposition, extraction time and temperature, the ionic strength, and desorption temperature and time were optimized. Eventually, the developed method was validated by gas chromatography-mass spectrometry (GC-MS). At the optimum conditions, the relative standard deviation (%RSD) values for a double distilled water spiked with the selected PAHs at 40 ng L(-1) were 6-13% (n=3) while the limit of detection (LOD) results were between 1 and 3 ng L(-1). The calibration graphs were linear in the concentration range from 20 to 4000 ng L(-1) (R(2)>0.995). Finally the developed method was applied to the analysis of Kalan dam, rain and tap water samples and the relative recovery values were found to be in the range of 76-109%, under optimized conditions. In addition, the synthesis of the nanocomposite coating was carried out conveniently while it is rather inexpensive, easy, simple, rapid and highly durable and can be used frequently.
