Color design of cigarette packaging for reducing smoking rate in youth

Since smokers are becoming younger and younger, it is necessary to curb the tobacco epidemic at a younger age to prevent the devastating damage caused by tobacco products to future generations. This study focuses on the color schemes of cigarette packaging. It aims to find out color schemes of teenage consumers' disgust and apply them to cigarette packaging, which ultimately reduces the desire of purchasing and the smoking rate of young people. First, there were two ways to acquire color schemes. One was to extract the color schemes that can make teenagers disgust and keep them away from cigarette by association of psychological adjectives. The other way was to match achromatic colors with the chromatic colors that teenagers dislike in the questionnaire of 126 colors. Finally, eye movement experiment was used to verify the acquired color schemes meet the expected objectives of this study. A new idea to reduce the smoking rate of teenagers was proposed, and a method for the color design of cigarette packaging was provided.     

Measurement of chemical emission rates from cigarette butts into air

This study examined airborne emissions from cigarette butts for styrene, 2-methyl-2-cyclopenten-1-one, naphthalene, triacetin, and nicotine. Ten experiments were conducted by placing butts in a stainless steel chamber and measuring the chemical concentrations in chamber air. Emission rates were determined from the concentrations. Triacetin and nicotine concentrations were roughly 50% of initial concentrations after 100 hours, while concentrations of other chemicals decayed to less than 10% of initial concentrations within 24 hours. Initial emission rates per cigarette butt ranged from 200 to 3500 ng h⁻¹. Triacetin and nicotine emission rates at 25°C were 1.6 to 2.2 times higher than the rates at 20°C, while the emission rates of other chemicals at 25°C were 1.1 to 1.3 times higher than the rates at 20°C only during the first sampling period. The chemical concentrations and emission rates at 30°C were comparable or lower than the values at 25°C, possibly due to different batches of cigarettes used. The 24-hours emitted mass of nicotine from a cigarette butt at 25°C could be up to 14% of the literature reported nicotine masses emitted from a burning cigarette.

益母草多糖微波提取及在卷烟中的应用

采用微波辅助法对益母草多糖的提取工艺进行考察,并对益母草多糖进行了卷烟加香试验。以干燥益母草原料粒度（目数）、料液比、微波功率、提取时间为考察因素,益母草多糖得率为指标,采用单因素和正交试验法对益母草多糖提取工艺进行优化。确定了微波辅助提取的最佳工艺参数为：粒度（目数）80目（粒径约0.178 mm）,料液比1∶50（g/mL）,微波功率700 W,提取时间16min。按此优化条件,益母草多糖得率可达到3.20%。加香应用结果表明,益母草多糖能赋予卷烟特殊香韵调,保润并柔和细腻烟气,提高烟气舒适性。     

烟草味电子烟油中挥发性成分分析

采用二氯甲烷对3家公司的5种电子烟油样品进行萃取,并用气-质联用（GC-MS）法鉴定。通过对NIST 11谱库的检索,对5种样品中挥发性成分进行了比较分析。结果表明5种样品中的挥发性成分差别较大,共鉴定出40种挥发性成分,依据作用或来源分为雾化剂、烟叶提取物和薄荷提取物三类。其中相对含量水平较高且在5种样品中都检出的成分是丙二醇、烟碱和甘油。3家公司的5种烟草味电子烟油在抽吸品质上有所差异,C公司样品在抽吸感官感受上相较其他两家公司样品具有明显优势,其中样品C1又略好于C2。比较发现,C公司电子烟油的挥发性成分中含特有的8种多甘醇类化合物,可能是这些物质的协同作用而改善了抽吸品质。     

超临界CO_2流体萃取糊毛烟净油成分分析及其对卷烟感官质量的影响研究

利用超临界CO2流体萃取技术萃取糊毛烟叶制备糊毛烟净油,所得净油为红褐色澄清透亮的溶液,得率为5%。净油经GC-MS分析鉴定,其中含有大量的烟草特征致香化合物如茄酮、麦斯明、香叶基丙酮、β-紫罗兰酮、2,3-联吡啶、巨豆三烯酮、六氢法尼醇、植酮、新植二烯、法尼基丙酮等,和异戊酸、乳酸、己酸、乙酰丙酸、苯甲酸、苯乙酸、十二酸、十四酸、十六酸等有机酸。卷烟加香评吸结果表明该净油能提升烟草本身香气,增加特征烟香,使烟气质地细腻柔和,抑制刺激性,掩盖杂气,并能赋予卷烟独特的风格特征,可明显提升卷烟的抽吸品质,是一种理想的高品质烟用香料。

Environmental and individual exposure to secondhand aerosol of electronic cigarettes in confined spaces: Results from the TackSHS Project†

Secondhand electronic cigarette (e-cigarette) aerosol (SHA) might impair indoor air quality and expose bystanders. This study aims to investigate exposure to SHA in controlled conditions of enclosed settings simulating real-world scenario. An experiment was performed in a car and in a room, in which SHA was generated during a 30-minute ad libitum use of an e-cigarette. The experiment was replicated on five consecutive days in each setting. We measured PM_2.5, airborne nicotine concentrations, and biomarkers of exposure to SHA, such as nicotine metabolites, tobacco-specific nitrosamines, propylene glycol, and glycerol in bystanders’ saliva samples before, during, and after the exposure period. Self-reported health symptoms related to exposure to SHA were also recorded. The results showed that the highest median PM_2.5 concentration was recorded during the exposure period, being 21 µg/m³ in the room setting and 16 µg/m³ in the car setting—about twofold increase compared to the baseline. Most concentrations of the airborne nicotine and all biomarkers were below the limit of quantification in both settings. Bystanders in both settings experienced some short-term irritation symptoms, expressed as dry throat, nose, eyes, and phlegm. In conclusion, short-term use of an e-cigarette in confined spaces increased indoor PM_2.5 level and caused some irritation symptoms in bystanders.     

Development of α-Tocopherol Acetate Nanoparticles: Influence of Preparative Processes

We studied different methods of preparing α-tocopherol acetate (ATA) nanoparticles, which are to be used in targeting the lungs as aerosols in order to prevent cigarette smoke toxicity. Poly-(lactide) nanoparticles were prepared using nanoprecipitation and solvent evaporation techniques, which produced, respectively, too small and too large nanoparticles to be aerosolized. The emulsification-diffusion method produced 2 months stable nanoparticles with a size between (500–700 nm). Increasing ATA concentration (1–7 mg/mL) induced a decrease in the association rate (97–93%) and in the adsorbed ATA rate (7–4.5%), which was associated with variations of Zeta potentials (?27.5 to ?24.3 mV) and decrease in polymeric wall thickness and density.
