Professor, Dept.of Mechanical Engineering, Bharati Vidyapeeth College of Engineering, Navi Mumbai, Maharashtra, India 2,3,4,5 Students, Dept. of Mechanical Engineering, Bharati Vidyapeeth College of Engineering, Navi Mumbai, Maharashtra, India ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Cigarette smoking causes serious diseases through frequent and prolonged exposure to toxicants. Technologies are being developed to reduce smokers’ toxicant exposure, including filter adsorbents, tobacco treatments and substitutes. This study examined the effect of modifications to filter ventilation, and active charcoal filter length and loading, as well as use of porous substances and chemical reactions, on the yields of toxicants in cigarette smoke. Earlier, an air-dilution mechanism, called splittipping, was developed in which a band of porous paper in the Centre of the filter tipping f...

Impact of Electronic Alternatives to Tobacco Cigarettes on Indoor Air Particular Matter Levels

International Journal of Environmental Research and Public Health

An aerosol study was carried out in a test room measuring particulate matter (PM) with an aerodynamic diameter smaller than 10, 4, 2.5 and 1 µm (PM10, PM4, PM2.5, PM1) before and during the use of electronic alternatives to tobacco cigarettes (EATC) IQOS®, GLO®, JUUL®, with different kinds of sticks/pods, as well as during the smoking of a conventional tobacco cigarette. The aerosol was mainly in the PM1 size range (>95%). All studied EATCs caused lower indoor PM1 concentrations than conventional tobacco cigarettes. Nevertheless, they determined a worsening of indoor-PM1 concentration that ranged from very mild for JUUL®—depending on the pod used—to considerably severe for IQOS® and GLO®. Median values ranged from 11.00 (Iqos3 and Juul2) to 337.5 µg m−3 (Iqos4). The high variability of particle loadings was attributed both to the type of stick/pod used and to the different way of smoking of volunteers who smoked/vaped during the experiments. Moreover, during vaping IQOS® and GLO®...

Particulate Matter Emissions of Four Different Cigarette Types of One Popular Brand: Influence of Tobacco Strength and Additives

International Journal of Environmental Research and Public Health, 2019

The inhalation of particulate matter (PM) in second-hand smoke (SHS) is hazardous to health of smokers and non-smokers. Tobacco strength (amount of tar, nicotine, and carbon monoxide) and different additives might have an effect on the amount of PM. This study aimed to investigate the influence of tobacco strength or additives on PM. Four cigarette types of the brand Marlboro with different strengths and with or without additives were analyzed in comparison to the 3R4F reference cigarette. SHS was generated by an automatic environmental tobacco smoke emitter (AETSE) in an enclosed space with a volume of 2.88 m³. PM concentrations (PM10, PM2.5, PM1) were measured with a laser aerosol spectrometer followed by statistical analysis. The two strongest Marlboro brands (Red and Red without additives) showed the highest PM concentrations of all tested cigarettes. The measured mean concentrations Cmean of PM10 increased up to 1458 µg/m³ for the Marlboro Red without additives (PM2.5: 1452 µg/...

Passive Exposure to Pollutants from a New Generation of Cigarettes in Real Life Scenarios

International Journal of Environmental Research and Public Health

The use of electronic cigarettes (e-cigarettes) and heat-not-burn tobacco (HNBT), as popular nicotine delivery systems (NDS), has increased among adult demographics. This study aims to assess the effects on indoor air quality of traditional tobacco cigarettes (TCs) and new smoking alternatives, to determine the differences between their potential impacts on human health. Measurements of particulate matter (PM1, PM2.5 and PM10), black carbon, carbon monoxide (CO) and carbon dioxide (CO2) were performed in two real life scenarios, in the home and in the car. The results indicated that the particle emissions from the different NDS devices were significantly different. In the home and car, the use of TCs resulted in higher PM10 and ultrafine particle concentrations than when e-cigarettes were smoked, while the lowest concentrations were associated with HNBT. As black carbon and CO are released by combustion processes, the concentrations of these two pollutants were significantly lower f...

Effect of cigarette filter components on its efficiency and smoking characteristics of cigarettes

2018

The study was aimed to evaluate the cigarette filter characteristics i.e. ventilation, pressure drop and retention of tar and nicotine as affected by components used. The improvement of filter characteristics as well as smoking characteristics of cigarette as affected by improved cigarette filter was also endured. Cellulose acetate at 210 mg, tipping paper rows (1, 2 and 4) and pressure drop were studied compared to the applied parameters. It was found an increase in nicotine and tar retention from 44.61 to 48.46, 59.23 and 62.31%, and! 48.87 to 51.54, 64.31 and 70.14%, respectively. Ventilation was also increased from 11.13 to 18.89, 49.23 and 53.46%. While a decrease in pressure drop of cigarette from 135 to 126, 103 and 83 mmWG. The smoking characteristics of cigarettes were as indicated by sensory evaluation and the modified sample had almost the total acceptable (72) as for the imported foreign samples (72, 72, 74 and 72). But the modified sample by using 200 mg cellulose aceta...
