  • Documentary highlights the dangers of air pollution

    “Under the Dome" showcases huge problem in China The “fog” blanketing China most days used to be thought of as a natural weather phenomenon that couldn’t be helped. But since 2012, the words “smog”, “PM2.5”, “air pollution” and “fine particles” have become analogous to a nation’s struggle against an ...

  • Air pollution by ozone in Europe in summer 2006

    This report provides an evaluation of ground-level ozone pollution in Europe for April-September 2006 based on information submitted to the European Commission under Directive 2002/3/EC on ozone in ambient air. Since the submitted data have not yet received their final validation by Member States, the conclusions drawn in this report should be considered as ...

  • Air pollution by ozone in Europe in summer 2005

    Ground-level ozone is one of the air pollutants of most concern in Europe. Ozone pollution is produced by photochemical processes involving nitrogen oxides and volatile organic compounds in the lower parts of the atmosphere. Ozone levels become particularly high in regions close to high ozone precursor emissions and during summer when stagnant meteorological conditions with high insolation and ...

    Untitled Document In summer 2004, the levels of ground-level ozone were high in ...

  • Air pollution facts, 5 pollution facts you should know!

    Air Pollution Facts Most Don't Know The air we breathe becomes polluted for many reasons. Emissions from cars and trucks, chemicals from industrial production and that list can go on. Many people consider themselves air pollution experts -it is after all a hot topic and common discussion point that many of us want part of and to demonstrate our knowledge. The best way to tackle air ...

  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • Dispersion models and air quality data for population exposure assessment to air pollution

    Evaluating the extent of exposure to chemicals in absence of continuous measurements of their concentration in air and direct measures of personal exposure is crucial for epidemiological studies. Dispersion models can be a useful tool for reproducing spatio-temporal distribution of contaminants emitted by a specific source. However, they cannot easily be applied to short-term epidemiological ...

  • The Benefits of an Integrated Air and Water Pollution Control Partner

    Although there has been substantial progress during the past several decades in reducing pollution, the EPA, other federal agencies and local governments continue to add and revise requirements and standards, making compliance a challenge for the industrial sector. These companies also face increasing public pressure not just to meet but to exceed pollution control standards, as studies continue ...

  • National Air Pollutant Emission Trends, 1900-1998

     Executive Summary What information is presented in this report? This report presents the United States (U.S.) Environmental Protection Agency’s (EPA) latest estimates of national emissions for criteria air pollutants: carbon monoxide (CO), nitrogen oxides (NOX ), volatile organic compounds (VOC), sulfur dioxide (SO2 ), particulate matter (PM) less than 10 ...

  • Company makes ink out of India’s air pollution

    India’s dirty secret has a silver lining: The air pollution that is affecting millions of people in the country’s traffic-jammed cities can be turned into creative human expression with the help of a clever invention. A team of four young scientists have developed a special device that collects carbon soot from engine exhaust. They then turn the collected particulate matter into ...

  • Selections from the history of environmental pollution, with special attention to air pollution. Part 1.

    Several comprehensive publications have been issued recently on the environmental pollution of past times (e.g. Tylecote, 1976; Nriagu, 1983a; Brimblecombe, 1987a; Goldstein, 1988; Healy, 1988; Brimblecombe and Pfister, 1990; Hughes, 1993; Markham, 1994; Brimblecombe, 1995; Karatzas, 2000, 2001; McNeill, 2001; Meszaros, 2001). The aim of this study is to give an overview of information on the ...

  • A project "Transformation of air-pollution, modelling its transport and dispersion"

    Information about a new project is given in this contribution. The project is financed by the Czech Ministry of Environment and deals with the problem of summer photochemical smog formation. Field campaigns and utilisation of existing monitoring network data are supposed for analysing both biogenic emissions and emissions due to human activity. An important part of this project consists in ...

  • Air pollution by ozone across Europe during summer 2010

    Ozone is a 'secondary' pollutant formed in the lower part of the atmosphere (the troposphere) from complex photochemical reactions following emissions of precursor gases such as nitrogen oxide and volatile organic compounds. Ozone is a powerful oxidising agent and one of the air pollutants of most concern in Europe. In Europe, ozone concentrations are also influenced by emissions in other ...

  • Air pollution by ozone across Europe during summer 2012

    Despite efforts to mitigate ozone pollution, the number of exceedances of EU ground-level ozone concentration standards for protecting human health (Directive 2008/50/EC) remained at serious levels during summer 2012 (1). In the summer of 2012, the threshold of 120 micrograms per cubic metre of air (ìg/m3) maximum daily eight-hour mean was exceeded on more than 25 days again across large ...

  • Air pollution forecast in Portugal: a demand from the new air quality framework directive

    This work aims at developing and validating a numerical air quality operational forecasting system that will be applied over Portugal. The CHIMERE model was chosen for the chemistry-transport simulation using the meteorological parameters supplied by the MM5 mesoscale meteorological model, forced by the AVN/NCEP global forecasts. An experiment of 48-hour real-time forecast simulations was ...

  • Revealing the costs of air pollution from industrial facilities in Europe

    This European Environment Agency (EEA) report assesses the damage costs to health and the environment resulting from pollutants emitted from industrial facilities. It is based on the latest information, namely for 2009, publicly available through the European Pollutant Release and Transfer Register (E-PRTR, 2011) in line with the United Nations Economic Commission for Europe (UNECE) Aarhus ...

  • Air pollution by ozone across Europe during summer 2009

    Ozone levels during summer 2009 were as low as during summer 2008 and according to several indicators were among the lowest since reporting of Europe-wide data commenced in 1997 (1). Average temperatures in summer 2009 were generally higher than in 2008 and close to those measured in the extremely hot summer of 2003 when the highest number of exceedances in the last decade occurred. However, ...
