Results: The average age of starting cigarette and water pipe smoking was 14.5 Â± 2.4 and 11.2 Â± 1.5 years, respectively. The first experience with water pipe occurred mostly in the traditional teahouses for girls (54.8 %), and in family parties (48.2 %) for boys. In both genders, the first place of cigarette smoking was at friends' parties (56.8 % for boys, and 52.1 % for girls) and then followed by traditional teahouses (43.2 % for boys, and 47.9 % for girls). The most common reasons youths have picked up cigarette smoking were mainly to attract attention from friends, family inattention and poverty. Meanwhile, nearly all water pipe smokers reported using it for fun. The strongest predictors of smoking among boys were respectively father's occupation, having a smoking mother, and the number of smoking peers, whereas among girls, these factors were respectively having a smoking mother, frequenting traditional teahouses, and the number of smoking peers. Lower education of fathers and divorce among parents increased the probability of smoking in both genders, especially girls. School/ work failure, as well as troubled relationship with parents and siblings were the other significant predictors of smoking in both genders, notably in girls. Conclusion: Public health control measures should be adopted not only to curtail cigarette use, but also to address water-pipe use. Preventive measures should be regarded as a high priority for socio-economically disadvantaged families. Â© BirkhÃ¤user Verlag, Basel 2007.

OBJECTIVE: To identify the prevalence of waterpipe use among Iranian university students and to explore perceived reasons for use. METHODS: A random sample of 1024 university students at two major universities in South Iran was enrolled in the study. A three-part questionnaire (baseline data, tobacco smoking status and perceived reasons for waterpipe use) was used. Students filled out the self-administered questionnaire in their classrooms. RESULTS: The prevalence of waterpipe smoking in the respondents' lifetime and in the last 30 days was 42.5% and 18.7%, respectively. The mean age at initiation of waterpipe smoking was 16.3 +/- 3.2 years. Ever smoking was positively associated with age and male sex, whereas no association was found regarding marital status. The highest odds of lifetime waterpipe smoking were observed in students with close friends who smoked the waterpipe (5.94, 95%CI 4.26-8.30). The most important perceived reason for waterpipe smoking as stated by students was enjoyment (55.8%). CONCLUSION: Given the alarming prevalence of waterpipe smoking, preventive measures should be adopted among university students taking into account the influence of peers, siblings and parents in the lessening social tolerance of waterpipe smoking.

Based on the strong van der Waals interaction present in GO and abundant oxygenous groups in GO sheets, a simple layer-by-layer self-assembly method was used in the preparation process and then C18 was successfully self-assembled on GO via C-O-Si bonding. Coupled with gas chromatography, extraction performance of the fiber was tested with polycyclic aromatic hydrocarbons (PAHs) as model analytes. The fiber not only exhibited excellent extraction efficiency and selectivity, but also showed many advantages including high rigidity, long service life and well stability toward organic solvent, acidic and alkali solutions, and high temperature. The relative standard deviations for single-fiber repeatability and fiber-to-fiber reproducibility were less than 7.26 and 17.25%, respectively. The detection limits to the PAHs were less than 0.08 mug L(-1) and the calibration curves were linear in a wide range for all analytes. The as-established Solid-phase microextraction GC method was also successfully used for determination of PAHs in two real water samples.

The synthetic strategy was verified by infrared (IR) spectroscopy and field emission scanning electron microscopy. Adsorption factors (pH, ionic strength, stirring rate, adsorption time and temperature) and desorption factors (time and temperature) of the fibers were systematically investigated. Detection limits to seven phenols were less than 0.05 microg L(-1), and their calibration curves were all linear (R(2)> or =0.9984) in the range from 0.05 to 5000 microg L(-1). This method was then utilized to analyze two real water samples from Yellow River and sanitary wastewater, resulting in satisfactory results. Compared with normal solid phase materials, this MWCNTs-bonded fused-silica fibers showed a number of advantages: wide linear range and low detection limit for extracting phenols couple with GC, and good stability in acid, alkali, organic solvents and at high temperature.

By a combination of field emission scanning electron microscope and X-ray photoelectron spectroscope studies, it is shown that perpendicularly orientated and well-aligned TiO(2) nanotubes are grown in situ on the Ti wire substrate. The SPME fiber coupled with gas chromatograph (GC) is then used to extract polycyclic aromatic hydrocarbons (PAHs), anilines, phenols, and alkanes from standard and real water samples, and exhibits high selectivity for PAHs. After the optimization of adsorption factors (pH, ionic strength, time and temperature) and desorption factors (time and temperature) of the SPME fiber for PAHs, the limit of detection (LOD) of less than 0.1 microg L(-1) is achieved, and the calibration curves are all linear (R(2)> or =0.9898) in the range from 0.1 to 1000 microg L(-1). Beyond that, the SPME fiber has high strength, large surface area, good stability at high temperature and in acid and alkali solutions, and long service life, making it have strong application potentials in the selective extraction of PAHs from complex samples at trace levels.

The MWCNTs was firstly functionalized with amine-terminated IL (MWCNT@IL) through chemical reduction, and then was doped in PANI during the electropolymerization of aniline. The resulting coating was characterized by infrared spectroscopy, field emission scanning electron microscopy and thermo gravimetry. It showed net-like structure and had high thermal stability (up to 330 degrees C). Furthermore, it presented high selectivity for the four benzoic acid esters and thus suited for their HS-SPME-GC determination. Results showed that under optimized extraction conditions, the detection limits were less than 6.1ngL(-1) (S/N=3) and the linear detection ranges were 0.012-50mugL(-1) (R>/=0.9957) for these analytes. The relative standard deviations (RSDs) were lower than 6.4% for five successive measurements with one fiber, and the RSDs for fiber-to-fiber were 4.4-9.6% (n=5). The developed method was successfully applied to the determination of these benzoic acid esters in perfume samples.

The preparation reproducibility of the PDMS/MOFs-coated stir bar was good, with relative standard deviations (RSDs) ranging from 4.8% to 14.9% (n=7) within one batch and from 6.2% to 16.9% (n=6) among different batches. Based on this fact, a new method of PDMS/MOFs-coated stir bar sorptive extraction (SBSE) and ultrasonic-assisted liquid desorption (UALD) coupled with high performance liquid chromatography-fluorescence detection (HPLC-FLD) was developed for the determination of polycyclic aromatic hydrocarbons (PAHs) in environmental water samples. To obtain the best extraction performance for PAHs, several parameters affecting SBSE, such as extraction time, stirring rate, and extraction temperature, were investigated. Under optimal experimental conditions, wide linear ranges and good RSDs (n=7) were obtained. With enrichment factors (EFs) of 16.1- to 88.9-fold (theoretical EF, 142-fold), the limits of detection (LODs, S/N=3) of the developed method for the target PAHs were found to be in the range of 0.05-2.94 ng/L. The developed method was successfully applied to the analysis of PAHs in Yangtze River and East Lake water samples.

In this study, BNNTs fixed on a stainless steel fiber by a sol-gel technique were used as sorbent for solid-phase microextraction. Five polycyclic aromatic hydrocarbons with different numbers of aromatic rings were selected as target analysts. Gas chromatography coupled with tandem mass spectrometry was used for detection and quantitative determination. Under optimized conditions, the experimental results show a wide range of linearity (1 to 1,000 ng L(-1)), less than 10.1 % repeatability of relative standard deviation, and low detection limits (0.08 to 0.39 ng L(-1)). In addition, the fabricated fiber offered good thermal and chemical stability. The proposed method was successfully applied for the analysis of real water samples, and satisfactory results were obtained with relative recoveries ranging from 80.2 to 116.8 %. The results demonstrated that BNNTs could be used as sorbent for the analysis of environmental pollutants at trace levels.
