  • Implementing QALYs in the Analysis of Air Pollution Regulations

    In recent years, there has been growing interest in cost-effectiveness analysis for environmental regulations using quality-adjusted life years as the measure of effectiveness. This paper explores the implications of the QALY approach for measuring the impacts of air pollution regulations, with an example using the U.S. Environmental Protection Agency’s Heavy Duty Engine/Diesel Fuel regulations. ...

  • Effects of nanoparticle-blended water?biodiesel emulsion fuel on working characteristics of a diesel engine

    An experimental investigation is carried out to establish the performance, emission and combustion characteristics of a diesel engine using jatropha biodiesel, jatropha biodiesel emulsion fuel (5% of water, 93% of biodiesel, 2% of surfactants) and alumina-nanoparticles-blended jatropha biodiesel emulsion fuels. The nanoparticles are mixed with the biodiesel emulsion fuel in the mass fractions of ...

  • London’s reliance on diesel triggers re-emergence of an old enemy: smog

    It’s Christmastime on Oxford Street. Brilliant displays of white lights rain from above. Decked-out shoppers dash from one gaudy sale to the next. And Johnny Conquest breathes in poison. “The air is horrible. The taxis stop right here, and when they take off, boom, you can taste it,” says the 67-year-old as the heavenly smell of the caramel peanuts he hawks from a humble street ...

  • Traffic emission effects on ambient air pollution by PM2.5–related PAH in Upper Silesia, Poland

    The ambient concentration of particle–bound polycyclic aromatic hydrocarbons (PAHs) was investigated in two industrial towns in Upper Silesia, Poland. The 24 h samples of PM2.5 (particles with aerodynamic diameter ≤ 2.5 µm) were collected simultaneously at busy roads (or crossroads) and at an urban background site. Additionally, the samples were collected during the heaviest traffic density (rush ...

  • Midwest contractor turns pollution into profits - Fred Weber

    Ed Moss knows a good thing when he sees one.  When Moss, maintenance manager for the major construction firm of Fred Weber, Inc., first tried out a fuel-saving device on one of the company’s diesel engines, something clicked right away.  Those first test results, conducted on an engine loading limestone at a mine, showed a fuel savings of 33 per cent, Moss said. What’s more, when his ...

  • Air as Clean as the Driven Snow

    While California is the most populated state in the nation, it is also home to some of America’s most natural and pristine wilderness and recreation areas. One such venue is the Snow Summit Ski Resort in Big Bear Lake.  Situated just over two hours from Los Angeles, Snow Summit is a fullservice winter resort that opened in 1952 and operates an average of 142 days a year. ...

  • A quantitative approach to the traffic air quality problem: the traffic air quality index

    The Traffic Air Quality (TAQ) model is a simple tool to estimate traffic fine particulate emissions on roadways (g/km) and can be used for both real-time analysis and for localized conformity analysis (“hot-spot” analysis for nonattainment areas) as defined by 40 CFR 93.123. This paper is a follow-up to a study published earlier regarding the development of the TAQ model. This paper shows how ...

  • Case study - Engine cell exhaust: Catalytic oxidizer

    Overview Endurance testing of outboard motors for boats has typically been done in lakes and sometimes on barges. This testing was time consuming, presented logistic problems and removed the testing from the R & D department and the factory. When a company in Oklahoma decided to build their own endurance test cell area, the Environmental Protection Agency required them to control the ...

  • How we can vanquish pollution within our lifetimes

    Simply spreading the message could change the world The following is excerpted The Brown Agenda: My Mission To Clean up The World’s Most Life-Threatening Pollution by Richard Fuller, and is published here with permission from the author. Pollution is the leading cause of death in low- and middle-income countries. The top 10 ...

  • Air quality issues drive vehicle alternatives

    Vehicle exhaust systems remain a major source of air pollution in cities, despite the progress being made to reduce emissions from new models. Energy World takes a look at efficiency improvements, and the alternative fuel alternatives to petrol and diesel. In early April, the south of Britain woke to a hazy blanket of smog. A few weeks earlier, Paris had choked and spluttered through its own ...

  • Ambient Air Quality in India - An Alarming Report

    Are we mortgage India against air pollution? The answer may be “Yes”. The reason is India has witnessed a phenomenal increase in the number of industries and vehicles in the last decade, along with the mushrooming of cities. As a consequence, there has been a dramatic deterioration in the quality of urban air in most regions of the country particularly in big cities like Delhi, Mumbai, Kolkatta ...


  • Fast Action to Reduce the Risks of Climate Change: U.S. Options to Limit Short-Lived Climate Pollutants

    Short-lived climate pollutants such as soot, methane and hydroflurorocarbons (HFCs) account for 30 to 40 percent of global warming to date. Targeted efforts to reduce these emissions can slow the pace of global warming and moderate climate impacts already underway, including the melting of sea ice and glaciers. By reducing local air pollution, such measures would also produce substantial public ...

  • AQMesh used to measure local air quality at Surrey school

    Cleves School in Weybridge, Surrey (UK) has used AQMesh to measure pollution at the primary school’s entrance. The project, led by Dr. Edward Salter over the school’s summer term, aimed to understand exposure of the children (aged 7-11) to dangerous pollutant gases, with particular interest in the levels of nitrogen dioxide (NO2) and ozone (O3). Initial findings showed that levels of ...

  • Urban Air Quality Forum to Focus on Environmental Impacts of Fuel Choices in Developing Countries

    When chemist Miriam Lev-On, Ph.D., recently visited Agra, India, she toured the region and viewed the grandeur of the Taj Mahal—the 17th Century mausoleum that is one of the world's most celebrated monuments. But as memorable as the Taj Mahal ...


  • Warehouse Optimization: Balancing Equipment Performance and Worker Safety Through Emissions Measurements and Air Quality Monitoring

    Successful warehouse functionality is dependent on both maximizing equipment performance and providing a safe and healthy environment for workers that encourages productivity. However, these two factors are often at odds with each other as warehouse equipment such as forklifts, burnishers and delivery trucks emit toxic gases that can have the potential to create poor indoor air quality which ...

  • CAS DataLoggers Helps You Get Ready for RICE NESHAP

    Manufacturers across the country are scrambling to prepare for RICE NESHAP, an incoming EPA regulation intended to reduce pollutants from several categories of new, existing and reconstructed stationary engines. The focus is on air toxics, and all applicable diesel and non-diesel engines must be retrofitted with an emission control product to meet the new requirements by 2013. Every diesel ...

  • Assessing the impact of particulate matter sources in the Milan urban area

    The Chemical Mass Balance (CMB) receptor model of the US-EPA was applied to PM10 data obtained during a field study performed in the Milan urban area, including daily average concentrations, element and ion concentrations. Two chemical fingerprints were estimated to characterise total traffic emissions and diesel engine exhaust emissions. Four main source groups were identified: road traffic, ...
