  • Urban Air Quality Management

    ' Poor air quality due to pollution is a serious environmental problem in most urban areas. The greatest burden of pollution is on human health. Urban air quality management requires an integrated approach that (i) identifies the most serious problems and measures that offer cost-effective and feasible solutions across a range of economic sectors and pollution sources including industries, ...

  • What is sustainable air quality?

    For 40 years or more, air quality policy has been based on the paradigm of the air quality standard as a uniform criterion of acceptable environmental degradation, built on the foundations of the precautionary principle. However, developments in health science have undermined some of the underlying assumptions of this paradigm whilst technological emission controls have been offset by growing ...

  • 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 ...

  • The application of Eulerian models for air quality prediction and the evaluation of emission control strategies in Canada

    The Canadian Hemispheric and Regional Ozone and NOx System (CHRONOS) has been designed for the prediction of atmospheric oxidants on both regional and hemispheric scales. The model simulates dispersion and complex chemistry of nitrogen oxides and volatile organic compounds (VOCs) using inventories of actual anthropogenic emission. The meteorological input for the model is provided by the ...

  • Update and revision of Turkish air quality regulation

    The Air Quality Assurance Regulation (AQAR) was issued on October 1986. This regulation was basically a direct translation of the German TA-Luft of 1984. The main purpose of AQAR was to control the effect of industry, domestic heating and Traffic on ambient air quality which previously had not adequately been represented. Two new regulations, "Industry Related Air Pollution Control Regulation" ...

  • Controlling Air Pollutants case study

    While it's not always easy to determine what's required for compliance, new technologies can help achieve air-pollution control Selecting air-pollution control equipment can be tricky. It's not only difficult to determine which pollutants must be controlled, but also which type of equipment will best control them to required levels for any given process or facility because there is no ...

  • 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 ...

  • Air quality assessment in the EU: room for improvement?

    Different modelling approaches are used to design and assess air quality plans across Europe. This study assessed the strengths and weaknesses of these different approaches. The researchers conclude that a large variety of models is in use, without a preferred or standard model having emerged yet. They identify integrating local-scale and large-scale models and verifying models with measurements ...

  • Confronting allegations of air quality non-compliance

    A facility with an air quality permit must comply with all the conditions of that permit and demonstrate its compliance on an on-going basis. Unfortunately, no matter how diligently the facility and corporate staff strives to assure continuous compliance, unexpected compliance challenges can occur. For example, new equipment fails the emissions guarantees provided by equipment vendors; new staff ...

  • Air quality and ancillary benefits of climate change policies

    Action to combat climate change will deliver considerable ancillary benefits in air pollution abatement by 2030. The ancillary benefits will be: • lower overall costs of controlling air pollutant emissions in the order of EUR 10 billion per year; • reduced air pollutant emissions, leading to a fall in damage to public health (e.g. more than 20 000 fewer premature deaths/year) and ecosystems. ...

  • Double benefit of monitoring Indoor Air Quality (IAQ)

    It is a difficult balance to save money and energy yet maintain a comfortable and healthy indoor air environment. A logical solution to controlling indoor air pollution is good ventilation coupled with IAQ monitoring using gas sensors. This can ensure healthy indoor air as well as a more efficient HVAC system.  Typical IAQ investigation and examination consists of taking single-point ...

  • Idealized Air Quality Regulation: A One-Atmosphere Approach

    After almost 40 years of experience with the U.S. Clean Air Act (CAA), many of the original goals of the regulation have been achieved. The CAA and its subsequent amendments have been driven largely by science and technology, linking the Earth’s atmosphere with public health and welfare and sources of pollution. Knowledge in the 1960s about the atmosphere that ...

  • Controlling Hazardous Air Emissions With A Catalytic Oxidizer

    As the full effect of the Federal Clean Air Act (CAA) Amendments continue to impact today’s industry, many companies will be required to install new or additional air pollution control equipment.
