  • Analyses of human exposure to urban air quality in a children population

    PM levels of less than 2.5 μm and 10 μm and their effect on children health are studied and it is proposed a ventilation system to avoid outdoor air pollution inlet. Results reveal a positive correlation between indoor and outdoor PM concentrations, the importance of indoor sources and outdoor activity, and building permeability relevance. PM size confirms to be also important in matter of ...

  • Air quality in Europe — 2013 report

    Air quality continues to be a very important issue for public health, the economy and the environment. Europe has significantly cut emissions of several air pollutants in recent decades, greatly reducing emissions and exposure to substances such as sulphur dioxide (SO2), carbon monoxide (CO), benzene (C6H6) and lead (Pb). Despite improvements over several decades, air pollution continues to ...

  • Gas Analyser Unit

    Gas Analysers are used in several industries, chemical industries in particualr use gas analysers to monitor their gas emission levels, air quality samples are compared to high purity reference gases to analyse and measure the emissions.  A common practice is to “calibrate” the sample air against clean, dry pure reference gases such as H2, He, Ar, or N2. The ...

  • Cumulative Air Quality Impact Assessments - A Case Study

    Introduction Deregulation across the country has resulted in the proposal of hundreds of new power plants within the last several years.  Each power plant, individually, is required to demonstrate conformance with state and federal air quality regulations.  However, there is still a great deal of public concern over the combined or cumulative impact that all of these proposed ...

  • Solid waste management in Patna – analyses of ambient air and ground water pollution

    Municipal Solid Waste (MSW) in Patna is disposed of in an unscientific manner without considering environmental impacts. The wastes are dumped in the low-lying areas without compliance of the MSWM Rules, 2000. The dumped wastes are mixed with biomedical wastes making it hazardous. Ambient air quality and ground water were analysed at two dump sites to study the possible impacts of MSW. The ...

  • Air quality and ancillary benefits of climate change policies

    The Thematic Strategy on air pollution aims to improve European air pollution significantly by 2020. This report from the European Environment Agency looks a further ten years into the future, and brings together two major policy challenges — combating climate change and reducing air pollution in an integrated way. Thus, the report analyses projected changes in European air quality up to 2030, ...

  • The impact of an airport on regional air quality at Munich, Germany

    In May 1992, the new airport in Munich, Germany, became fully operational. In 1991, two research programmes within the Bavarian Climate Research Programme (BayFORKLIM) in Germany/Bavaria were established to measure, calculate and model the assumed change of the air quality in the vicinity of the new airport. By analysing the synoptic and local weather situation, measured and modelled air ...

  • Managing air quality during regulatory changes

    This paper discusses the regulatory and technical issues associated with the revisions to the US EPA Guideline on Air Quality Models. The proposed guideline includes the models AERMOD, CALPUFF, and ISC-PRIME, all of which contain significant technical improvements over prior models. Differences in modelling requirements are appearing as regulatory agencies and industries use technically superior ...

  • Understanding the Interactions between Climate Change and Air Quality

    There is increasing evidence and scientific consensus that our world’s climate may be changing due to, among other things, fossil-fuel combustion, biomass burning, and forest and soil destruction. Scientific analyses suggest that, as a result of increasing greenhouse gas emissions, there could be substantial changes in seasonal temperature and precipitation patterns, which, in turn, could ...

  • An integrated strategy for urban Air Quality Management in India

    An integrated strategy for urban Air Quality Management adopts a hierarchical approach – graduating from micro to macro-level management of the problem. The paper provides a conceptual framework, and analyses it in the Indian context through energy-environment modelling and local-level studies. The key insights from the analysis are: technology transfers from developed countries promote ...

  • Understanding ambient air quality instrument operating ranges

    In order to maximize the performance of an air quality monitoring station, careful selection of instrumentations is essential. One of the key issues is to have a good understanding of what pollutants need to be measured and at what concentrations. There are several different types of air quality monitoring, these include: Trace/Background Monitoring This is performed in areas where ...

  • 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 ...

  • An ambient air quality monitoring network for Buenos Aires city

    This paper proposes an objective methodology for designing a multi-pollutant urban air-quality monitoring network to detect concentrations greater than reference concentration levels (CL). The network design includes both air quality simulation and an objective analysis based on monitoring tasks. The proposed methodology is applied to the city of Buenos Aires. Pollutants of concern are nitrogen ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Analysing coloured smoke | Pearl or Quest?

    Coloured smoke consists of an aerosol of tiny particles which is combusted or vaporized. The particular pigment or dye of each colour affects the colour of the smoke. The mixture usually includes a cool-burning formula based on potassium chlorate oxidiser, dextrin or lactose as fuel. Then one or more dyes are introduced to account for around half of the mixture. A small amount of sodium ...
