  • Pollution

    Pollution can take many forms. The air we breathe, the water we drink, the ground where we grow our food, and even the increasing noise we hear every day--all contribute to health problems and a lower quality of life. Find out about the environment ...

  • Ammonium, nitrate, and total nitrogen determination in fly ash

    Fly ash is a by-product of the combustion of pulverized coal and is composed of small particles. The composition of the fly ash may vary considerably, however, all fly ashes contain substantial amounts of silicon dioxide (SiO2), aluminum oxide (Al2O3) and calcium oxide (CaO). Nowadays, air pollution control standards require a separation of flue gas before being released to the atmosphere. Fly ...

  • Optimizing VOC Combustion - Case Study

    Volatile Organic Compounds (VOCs) are pre-cursors to Ozone pollution and subject to EPA regulations. Thermal and catalytic oxidizers are routinely used to destroy VOC emissions from a variety of industrial sources. ...

  • Transboundary air pollution research

    No other research institution in Norway has been paid off so well in EU's fifth framework programme as the Norwegian Institute for Air Research (NILU). 'Norway is of no importance to the Europeans', this is the opinion of Director Øystein Hov. 'It's no use promoting Norwegian special points of view in the ...

  • Air pollution from ships

    Emissions from shipping contribute significantly to the concentrations and fallout of harmful air pollutants in Europe. There are however technical means by which these pollutants could be cut by as much as 80-90 per cent, and very cost-effectively compared with what would have to be done to achieve similar results by taking further measures on land-based sources. Such reductions are needed for ...

  • Fireworks air pollution in Slovenia

    Over the 'Christmas–New Year' period 12/2010–01/2011, PM10 air pollution measurements on most of the automatic measuring stations in Slovenia reached extreme values of up to 300 µg/m³. Analysis shows a very close correlation with the timings of the fireworks displays in the areas. This paper shows the other side of this cultural enjoyment - the effect on PM10 air pollution. As the correlation ...

  • Air Pollution Control Specs

    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.  With more than 25 years of proven success in a variety of industries, catalytic and thermal oxidation has become a popular method for controlling volatile organic compound (VOC) and hazardous air ...

  • Common Indoor Air Pollutants

    Is the indoor air you breathe healthy? According to the World Health Organization, 40% of all buildings pose a serious health hazard due to indoor air pollution. The EPA calls indoor air pollution the #1 pollution problem inAmerica. The following is a list of common indoor air pollutants: Dust, Pollen, and Other Allergens Chemical Fumes and Vapors Mold and Fungus Toxic ...

  • History of Air Pollution in the UK

    Concern about urban air quality is not new. Complaints were recorded in the 13th century when coal was first used in London. Since the middle of the 19th century, the atmosphere of the major British cities was regularly polluted by coal smoke in winter, giving rise to an infamous mixture of fog and smoke known as smog. Today the emphasis has shifted from the pollution problems caused by industry ...

  • Inversions and air pollution in Istanbul

    Owing to the rapidly growing and inefficient usage of fuel, air pollution has increased in Istanbul. The levels are affected by the weak dispersion conditions in the city. The strength of the inversion can be explained by the temperature difference between the top and bottom boundaries and their height. In this study, nighttime surface inversion heights have been found to range between 84 m and ...

  • AirQuis: A basis for air pollution forecasting

    The GIS based air quality planning system, AirQUIS, represent a perfect platform for developing numerical air quality forecasting.  AirQUIS The Air Pollution Surveillance and Information System, AirQUIS, has been developed on a Geographical Information System (GIS) platform. The main objective has been to enable direct data and information transfer and obtain a remote quality control of ...

  • 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 ...

  • Evaluation of air pollution trends in Istanbul

    Previously, SO2 and PM10 (particulate matter less than 10 Bm in size) concentration distributions have been investigated in order to assess air pollution in Istanbul during the winter season (November–March) in which the concentration of these pollutants had reached formidably high levels due to the consumption of low-quality fuels (mainly coal) for residential ...

  • Sino-Norwegian air pollution projects

    A co-operation was established in 1995 to start the development of air quality management systems in China. The areas selected for planning were: Yantai for a monitoring and planning system for air and water quality; and Guangzhou for an air pollution optimal abatement planning tool. The projects were based upon a modern environmental surveillance and information system, developed in ...

  • Air pollution in Europe 1990-2004

    Overall picture This report analyses and presents changes in air pollutant emissions and their possible health or ecosystem impacts in Europe covering the period 1990–2004. Emissions of all air pollutants fell substantially during the period 1990–2004 in the 32 EEA member countries (EEA-32), resulting in improved air quality over the region. However, ambient concentrations of particulate ...

  • Alternative Fuels for Air Pollution Control

    Non-traditional, alternative fuels are all the rage now, especially with government pressure forcing increasing numbers of fossil-fired assets to shut down. While wind and solar have a place in our energy future, neither is reliable or inexpensive enough to be the complete answer.  Industry is looking for new fuels that can replace coal, oil and natural gas. Proposed alternative fuels come ...

  • Air pollution potential in Buenos Aires city, Argentina

    A study of the climatology of ventilation properties of the atmosphere in Buenos Aires city has been carried out. From routinely available observational data, the daytime stability conditions and related ventilation factors and airflow characteristics are obtained and studied. In all cases, the seasonal and annual behaviour is analysed. The frequencies of occurrence of daytime reduced ventilation ...

  • Air pollution and inversion features in Istanbul

    Air pollution in the Istanbul metropolitan area arises from three significant sources: industrial and residential fossil fuels and road traffic. In winter this combination pushes air pollution to levels that are dangerous to humans and to plant life. As far as fossil fuels are concerned, total suspended particulates (TSP) and sulphur dioxide are the chief pollutants. In order to investigate the ...
