  • Analysing coloured smoke | Pearl or Quest?

    Coloured smoke consists of an aerosol of tiny particles which is combusted or vaporized. The particular pigment or dye of each colour affects the colour of the smoke. The mixture usually includes a cool-burning formula based on potassium chlorate oxidiser, dextrin or lactose as fuel. Then one or more dyes are introduced to account for around half of the mixture. A small amount of sodium ...

  • Controlling Railroad Smoke: An Historical Perspective on Regulatory, Educational, and Technological Options

    Control of pollutants from mobile sources has been a persistent problem for well over 100 years. While today’s focus is primarily on emissions from the internal combustion engine, before 1960, clean air crusaders considered the coal-burning steam locomotive the mobile source most affecting urban air quality.  The problem of controlling railroad smoke ...

  • Don’t Let Profits Go Up In Smoke

    In today’s competitive economy, few businesses have “money to burn.” For manufacturing companies that installed air pollution control systems more than seven to 10 years ago, though, these older, less efficient systems could literally be “burning money” by operating inefficient electric motors and by allowing large amounts of useable heat energy to bevented directly out the exhaust stacks. ...

  • When the smoke disappears: dealing with extinguishing chemicals in firefighting wastewater

    Water is not enough. Nowadays, numerous chemicals are used for fire extinction. After use, however, these may unintentionally enter sewerage systems. In order to safely treat firefighting wastewater (FFWW), knowledge of the potential effects of these chemicals on biological treatment processes is essential. This study characterized and mimicked the composition of FFWW containing two powders, ...

  • Effect of maternal obesity and passive smoking on neonatal nucleated red blood cells

    Passive cigarette smoking and obesity during pregnancy are risk factors for adverse outcome in infant. Elevated umbilical cord neonatal nucleated red blood cells (NRBCs) have been suggested as a marker of intrauterine foetal hypoxia. Aim to demonstrate whether maternal risk factors during pregnancy are capable of elevating circulating NRBCs measured at birth. We compared the count of NRBCs in the ...

  • Smoking relapse prevention intervention: a study of postpartum women in Lodz, Poland

    Approximately 30?40% of pregnant women, who smoke prior to pregnancy, tend to quit smoking by the first prenatal visit but more than half of them relapse to smoking after delivery. Interventions to maintain quitting smoking after delivery were so far rarely performed and their effectiveness is not well documented. The aim of this study was to evaluate the effectiveness of the smoking relapse ...

  • Don´t Let Your Energy Go Up In Smoke

    Competitive pressures and unpredictable energy costs continuously motivate us to examine our processes for opportunities to increase quality and productivity, and to decrease costs. Energy-intensive processes such as those associated with the manufacture of a wide variety of  products utilizing water or VOC-based solvents offer opportunities to reduce operating costs through heat ...

  • Smoke Factory Chooses Automatic Self Cleaning Filter for Efficient and Effective Chiller Protection

    BACKGROUND Cooling towers dissipate both ambient and process heat in most large manufacturing facilities.  These structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere.  Problems with efficient heat transfer, equipment protection and pathological risks to employees can most often be traced back to an issue with suspended ...

  • Comprehensive analysis of tobacco smoke using TD–GC×GC–TOF MS with Tandem Ionisation

    The hazardous constituents of cigarette smoke have attracted considerable attention lately, especially with increasing regulation around the world limiting or banning smoking in public places – and even in private cars if children are present. From an analytical perspective, however, there is much that remains to be learnt about the composition of cigarette smoke, because of its high degree ...

  • Tobacco smoke-dependent changes in cytochrome P450 1A1, 1A2, and 2E1 protein expressions in fetuses, newborns, pregnant rats, and human placenta

    Tobacco smoke (TS) was described as a mixture of numerous cytochrome P450 (P450) substrates, inducers, and inhibitors. These inducers and inhibitors may modify drug clearance and xenobiotic or endogenous metabolism affecting P450s expression. In the present study, the effect of gestation and TS on: (1) cytochrome P450 CYP1A1, CYP1A2, and CYP2E1 protein expressions, and (2) cytochrome P450-linked ...

  • Intelligent Pollution Control

    The world faces difficult pollution control decisions. For every dollar spent on pollution control, there is an alternative investment in health improvement. For every dollar spent on reducing one pollutant, there is an alternative to reduce another. The most prudent course to make the best investment should include: Intelligent uncertainty Intelligent classification of options ...

  • A new paradigm for tobacco control policy and legislation

    Substantial research on the effects of Environmental Tobacco Smoke (ETS) has been published over the past few decades, which resoundingly warns of the severe health hazards caused by ETS. Tobacco control policy and legislation has also evolved rapidly over the course of the past few decades as a response to a variety of social, economic, political and legal forces. Consequently, the present realm ...
