  • Persistent organic pollutants in the Arctic

    Persistent organic pollutants (POP) have been subject to research at NILU for a long time. These substances are toxic and are of anthropogenic origin, they accumulate in the environment, and they move through the environment so that after a discharge their traces including transformation products can be found in far-away places in air, water, soil and biological ...

  • 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. ...

  • 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 ...

  • Air monitoring of persistent organic pollutants in the Great Lakes: IADN vs. AEOLOS

    When designing a monitoring campaign, one has to consider many factors in the decision to perform a long-term synoptic monitoring program or a short-term intensive study. Each has its own advantages and disadvantages. This paper compares and contrasts the information obtained from two studies conducted on the Laurentian Great Lakes. One, the Integrated Atmospheric Deposition Network (IADN), is a ...

  • 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 ...

  • Screening of volatile organic compounds as a source for indoor pollution

    For a considerable period of time the presence of an increasing number of chemicals has been observed in almost all aspects of human life. This process also affects the living and working environment of man. Human development, including physical and mental health and well-being, depends on to a great degree on the surrounding environment. Considering that an average person spends a significant ...

  • Cattle egrets as a biosentinels of persistent organic pollutants exposure

    We investigated selected chlorinated pollutants (β-HCH, γ-HCH, DDDs, DDEs, o,p′-DDT, p,p′-DDT, heptachlor, aldrin, dieldrin, and endrin) in the Lahore and the Sialkot districts of Pakistan, using eggs of cattle egret (Bubulcus ibis) collected during May and June 2007. The pollutant with highest level and frequency was ΣDDT, followed by β-HCH, γ-HCH, ...

  • Metals and organic pollutants in snow surrounding an iron factory

    Abstract To estimate air pollution snow samples were collected in March 2001 at six sites in the vicinity of the Kostomuksha factory in Karelia. Seventy-two chemical elements and more than 200 individual organic compounds were identified by inductively coupled plasma mass spectrometry (ICP-MS) and gas chromatography mass spectrometry (GC-MS). It was found that the levels of Li, B, Al, Fe, Ni, Cu, ...

  • 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 ...

  • Integrated Modeling of Fate and Effects of Persistent Organic Pollutants in Marine Ecosystems

    Contaminants reach surface waters through different pathways, ranging from atmospheric deposition, infiltration in the soil during heavy rainfalls and migration with the groundwater or transport in particulate and dissolved phase in rivers. Domestic and industrial sewage water represents a major global source of pollution for surface water. Furthermore, agricultural activities may be associated ...


  • Persistent Organic Pollutants (POPs) in the European Atmosphere: An Updated Overview

    The industrial revolution and the resultant technological society have led to a continuous production and emission of new toxic substances causing gradual and widely diffuse adverse effects to the entire planet usually known as Global Environmental Changes. Climate change, ozone depletion and global distribution of persistent organic pollutants (POPs) are, among other, important examples of ...


  • US Regulation of Wood-burning and Indoor Air Pollution

    Recently, the US EPA released their final proposal to update the new source performance standards (NSPS) for new woodstoves and heaters, and to add NSPS for the first time for pellet stoves, furnaces, hydronic heaters, and masonry heaters.   The measures, if approved, would take effect in 2015.  The report states, "Emissions from wood stoves occur near ground level in residential ...

  • Maintenance solutions for air pollution control equipment

    Manufacturing facilities are constantly under pressure to meet production forecasts at the lowest possible cost. These two goals; production output and cost control, can be difficult to obtain consistently in any manufacturing operation. Additional frustration to meet these goals can be exaggerated in today’s lean manufacturing climates that have trimmed budgets and reduced workforce. ...

  • P2 for SMEs: How to advance pollution prevention in small and medium-sized organizations

    Businesses in the small- and medium-sized enterprise sector are a vital part of the Canadian economy. So-called 'SME' firms have less than 500 employees and less than $50-million in annual revenues. But SMEs are the fastest growing facet of the Canadian economy, and as such are especially important to the successful adoption of pollution prevention (referred to as 'P2' in government circles). SME ...

  • Time to address the air pollution control residue problem

    The incineration of municipal solid waste is gaining increasing importance in the UK, especially as the burning of waste can be used to generate energy, providing a more sustainable solution to our waste problem by diverting it from landfill sites. An issue with incineration is that some of our waste contains hazardous chemicals such as chlorine and lead which are volatilised during the process. ...

  • Transboundary Pollution

    All pollutants can be transported through the aquatic environment and atmosphere, and many accumulate in downstream water bodies and their biota. The probability that pollution will cause transboundary impacts depends on the location of its source in relation to national boundaries, as well as the time it takes for a given pollutant to degrade. In general, microbial pollution is primarily a local ...
